TYLOTHRIPS BRUESI, 
A NEW THYSANOPTERON FROM FLORIDA 
By J. Douglas Hood 
Cornell University 
The following species was taken within a few miles of 
Professor Charles T. Brues’ home on the St. Johns River, 
in Florida, shortly after we had collected together and 
renewed an acquaintance which apparently began very 
nearly fifty years ago, long before he became Professor 
of Entomology at Harvard University and Editor of 
Psyche. 
Tylothrips bruesi, sp. nov. 
Text-figures 1 to 3. 
Like the Peruvian concolor Hood, the type of the genus 
and only known congener, in coloration and most structural 
features, but (1) head about 1.4 (instead of scarcely 1.2) 
times as long as width across eyes, (2) last two antennal 
segments much narrowed basally, thus not forming with 
segment vi a terminal club, (3) segment in of antennae 
longer (instead of much shorter) than IV, and with several 
of its more apical setae as long as the neighboring sense- 
cones, (4) fore tibiae, only (instead of all three pairs), 
tuberculate along inner surface, (5) tube fully 2.3 (instead 
of less than twice) as long as its greatest subbasal width, 
and (6) major setae dull, or blunt, or very slightly dilated 
at tip (rather than broadly expanded). 
2 (macropterous) . — Color of entire body, legs, and 
antennae blackish brown, with pedicel of antennal seg- 
ment in and tip of tube somewhat paler and yellowish, 
IV-VI narrowly whitish just beyond the dark extreme base; 
internal pigmentation bright crimson-red, abundant in 
thorax and abdomen (exclusive of tube), sparse in head 
and first antennal segment; fore wings brown, darkest in 
anal area and with a dark median streak, which is nar- 
rowly edged with paler, extending to tip, the posterior 
margin pale between anal area and first fringing hair;
