For the past six or more years the author has been working with eggs
of insects. Recently he has paid special attention to eggs of moths. To
date the eggs from more than 150 species representing some 35 or more
families of moths have been collected, photographed, preserved and de-
scribed; also a rough sketch of each species has been made. The investi-
gation thus far shows that distinctive types exist, also characteristics com-
mon to many species are present.
In this article some of the types and common characteristics are shown.
In later publications the author hopes to present more detailed information
on species of given genera and families.2

Most moths deposit their eggs on a host plant or in the vicinity of food
which the larvae will consume upon hatching. Many species deposit single
isolated eggs but the majority deposit their eggs in groups. The most sim-
ple mass occurs where a female deposits 10 to 100 or more eggs in a con-
tinuous flat group (9)3 in such a manner that each egg is separated from
others usually by a distance that does not exceed the greatest diameter of
a single egg. Other species deposit continuous flat masses of firmly con-
structed eggs where every egg is in contact with one to five eggs (10) and
all are sealed together by a strong adhesive. When pliable eggs are de-
posited in a continuous flat mass the eggs within the mass and away from
the border may assume irregular shapes (11), most frequently hexagonal.
When species, possessing scale-like eggs, deposit them in a mass (12)
the eggs often overlap considerably yet none in the mass is completely
covered by other eggs. Among a few species the females deposit a compact
mass of eggs consisting of several layers or eggs are scattered in an ir-
regular manner. Usually these are mixed with bits of wax or froth-like
secretions produced by the female as she oviposits (17).

Eggs of moths vary in size, the smallest being approximate 0.3 mm.
in diameter and the largest seen to date 2.8 mm. in length. The size of an
egg mass may be 3 mm. to 40 mm. or more in length.
The over all shape of a single moth egg is frequently spherical (1) or
oval (7). Others are rod-shaped (4), barrel or cone-like (6), spindle-shaped
(3) or scale-like (2). Oval eggs from a top view may be ovid while others
resemble thick oval wafers (5) with flattened upper and lower surfaces.

1 This investigation was supported by a research grant from the Na-
tional Science Foundation assigned to the Ohio Historical Society State
Museum, Columbus, Ohio. Many of the eggs used in this study were col-
lected in Florida when the author was associated with the State Plant
Board, Gainesville, Florida, 1959-1960. The author is indebted to C. P.
Kimball for the determination of the species of moths from which eggs were

Most eggs of all shapes possess a narrow to broad, flattened base or
lower surface which is adjacent to the substrate on which they rest. Single
isolated eggs (4) or those which are firmly constructed in a mass (10)
usually are fairly constant in size and shape for a given species. When
eggs in a mass are pliable (11) their shapes may vary somewhat.

The color of some moth eggs may be due to pigment located in the
chorion. This is true of thick-shelled eggs among Citheroniidae and Sat-
urniidae (8), which undergo little or no color change during their incuba-
tion period.
Eggs of many species in numerous families possess a chorion that is
translucent, in some cases almost transparent. This is especially notice-
able when the eggs are deposited on clear glass or polyethylene. If highly
translucent eggs are deposited on green foliage the color of the leaf or sub-
strate can be seen through the eggs. Among many species the color of the
embryonic tissue within is visible (24). This is particularly obvious when
portions of the cytoplasm and embryo change in color as the larva develops.
For example among many Phalaenidae red to brown pigment areas appear
as irregular blotches or rings around the margin (26) a few days previous
to hatching. Among other families, especially the Tortricidae, Olethreuti-
dae, Pyralidae, Arctiidae, Notodontidae and others, some species possess
first instar larvae with dark-colored heads and, in some cases, black setae
(14) which, prior to hatching, can be seen through the chorion. When
eggs are in this state of development they are often referred to as the
"black spot stage". In general most eggs of moths that possess a thin
semi-transparent chorion change color a short time previous to hatching.

The overall color of newly deposited eggs for a given species is fairly
constant. It may be some shade of white, yellow, orange, green, blue, red,
brown to near black. Near white and shades of yellow and green are the
most common colors.
The color of the entire egg among some species may undergo a change
6 to 48 hours after deposition. For example among species of Acrolophus
(13) a newly deposited egg is near white. Six to 12 hours after deposition
the entire egg changes to a dark brown or black. Among species of Cram-
bus (23) the color changes from a cream white to orange, pink or red usually
within 48 hours after being laid.

Most eggs of moths when deposited are covered with a thin, clear, ad-
hesive coating which soon hardens. This adhesive coating sticks the eggs
to the substrate on which they rest and also holds them together (10) if
they are adjacent to each other in a mass. The adhesive quality of the
coating varies considerably. Some eggs are deposited without an adhesive
coating or the coating, if present, is ineffective as an adhesive. These eggs
are completely free and roll about if they are deposited in a small glass
container. Typically the eggs of several species of Acrolophus (13) and
Crambus (23) are like this.

Many eggs, possessing an adhesive coating, adhere tightly to plant tis-
sues yet the same eggs if deposited on plastic or polyethylene are not firmly
attached and usually fall off the substrate after they are placed in a pre-
servative. Among some species of Olene the clear adhesive coating is plenti-
ful and appears as small transparent permanent bubbles (15) between and
around the sides of the eggs. In other cases the adhesive coating resembles
a whitewash paste (20) which holds the eggs to the substrate and together
when in a mass.
Among species of Malacosoma a brown, froth-like, adhesive coating (16)
is deposited among and over the tops of perpendicular eggs that have been
placed in a mass partially or completely around a small twig. Some species
of Liparidae (17) and Megalopygidae (19) secrete a loose to thick coating
of wax-like froth, small thread-like strands or waxy material over and among
eggs in a mass. A similar situation exists among species of Schoenobius
in that the female deposits a compact, flat layer of eggs (18) and then
places over the egg mass long, thin, brown or yellowish, hair-like structures
in an irregular or parallel position. These secretions may also be mixed
with thin scales apparently sloughed off from the caudal end of the abdomen
of the female during deposition.

The outer surface of the chorion on a moth egg may be smooth (1) to
rough (22) and brilliant (13) to chalk-like (15). Eggs of some species,
that appear to be smooth to the naked eye, may possess microscopic struc-
tures only visable when magnified 10 to 25 times. These details vary
considerably. Among some species tiny, rounded pimples or dimples are
present on most of the exposed surface while among others inconspicuous,
irregular, hexagonal depressions occur in rows (21) or scattered (5) over
the surface. Eggs of Prionoxystus possess conspicuous depressions (22)
that may be lopsided squares to hexagons. Each darkened depression is
surrounded by a distinct ridge which is frequently lighter in color than
the depression.
Many eggs of moths possess parallel ridges on their exterior. These
may be vertical or horizontal depending upon the position of the eggs on
their substrate. So far as known distinct parallel ridges on moth eggs
are always more or less parallel with a line that is perpendicular to the
micropylar area of the egg. When the micropylar area is at the top of an
egg fixed to a leaf or substrate, the ridges are vertical (28). If the micro-
pylar area is at one end of a free egg resting on its side the ridges are
horizontal. Comparatively few eggs are free (unattached). Eggs of Cram-
bus (23) and Acrolophus (13) are good examples of free eggs that show
ridges in a horizontal position.
Most species of Phalaenidae possess eggs firmly attached to a substrate.
Their faint to conspicuous parallel ridges are vertical (25-28). Each ridge
extends from the top-center or micropylar area to the base or point of at-
tachment of the egg to its substrate. They vary in length and the longest
terminate near the micropylar area. The shorter ridges end at lower points
or they may join with adjacent ridges. The number of ridges present on
the eggs of a given species is more or less constant. Among species seen
to date 10 to 56 may be present. Figures (25) and (28) illustrate two spe-
cies that are different. If the ridges and adjacent grooves are conspicuous,
the number per egg is apt to be small (25).
The upper terminals of vertical ridges near the micropylar area are
usually inconspicuous. Among species of Helicontia the terminals of the
longest vertical ridges are prominent (6), often in the form of thin trans-
lucent flanges or fringes that protrude some distance above the top surface
of the egg. Species possessing ridges often exhibit numerous tiny trans-
verse striae (25) in the grooves between the ridges. These are more or
less constant in number for a given species. If nodules or bead-like spots
occur along the tops of the ridges the striae usually coincide with these
structures. All of the above structures are seen best in living eggs under
high magnification or in enlarged micro-photographs or transparencies.
An interesting variation of ridges exists among species of Celana (29).
These somewhat flattened eggs possess a narrow band of short parallel
ridges adjacent and perpendicular to the outer border of the egg. The
central micropylar area is large and covered with minute depressed hex-
agonal areas.
Another unusual feature associated with moth eggs is found on those
of some species of Noropsis (30). The entire surface of the egg above the
base is covered with small triangular areas and each triangle bears hooked
spines at its three corners.

We recently reported on the successful establishment of the Hawaiian
parasite, Anagyrus antoninae Timberlake3, for control of the Rhodesgrass
scale (Antonina graminis (Mask.)) in south Florida (Questel and Genung,
(1957)'. Because the parasite is tropical and the exceptionally severe win-
ter of 1957-58 resulted in an almost unprecedented series of freezes from
late December through February that were extremely injurious to host
grasses of the scale, we were concerned as to whether the parasites would
survive. The direct effects of the cold on the parasites and the indirect
effects of reduced numbers of the host insect and its host grasses were both
considered to be important in the parasite's survival.
Host material was collected from areas where introduction had been
made earlier. Collections were made after danger from frost had passed
to determine whether parasites could be reared from the sample material
and whether they had survived the winter. Collection and rearing methods
employed have been described previously.4
On March 4, 1958, collections of scale-infested Para grass were made
near Clewiston, Florida, where temperatures had gone as low as 21F.
After the grass was held for 10 days, more than 50 parasites emerged,
showing that survival was high despite the cold. On March 21, 1958, sam-
ple material was collected near the release point in the vicinity of Lake
Worth, Florida. Within five days A. antoninae adults were emerging, an
indication that survival was good in the Lake Worth area where tempera-
tures had dropped to 260-28F. In both areas scale-infested grass was
Since host grasses of the Rhodesgrass scale were so severely injured
and the scales were so scarce, the logical conclusion was that the parasites
must have been reduced in number. However, where living scale-infested
grass stems could be found, survival of the parasites was good. Scale
scarcity at centers of introduction could also be attributed to the parasite's
effectiveness since observations prior to the freezes had shown that scale
populations had been reduced. If these parasites are capable of surviving
a winter as severe as the one described, we may reasonably assume that low
temperatures will not be too serious an obstacle to permanent establish-
ment of the parasite in the southern third of Florida.

The Mite* is no longer mighty

The ability of KELTHANE to
kill on initial contact the impor-
tant mites that endanger your
crops, plus its long residual
action, add up to both effective
and low cost mite control.
KELTHANE cleans up mites fast,
including species that have
developed resistance to phos-
phates. Its long and strong
residual action also means effec-
tive control of migrant mites
and late-hatching colonies.
When used as recommended it
is completely safe for new foliage
and fruit finish. KELTHANE can

be used up to seven days before
harvest. Compatible with most
pesticides, it kills mites, but
will not harm beneficial insects.
To insure thorough coverage
on hard-to-wet foliage, add
TRITON B-1956, the non-oil
spreader sticker. Ask your
dealer for both.

DIAGNOSIS. In general appearance and size this species resembles A.
lagopi (Grube, 1851), A. megalosoma (Overgaard, 1943) and A. perdicis
(Denny, 1942). In each of the above named species, the parameres and
endomeres of the male genitalia are long, slender, and straight; while in
A. minute these structures are short, and the parameres are curved out-
ward at the distal tips. The male genitalia of A. phaeostoma (Nitzsch,
1866) are of a different type (Emerson and Elbel, 1957)'. In addition,
A. phaeostoma is almost twice as large as A. minute.
TYPE MATERIAL: Holotype male allotype female, and paratypes col-
lected by Dr. G. J. Spencer on 15 October, 1949, at Vancouver, British Co-
lumbia, Canada. Additional paratypes from the following locations: Zo-
ological Gardens, London, England, October, 1952; Bridgnorth, Shropshire,
England, 19 September, 1934; New Orleans, Louisiana, 6 December, 1918;
Portland, Oregon, 17 March, 1933; and McAllen, Texas, March, 1937. The
holotype and allotype are in the collection of Dr. G. J. Spencer at the Uni-
versity of British Columbia. Paratypes are in the British Museum (Natural
History), the U. S. National Museum and the collection of the author.


The annual meeting of the Society will be held jointly with those of the
Entomological Society of America and the Southeastern Branch of the
E.S.A. at Miami from November 27-30. Headquarters of the Florida En-
tomological Society and the Southeastern Branch will be at the Columbus
Hotel and those of the National Society at the adjacent McAllister. Ar-
rangements have been made to house the members of the Florida Society at
the Columbus. Members registering at the Hotel should be sure to indicate
their society affiliation.
The meetings of the National Society are expected to be unusually well
attended. It is also hoped that the Florida organization will have the largest
contingent ever to attend its annual meeting. The program should be ex-
ceptionally good and many special events have been planned by the local

lecting trip in St. Lucia. In selecting this name I am also perpetuating an
old and honored tradition among Odonatists by giving a woman's name to
an incredibly lovely damselfly.

green rather than copper or magenta. Pale color of frons extending pos-
teriorly to the rear of the antennae.
Prothorax with front and hind lobes pale, the latter narrower and more
erect than in male. Median lobe dusky dorsally, as in male.
Pterothorax with mesepisternum iridescent greenish, upper half of
mesinfrapisternum dusky. Pale color grayish-yellow, rather than brown-
ish-yellow as in the male. Mesostigmal laminae dark, pale laterally and
posteriorly, with a prominent bifid rounded mesal process flanked by two
lateral processes pointing in a mesal-anterior direction.
Legs as in male.
Wings as in male. One front wing has M, arising between the fifth
and sixth postnodal cross veins and the other at the fifth cross vein.
Abdomen dark dorsally with obscure pale anterior bands on segments
three (narrow) to six, a very obscure pale anterior band on seven, and pale
lateral spots on eight and nine. Sterna of six and seven distended ven-
trally. Ventral margin of valves of ovipositor finely serrated apically.
Dimensions: Total length: male 38 mm.; female 34 mm. Abdomen:
male 33 mm.; female 29 mm. Hind wing: male 17 mm.; female 19 mm.
Type locality: Cul de Sac River, near Bexon, Castries Quarter, St.
Lucia, British West Indies. Specimens collected on 7 September, 1957.

The general appearance and wing venation of this species are typical
for Protoneura s. str. as defined by Williamson (1915, pp. 616-625)2 How-
ever, this species is immediately set apart from all others in the genus by
the most peculiar labyrinthine superior appendage of the male. The female
resembles that of P. capillaris (Rambur) but has mesostigmal laminae
of a different shape. The other West Indian Protoneura is capillaris, which
is abundantly distinct from ailsa. There is a good possibility that the so-
called capillaris from Puerto Rico and the Virgin Islands may have to be
referred to another species (Westfall, personal communication), but this
problem is in no way related to that of the relationship between ailsa and
capillaris s. lat. The new species ailsa is dominantly red in the male,
whereas capillaris is dominantly blackish and violet (Cuba) or iridescent
blue-green (Virgin Islands). The superior appendage of ailsa is short,
equant, and labyrinthine, whereas that of capillaris s. lat. is as long as the
inferior, subcylindrical, with a ventral apical tooth.
I would like to acknowledge discussions of the Protoneura capillaris
problem with Minter Westfall, who also criticized this manuscript. Harold
Grant, D. E. Kimmins, and Ashley Gurney kindly made available the col-
lections of the Academy of Natural Sciences, Philadelphia, the British
Museum, and the United States National Museum, respectively.

The rapid development of resistance to insecticides in house flies (Musca
domestic L.) indicates an urgent need for other approaches or alternate
means for their control. The use of repellents appears to be practicable
in restricted areas and under favorable conditions to relieve the annoyance
caused by these insects and to reduce the contamination which is associated
with their presence. LaBrecque and Wilson (1959)' reported the results
of laboratory tests with 65 compounds as vapor or contact repellents to
house flies. This paper presents the results with 26 additional chemicals
tested by the same methods. Some of the compounds were received from
commercial laboratories where they had been developed as fly repellents
and others were selected because they showed repellency in other types of
tests conducted at our laboratory.
Briefly, the test method was based on the numbers of female flies caught
in 30 minutes in traps made of drinking glasses baited with Edamin (a
casein hydrolysate) and capped with white cardboard funnels. The number
caught in a trap with an untreated funnel divided by the number in a trap
with a treated funnel gave the repellency ratio. The repellents were ap-
plied at 200 milligrams per square foot, and treated funnels were tested
after various periods of aging up to 12 weeks, or until the repellency ratio
fell below two.
The results with 12 compounds that gave ratios above two after aging
for two days or longer are given in table 1. Four compounds were effective
throughout the entire 12-week testing period, namely n-octylsulfinylbu-
tyronitrile, decyl lactate acetate, n-octylmercaptobutyronitrile, and diiso-
hexylamine. Deet, which has been outstanding as a repellent for personal
protection against mosquitoes and biting flies, was effective for two weeks.
The following compounds gave ratios of less than two during the first
two days of aging:

The abdomen varied in color from olive green to dark brown. Wing
length, range 1.4-1.6; mean 1.49 mm (5); leg ratio, range 1.5-1.7; mean 1.6
(3); Antennal ratio, range .83-1.1; mean .98 (3). The species apparently
occurs throughout the year.
DIAGNOSIS: This find represents the first record of the subgenus from
the Nearctic region. The species differs from those described by Freeman
(1957) in several genitalic features. However, the structure of the prono-
tum, the absence of frontal tubercles, and the reduced mouthparts would
indicate inclusion in Nilodorum. The reduced mouthparts together with the
distinctive genitalia serve to separate this species from all other nearctic

MALE HOLOTYPE: Everglades City, Florida, 1 Nov., 1960 (USNM).
Wing 1.4 mm long; L. R. 1.4; A. R. 1.7. Frontal tubercles very small,
only about as long as their diameter. Palpal segments in ratio of 15:33:
48:76. (paratype).

2It is with pleasure that I name this species in honor of Dr. James E.


The Florida Entomologist

Thorax pale tan; P. A. bristles 3-4; D. L. in single row; D. M. in double
row; scutellum with two large apical bristles and about 6-8 finer bristles
in a transverse row; head, antennal flagellum, mesonotal vittae, and fore-
legs light brown, mid and hind legs stramineous with distal tarsal segments
Abdomen pale green, becoming brown toward apex. Wing pale, anterior
veins slightly darkened; squama with only 1 hair.
GENITALIA: (Fig. 2) Style stout with lobe-like swelling on inner mar-
gin, sometimes rather acute; superior appendage rod-shaped with irregular
pointed apex bearing two setae.
FEMALE: unknown.
PARATYPES: 2 males, Everglades City, Fla., 1 Nov., 1960 (JES, one;
UF, one). 1 male, Floral City, Fla., 2 July, 1957. 2 males, Sanibel, Fla.,
5 Nov., 1957; 1 male, 9 Aug., 1957. 1 male, Ft. Myers, Fla., 25 Oct., 1957.
Wing length, range 1.4-1.7; mean 1.45 mm. (5); leg ratio, range 1.36-1.4;
mean 1.38 (3); antennal ratio, range 1.3-1.7; mean 1.45 (4). The abdomen
in this species is often pale tan, rather than green, with the base of each
abdominal segment slightly darkened. All specimens are from light traps.
The species was taken throughout the year.
DIAGNOSIS: This species superficially resembles abortivus Malloch in
the shape of the superior appendage of the male genitalia. However, the
well-developed inferior appendage, beset with conspicuous microtrichia,
and the unusually heavy style serve to distinguish this species from aborti-
vus as well as all other nearctic forms.
I wish to express my appreciation to Dr. J. E. Sublette and to W. M.
Beck, Jr., for help with this manuscript.

Records are given for 21 species of Chironomidae not previously recorded
from Florida. New species Chironomus (Cryptochironomus) sublettei and
Chironomus (Nilodorum) devineyae are described. The latter represents
the first Nearctic record for the subgenus Nilodorum. These 23 species
bring the total known Chironomid fauna of Florida to 133.

The Flint-Chattahoochee-Apalachicola Region of Georgia, Florida, and
Alabama has been of interest to students of natural history in the South-
eastern States for many years. A survey of the biota of this region was
undertaken by the Florida State Museum when part of the area became
threatened with inundation (Hubbell et al., 1956). In order to collect psocids
for the survey, I visited this region with other biologists from the Uni-
versity of Florida in June, 1953, and again in March, 1954. Prior to the
initiation of the survey, I had made two collecting trips to Torreya State
Park, Florida. This paper is based primarily on the specimens taken on
these four trips. In addition, some specimens are treated which were col-
lected by P. B. Kannowski and T. J. Cohn on a trip to this region in June,
1956. I also include the very few literature records of psocids from the
area (distribution records of Chapman, 1930).
To date only 38 species of psocids have been found in the region under
consideration. I believe that this represents less than half of the number
of species which actually occur there, for the Florida psocid fauna far
exceeds 100 species, and the great variety of habitats in the Flint-Chatta-
hoochee-Apalachicola region probably harbor many species. Also, the fact
that two undescribed species known only from this region are represented
by a single specimen each, indicates that much more collecting is needed
before the fauna becomes well known.
Until 1952, the states of Georgia, Florida, and Alabama comprised
almost virgin territory for psocid collecting. This is still true of Georgia
and Alabama, but Florida is now somewhat better known. Nevertheless,
very little conclusive evidence can be presented about the ranges of the
species treated in this paper.
HABITATS: After much collecting over a wide area, one becomes aware
that certain situations merit close attention for psocid habitation in con-
trast to a set of situations in which psocids cannot live. Generally, any
terrestrial community is liable to have at least a few psocids. Hence, psocids
are to be found in all of the terrestrial communities discussed by Hubbell
et al. (1956: 29-38), with the possible exception of "lawns and grazed
meadows", and "bulldozed floodplain areas". Generally, psocids are more
abundant and varied in forest communities than in those of shrub and
grassland. The small size and poor mobility of a psocid restrict its ability
to utilize the "whole environment" offered by a major plant community.
Therefore, such a community offers a whole host of habitats, each with its
assemblage of psocids, consisting frequently of a few obligate species and
many facultative species. The major plant community determines the dis-
tribution of these assemblages only insofar as it determines the distribu-
tion of their habitats. Thus an accumulation of leaf litter from broad-
leaved trees may carry the same obligate species of psocids in a dry oak-

land that it does in a ravine forest. Likewise, a clump of the epiphyte
Spanish moss on a cypress branch in a cypress pond is liable to contain the
same assemblage of psocids that occurs in Spanish moss on a magnolia
branch in a sandy hammock. In the two examples cited, the psocid habitat
offers considerably more stable moisture, temperature, and food supply than
the surrounding environment, and this is probably an important clue to the
distribution of all small, rather immobile organisms.
The psocid habitats investigated in the study area and their obligate
species are presented in table I. The obligate species of this table are
either known to be obligate throughout their range or are considered obli-
gate on the basis of certain morphological characters which are probably
adaptive for the habitat. The fact that several habitats have no obligate
species is easy to understand in some cases. Fence posts are virtually the
same habitat as tree trunks. Most of the foliage of the broad-leaved,
dicotyledonous trees and shrubs falls to the ground in this region in the
winter, and psocids of this habitat occur in the ground litter in early
spring. Most psocids apparently do not distinguish between Spanish moss
and dry leaves on a branch. The virtual absence of psocids from cane
(Arundinaria tecta) is not so readily explicable. It probably indicates
that cane bears a very scanty epiphytic microflora.

4. Belaphotroctes sp.
The genus Belaphotroctes has not previously been recorded from the
Western Hemisphere. Three species have been described, one from the
Congo (Badonnel, 1949) one from Angola (Badonnel, 1955) and another
from Natal (Ribaga, 1911). The species listed here is probably new and
has been taken at several Florida localities.

ous 9, 5 nymphs.

5. Embidopsocus sp. a
Like most other members of its genus, this undescribed species inhabits
the space between loose bark and wood of trees, usually dead ones. It has

6. Liposcelis bostrychophilus Badonnel
Liposcelis bostrychophilus Badonnel, 1931, p. 250.
Since my specimens show many characters in common with this Afro-Eu-
ropean species, I believe that they are identical with it. The species has a
wide range in eastern United States, where it is often subcorticolous. In
Europe and Africa it has been found only in domestic situations and on
cultivated plants.

Records are given for 38 species of Psocoptera found in the region of
confluence of the Flint and Chattahoochee Rivers. The unique natural
features of the region, including the endemic conifers Tumion taxifolium
and Taxus floridana apparently harbor no endemic psocid species. An
undescribed species of Lachesilla, here designated Lachesilla sp. a, found
on needle palm, has not been collected outside of this region and may prove
to be endemic. Additional collecting in this region will probably add many
species of psocids to the list.
