IV. Duration of Fertility After Copulation1
The successful development of artificial hibernation quarters
which enabled the cotton boll weevil (Anthonomus grandis
Boh.) to live through the winter while being closely observed,
led to definite. information concerning the longevity of active
spermatozoa in the spermatheca. A low temperature incubator,
brine cooled to hold an average temperature of 550 Fahrenheit,
provided artificial hibernation quarters. Individual weevils
placed in small wire cages filled with Spanish moss provided
that isolation of females which is necessary in order to deter-
mine the length of time spermatozoa can survive in the sperma-
A total of about seven hundred pairs of boll weevils were
observed to copulate; thereupon the females were isolated and
placed in the described hibernation quarters. A temperature of
600 Fahrenheit was maintained for two days after which it was
lowered to and held at 550 Fahrenheit.
Beginning with a seven day period of isolation, several of
the females were removed from hibernation, placed in a con-
stant temperature incubator registering 800 F., and fed fresh
cotton squares. After several days of feeding the weevils began
to lay eggs. By examining the squares daily, egg punctures were
recognized and each square in which the weevil had oviposited
was isolated until the egg hatched. Though the majority of
weevils were allowed to lay but few eggs, due to the scarcity of
cotton squares, several weevils in each group were provided
with squares for continued oviposition. In all cases the eggs
laid were fertile. Following the seven day period, other weevils
were tested after increasing lengths of time, until finally, suc-

cessful oviposition of fertile eggs occurred after one hundred
and seventy-nine days of isolation. This individual continued to
lay eggs until a total of two hundred and one days had elapsed
between the time of copulation and laying of fertile eggs.

The following information is presented in the accompanying
The number of isolated weevils placed in hibernation. Though
large numbers of weevils were isolated, but comparatively few
weevils lived for any considerable length of time. For example,
one hundred and eighty two weevils were isolated and placed in
hibernation quarters November 4th. By April 3rd, all were
dead, none having been used for oviposition tests. Such groups
of weevils are not recorded.
The duration of the period spent in hibernation: A record of
the dates on which the weevils were placed in and subsequently
removed from hibernation quarters. The weevils become par-


tially inactive when placed in an incubator averaging a tempera-
ture of 680 F. They became completely inactive when the tem-
perature was reduced to 550 F. From time to time the isolated
weevils were examined, those which had died were removed.
The number of days without food. This column represents
the number of days each weevil which was used for the oviposi-
tion tests spent in hibernation; a repetition of the "Duration of
hibernation" column, with numerical values substituted for the
recorded dates.
The number of days after copulation during which fertile eggs
were laid. The information presented in this column shows in-
creasing periods of time during which active spermatozoa sur-
vived in the spermatheca.
Number of weevils removed from hibernation and observed to
oviposit. But few weevils were removed at a time from each
group of individuals placed in hibernation. Both the scarcity
of cotton squares, obtainable during the winter months only
from plants grown in the greenhouse, and the difficulty of hand-
ling large numbers of isolated weevils, necessitated experimen-
tation with small numbers of weevils.
It is significant that fertile eggs were laid after a period of
almost seven months after copulation. Oviposition after the
weevil emerges from hibernation is, therefore, not delayed until
chance copulation insures fertilization of the eggs. Consequent-
ly, the ability of boll weevils to lay fertile eggs seven months
after copulation insures early infestation of the cotton fields
in the spring.
The author has not observed parthenogenesis in the boll wee-
vil to occur.

The progress made towards the eradication of the fruit fly
since our last issue has been very gratifying indeed. As a re-
sult of the thorough cleanup of all known and suspected hosts
in and about the infested areas and the systematic spraying with
the poisoned bait, the fly is now very scarce. At the time of go-
ing to press it has been several weeks since a fly has been caught.
Although cage experiments are frequently adding wild fruits
to the known list of hosts, no infestations are being found in
wild hosts in uncultivated areas.

Lymire edwardsi was assigned by Grote to the genus Scepsis
when he described it. Under this old generic name on page 361
of volume II of "Insect Life", Dr. H. G. Dyar described the lar-
val stages in detail.
Distribution: Dr. Dyar obtained his larvae from Dade Coun-
ty, Florida. Since this work was done, Dade County has been
split up to form a part of Palm Beach and Broward counties.
The specimen or specimens which were described by Grote were
taken in Florida but there is no way of placing the definite lo-
cation in the state. During the fall of 1928, specimens were
sent in from Vero Beach, in Indian River County, which is be-
tween one-third and one-half the distance up the coast from the
southern tip of Florida. Specimens were also collected at St.
Petersburg in Pinellas County. These latter had nearly defoli-
ated a fourteen foot rubber (Ficus sp.) tree. From these locali-
ties one would draw the conclusion that Lymire edwardsi is of
general distribution where its host may grow which is the more
semitropical area of Florida.
Parasites: There are two important parasites of Lymire ed-
wardsi, one a hymenopterous, Brachymeria robusta (Crest).
and the other a dipterous, Phorocera claripennis Macq. From
the sixty pupae and larvae coming to us only two moths emerged.
This indicates over a ninety-six percent parasitization. The
Tachina flies were more numerous from the material from Vero
Beach, but there were a few of the Brachymeria also. The ma-
terial from St. Petersburg produced about equal numbers of
these parasites.
The writer wishes to thank Dr. O. A. Johannsen for identifi-
cation of the Diptera and Prof. Harold Morrison for that of the
Hymenoptera. H. E. BRATLEY.


The writer is indebted to Professor Herbert Osborn and Mr.
W. L. McAtee for the determination of most of the material
listed below. The collections were largely made in connection
with a study of the distribution and breeding grounds of the
beet leafhopper, Eutettix tenellus (Baker). A number of the
species have not been previously recorded from Utah, while
new localities are given for many of the forms known to occur
here. Unless otherwise designated, collections were made by

Dunedin, Florida
(Continued from page 37)
Large or medium sized leaf eating Scarabaeidae, varying in
color from pale brownish-yellow to piceous and having the body
loosely built; antennae 9- or 10-jointed, club 3-jointed; front
coxae transverse, not prominent, contained wholly within the
coxal cavities; ventral segment six, connate, but with sutures
distinct; tarsal claws never serrate, but with a single tooth be-
neath. They are commonly known as May-beetles or June-bugs
and their larvae are the well known thick bodied "white grubs"
which do much damage to the roots of corn, grass and other
plants. The beetles vary little except in size and sculpture, and
the principal characters separating them pertain to the male
sex. They were formerly listed under the generic name Lachno-
sterna Hope, but that of Harris has priority by 11 years. About
100 species are known from this country, 29 from Florida. As
I have not been in the State later than May 1, the genus is poor-
ly represented in my collection. In the brief diagnosis of each
species no mention is made of the genital organs of the male.
Persons desiring to use them in their determinations are re-
ferred to the papers of Smith and J. J. Davis and to plates I-V
of the "Coleoptera of Indiana."
*103. (13479). P. latifrons (Lec.)
Length 15-18 mm. Oblong, subcylindrical; purplish-brown to brown-
ish-yellow, usually strongly pruinose, abdomen pale; clypeus entire; an-
tennae 10-jointed in this and the next five species; hind tibiae of male in
this and the following species to No. 125 with the inner spur fixed and
often short or wanting. Male with abdomen deeply impressed, the last
ventral nearly vertical, deeply concave, its apex ending in two small den-
ticles; fixed spur of hind tibiae moderately long.
