TWO NEW THYSANOPTERA FROM FLORIDA1
By J. R. WATSON AND J. R. PREER

Sophiothrips bicolor n. sp.
MACROPTEROUS FEMALE:-Length about .9 mm. Color of head and
thorax brown (raw umber) (Ridgeway's color Standards), basal half of
femora and antennal segment III shaded with the same color; abdomen,
tibiae, tarsi, and apical portions of femora primrose yellow (Ridgeway).
tube somewhat deeper yellow, antennal segments I-VII considerably lighter
(Marguerite yellow-Ridegway). Forewings grayish brown in apical half,
basal fourth darker especially at base, gradually changing to an almost
colorless band just below the middle. Hind wings with a conspicuous
median colorless streak bordered on each side by a dark line which is
much darker on posterior side. A narrow band along each border almost
colorless.
Head but little wider than long, retracted far into prothorax, only
a little wider in the single paratype, cheeks nearly straight and parallel
except for a shallow notch immediately behind the eyes and a slight
rounded protuberance immediately posterior. Dorsal surface very faintly
reticulated, somewhat angularly produced in front of eyes, bearing in
front of each posterior ocellus a heavy spine (about 26 microns long),
dark except for the widely expanded apex which has sharply toothed
margins. These are the largest bristles on the head. Postocular (?)
bristles very similar (23 microns long) situated close to outer angles of
eyes and very close to lateral margin of head. A minute bristle behind
each posterior ocellus and a similar one near the inner posterior angle
of each eye. Eyes rather large, occupying rather more than half the
lateral profile of the head, each one about three-fourths the width of their
interval; dark; facets rather small.
Ocelli rather large, situated opposite anterior half of the eyes and
close to their margins, bordered by wide, dark red crescents. Mouth cone
reaching three-fourths distance across prosternum, broadly rounded at apex.
Antennae twice as long as head. Base of first segment overhung by
vertex, almost square in outline; II, oval with a short, very broad pedicel;
III top-shaped with a long, narrow pedicel, cones near apex only about
half as long as this segment, curved but not bent under segment IV;
IV broadly oval with practically no pedicel, sense cones larger than those

on III but only about half as
long as the segment; V similar
in shape but with a short, broad
pedicel; VI oblong-oval with a
short narrower pedicel, VII-VIII
a lanceolate mass with suture be-
tween the segments plainly vis-
ible, VII with short broad pedicel,
VIII sharply conical in shape,
terminal bristle very much longer
than the segment.
Prothorax (including coxae)
in width nearly twice the median
length of pronotum, which is con-
siderably larger than the head.
Setae stout and broadly capitate
similar to those of the head;
posterior marginals about 33 mi-
crons long, midlaterals somewhat
shorter, anterior laterals still
smaller, anterior marginals sit-
uated nearer the median line than
the lateral border, as long and
heavy as the marginals, coxals
nearly as long and heavy, all
straight and dark. Fore tarsus
with a tooth which is decidedly
shorter than the width of the
tarsus. Forewing without acces-
sary bristles.
Abdomen short and heavy,
segments two to six provided with
a pair of long dark, conspicuous
capitate bristles on posterior bor-
der about midway between the
median line and the lateral bor-
der. These are about as long as
those in front of the ocelli. Mid-
way between these and the lateral
border, extending also to seg-
ments 7 and 8, is a series of
more slender pale bristles, those
on segment 9 nearly as long as
tube, terminal bristles somewhat
longer than the tube. Tube a
little shorter than the head, ab-
ruptly contracted to the apex,
heavily chitinized and promi-
nently ridged. Terminal bristles
a little longer than the tube.









VOL. XXII-No. 1


Measurements of type: Head, length .12 mm., width .125 mm.; pro-
thorax, median length .14 mm., width (including coxae) .25 mm.; ptero-
thorax, greatest width .25 mm.; abdomen, greatest width .24 mm. Tube,
length .10 mm., width at base .05 mm., at apex .026 mm. Antennae, total
length .24 mm. Segments, length (greatest width): I, 21(23); II,
35(28); III, 38(23); IV, 35(26); V, 35(26); VI, 40(24); VII, 23(16);
VIII, 21(10) microns.
APTEROUS FEMALE:-Color of type similar to that of the macropterous
female; fore and middle femora largely brown but shading gradually
lighter apically, hind femora shaded with brown only on anterior margin.
Head fully as long as wide. Ocelli lacking. Otherwise very similar
to macropterous female. Measurements almost identical.
Total body length varying from .63 mm. to .92 mm. in paratypes.
Prothorax nearly .4 longer than head.
APTEROUS MALE:-Very similar in color to apterous female. Averag-
ing a little smaller, from .57 mm. to .87 mm. in paratypes. Fore femora
varying greatly in size. In the type immense, .09 mm. wide and .21 mm.
long, fully as wide as the head and longer than prothorax. Tooth on fore
tarsus very large, longer than the width of the joint, triangular in shape.
Tube shorter and wider at base than in apterous female. Otherwise
measurements very similar. In some paratypes the fore femora are
scarcely larger than in the female.
Described from three macropterous and 10 apterous females
and six males. Collected from dead leaves under live oak trees
December 15, 1935, Marion County, Florida, March, 1936, and
August, 1933, and Alachua, December 15, 1935; and from
"Spanish Moss" (Dendropogon), Alachua County, September
26, 1938; Lake County, May 12, 1933, and from scrapings from
the bark (lichens and moss) of a live oak tree, Monticello,
Florida, September 13, 1927.
Types in author's collection. Paratypes in National Museum.
This strikingly colored insect undoubtedly belongs to Sophio-
thrips, hitherto reported only from Panama, although the spines
on antennal segments III-VI are not nearly as long as described
by Hood in his characterization of the genus and do not curve
under the segments in front, and the prothorax is distinctly
longer than the head. In other characters it agrees closely with
the characters of the genus as described by Hood. Its color will
serve to readily separate it from squamosus and panamensis.

Eurythrips robustisetis n. sp.

APTEROUS FEMALE:-Body length 1.0 to 1.8 mm. Color yellowish
brown by transmitted light, dark brown by reflected light. Tarsi, distal
ends of femora and tibiae and first antennal segment (in some individuals
the second also) and pedicel of third brownish yellow; antennal segments

In its color, long setae with strongly dilated tips and the
absence of sculpture on the dorsum it resembles E. macrops
Hood but differs in the heavy dark colored setae, the large
anterior marginal ones on the prothorax, the color of the hypo-
dermal pigment, the narrower antennal segments, and the much
shorter tube.

WELCOME, ENTOMOLOGISTS
The FLORIDA ENTOMOLOGIST, speaking for the entomologists
of Florida, extends a most cordial and sincere welcome to the
members of the entomological profession of the South upon
the occasion of the meeting of the Cotton States Branch of the
American Association of Economic Entomologists at Tampa
next February 21, 22 and 23. This meeting, which is being
held under the joint sponsorship of the Florida Entomological
Society and the Newell Entomological Society, promises to be
one of the most interesting, profitable and pleasurable of the
Branch Association in recent years. The local committee have
exerted themselves to that end. The preliminary program, in
so far as scientific papers are concerned, is well rounded. The
general plans have been outlined on the basis of "all work and
no play, etc.", and entertainment features will be of such a
character as to afford adequate relief from the paper reading
sessions. Especial attention is directed to the trip on the 22nd
to the Lake Alfred Citrus Experiment Station, where state
and federal entomological workers will put on a large-scale
demonstration of spraying and dusting methods for pest con-
trol; The most highly developed methods and equipment will
be shown. This field trip will also afford opportunity to visit
the famed Bok Tower and surrounding gardens near Lake
Wales, where a carillon concert will be given. On this same
trip a large slice of Florida's citrus plantings will be seen. On









VOL. XXII-No. 1


the paper program featured speakers will present discussions
on important and timely subjects. Dr. Lee A. Strong will
discuss certain phases of the plant quarantine situation and
Professor S. C. Bruner, Entomologist attached to the Cuban
Agricultural Experiment Station at Santiago de las Vegas, has
been invited to present a paper on entomology in Cuba. E. R.
Sasscer, President of the American Association of Economic
Entomologists, will bring greetings from the parent organiza-
tion.
The annual banquet will be an informal dinner-dance held
at one of Tampa's famous Spanish restaurants. The atmo-
sphere, the setting, the food, and even the floor show will be
typically Spanish. Ample provision is also being made for the
entertainment of visiting ladies. Among other features will be
a bridge party for ladies on Monday evening, the 20th, at the
Hillsboro, headquarters hotel.
This publication is advised that the Cuban Secretary of Agri-
culture has invited the Southern Entomologists to make a post
convention visit to Cuba and observe the agricultural, especially
entomological, work being done there. Numerous courtesies
will be extended the visitors. Doctor J. T. Creighton, Chair-
man of the Committee of Arrangements, has been in touch
with officials of the P. & O. Steamship Company operating to
Havana out of Tampa and Miami, and has been assured of
especially attractive rates, including an all expense tour, for
the benefit of those attending the convention.
Again we say "Welcome", and you may be assured that the
entomologists of Florida will do all in their power to make
your visit pleasant, profitable, and one long to be remembered.
The following account is taken from the preliminary notice
of the meeting put out by the association:
"The Hillsboro Hotel in Tampa is convention headquarters
where all sessions will be held and exhibits installed. Special
rates at The Hillsboro for the convention are $2.50 and $3.00
per day for single rooms with private bath and $3.50 to $7.00
per day for double rooms with private bath. A suite of two
rooms with connecting bath for party of four can be obtained
for $1.75 per person per day. Other hotels near the Hillsboro
are as follows: DeSoto and Knox (same rate as Hillsboro);









THE FLORIDA ENTOMOLOGIST


Bayview, Lafayette, Thomas Jefferson and Park (rates lower
than Hillsboro); Floridian and Tampa Terrace (rates higher
than Hillsboro). On account of the tourist season in Florida
at the time of our meeting, reservations for hotel accommoda-
tions should be made immediately.
"Ample exhibit space has been provided in the lobby and
in large rooms at the Hillsboro Hotel. The exhibits will be a
special feature of the Tampa meetings, and those planning to
have exhibits at Tampa should contact the Hillsboro Hotel for
space.
"The meeting this year will feature citrus insects, the white-
fringed beetle, pink boll worm, sweetpotato weevil, blackfly and
plant quarantines. Special entertainment has been planned for
the ladies and delegates are urged to bring their wives and
families. This will include a special Carillon recital, visit to
Cypress Gardens, parties, tour of night clubs, etc. Low rate
steamer service from New Orleans to Tampa is available for
those coming from the western part of the Branch territory.
There is a sailing from New Orleans every Saturday afternoon
between 12 and 1 o'clock, the steamer arriving in Tampa Monday
morning between 7 and 8 o'clock. The rate is $20 one way and
$36 for the round trip."


A BRIEF HISTORY OF THE FLORIDA ENTOMOLOGICAL
SOCIETY

The Florida Entomological Society came into existence Jan-
uary 5, 1916, when eleven men interested in entomology met
at the University of Florida in Gainesville. The Entomological
News of March 1916, in noting the formation of this Society,
stated that this was the first Entomological Society organized
in the Southern States. The first officers were: President, J. R.
Watson, Experiment Station; Vice-President, Wilmon Newell,
Plant Commissioner; Secretary-Treasurer, R. N. Wilson, U. S.
Bureau of Entomology; Member of the Executive Committee,
H. S. Davis, Department of Zoology, University of Florida. The
founders must have been a very enthusiastic group of men for
the Society had a remarkably rapid growth. During the first
year it more than quadrupled its membership and by the end








VOL. XXII-No. 1


of 1917 it boasted nearly one hundred active members and
twenty associate members.
The ideals of the new Society were very simply stated as
follows: "The aim of the Society is to stimulate an active in-
terest in entomology on the part of Floridians". It is evident
that they early achieved their purpose for in 1917 a group of
twelve men in Fort Myers formed the Lee County Entomolog-
ical Society, which on January 28, 1918, became affiliated with
the Florida Entomological Society as a branch society.
Though the Society did not always maintain the large mem-
bership attained in its early years, it never-the-less has had a
continuous existence since its beginning. In December 1938
the Society petitioned the American Association of Economic
Entomologists for affiliate membership in that organization.
The petition was granted by action of the Executive Committee
at the Richmond meeting.
At the April 1917 meeting of the Florida Entomological
Society, Dr. E. W. Berger made a proposal that the Society
publish a periodical to be known as "The Florida Buggist".
This proposal was at once acted upon and the first issue con-
taining twelve pages appeared June 21, 1917. This first issue
is of particular interest at this time because it contains this
note: "March 29, 30 and 31, the Association of Cotton States
Entomologists held their meetings at the University of Florida."
Other interesting items of this issue are accounts of the early
meetings of the Society and a roll of its members.
Three volumes of The Florida Buggist were published, the
last issue under this name appearing in April 1920. At the
meeting of February 23, 1920, the Society voted to change the
name of its publication to its present name "THE FLORIDA
ENTOMOLOGIST". Since its beginning as The Florida Buggist,
the periodical has been published as a quarterly journal and
is now in its twenty-second volume. In addition to publishing
accounts of the doings of the Society and notes on insects that
are of interest at the time, the FLORIDA ENTOMOLOGIST devotes
a great deal of space to original contributions on entomological
subjects. These cover many different phases of entomological
endeavor including economic, systematic, biological, and mor-
phological studies.

THE FLORIDA ENTOMOLOGIST


THE NEWELL ENTOMOLOGICAL SOCIETY
By JOHN T. CREIGHTON

The founding of the Newell Entomological Society grew
out of a sincere desire upon the part of the students and
faculty of the Department of Entomology of the University
of Florida to contribute in a large measure of their services
to that phase of the Natural Sciences to which they had dedi-
cated their lives; while materially facilitating the advancement
and stabilization of human society.
The first meetings were held during the fall of 1935 and
the organizers were wholehearted in favor of naming the society
in honor of Doctor Wilmon Newell who is now the Provost of
Agriculture of the University of Florida.
In forming the Newell Entomological Society the founders
gave careful consideration to the constitution and by-laws. The
constitution lists the following objectives: (1) to promote the
study of entomology; (2) to encourage research and teaching
relative to insects and related Arthropods in the State of Flor-
ida; (3) to assimilate and disseminate widely knowledge of
pure science, economic, and popular entomology, to the end
that the layman shall develop a broader sense of appreciation
of the necessity for and the importance of the many phases of
the science; (4) to bring about a closer cooperation between
all entomological organizations and phases of the science; (5)
to publish a semi-annual journal to be known as RETAQ;
(6) to sponsor the annual Florida Entomological Conference.
The installation ceremony for the Newell Entomological
Society was held in February 1936, during the first annual
Florida Entomological Conference. Doctor Herbert Osborn of
Ohio State University was the featured speaker for this occa-
sion. The second annual conference was held in March 1937
at which time the Herbert Osborn birthday banquet was held.
Featured speakers were Doctor Lee A. Strong, Doctor Z. P.
Metcalf, Doctor W. S. Blatchley, Doctor E. W. Berger, and
Doctor Wilmon Newell. The third conference was held in March
1938 at which time Doctor Henry T. Fernald was honored.
Featured speakers were Doctor Dwight M. DeLong, Doctor
John J. Tigert, Mr. A. S. Madden, and Doctor H. Harold Hume.
The fourth annual Florida Entomological Conference will be









VOL. XXII-No. 1


held in conjunction with the annual meeting of the Cotton
States Branch of the American Association of Economic Ento-
mologists at Tampa, February 20-24, 1939. Past presidents
of the Society were Mr. W. P. Hunter (1935-1936), Mr. P. S.
Arey (1936-1937), Mrs. Juliet Carrington (1937-1938). The
president for the current scholastic year is Mr. James P.
Toffaleti.
There are four kinds of membership in the Society, as fol-
lows: (1) Undergraduate and Graduate students. (2) Grad-
uates. (3) Associate members. (4) Honorary members. The
graduate membership is designed to maintain a warm relation-
ship between the graduates and the department of the college
where they obtained their professional training.
Meetings are held semi-monthly, and local or out of town
speakers are invited to address the Society. Talks are not
necessarily limited to entomological subjects, but topics of a
general agricultural interest are encouraged. Attendance of
students is mandatory and unexcused absences constitute suffi-
cient grounds for recommendations by the executive committee
that offenders be dropped.
In December, 1938, the Society voted to petition the Amer-
ican Association of Economic Entomologists for affiliate society
privileges. This petition was presented by the writer to the
American Association during the annual meetings at Richmond,
Virginia, in December, and was favorably acted upon by the
National Association. This act marks the first time in the
history of the National Association that a student society has
been granted affiliation privileges. This grant immediately
focused national attention upon the Junior Society. Thirteen
graduate members of the Newell Entomological Society were
voted into active membership in the National Association.

CARLOS C. GOFF

Mr. Carlos C. Goff, Assistant in Entomology, Florida Agri-
cultural Experiment Station, and member of the Florida
Entomological Society, died on January 13, 1939, at Leesburg,
Florida, age 34 years. He was a graduate of the University
of Illinois, receiving his B. S. degree in 1928 and his M. S. in
1931. He also spent a year in graduate work at the University
of Michigan.
Mr. Goff did notable work on root-knot, and on the life
history of "salamanders" and "gophers".
He suffered a severe blow in February, 1937, in the death
of his wife, who was also a graduate of the University of
Illinois (see FLORIDA ENTOMOLOGIST, Volume 20, No. 1, page
5). He leaves a daughter, Eva, parents, and a brother and
sister.
Mr. Goff was a very tireless worker, a very agreeable and
lovable and promising young man. The Florida Experiment
Station, our Society and science in general suffers severely in
his untimely death.
Between 1927 and 1930 he served as assistant in entomol-
ogy in the Natural History Survey in Illinois. He was a
member not only of our Society but of the American Society
of Mammalogists, Ecology Society of America, and the Amer-
ican Society of Ichthyologists and Herpetologists, the Wild Life
Society, and the Florida Academy of Science.
This and the following list of his publications shows his
wide interests.

A CORRECTION
In the last number of the ENTOMOLOGIST, Volume 21, No. 4, page 62,
"A Remarkable Flight of Butterflies", a mistake crept in. The estimate
of abundance was one butterfly per cubic yard of space instead of a
cubic foot as given in the article.
