Prothorax .8 as long as head and (inclusive of coxae) twice as long as 

 broad ; all usual bristles present, capitate, subequal in length, about as long as 

 the postoculars. Pterothorax slightly wider than prothorax, widest at middle, 

 thence converging slightly to each end. Legs stout, concolorous with body ; 

 fore tarsus with stout tooth. Wings pale yellowish, broad, about ten times 

 as long as the breadth at middle, not constricted ; 4-6 accessory hairs on the 

 hind margin of fore wing. 



Abdomen large, a little wider then pterothorax ; dorsal bristles capitate, 

 ventral laterals pointed, all terminal bristles pointed. Tube very heavy, .84 as 

 long as head and only half again as long as the basal width, which is 3.7 

 times the apical ; surface covered with several irregular rows of small seta- 

 bearing warts ; terminal bristles short, about half the length of the tube. 



Measurements of holotype : Length 1.68 mm.; head, length 0.228 mm., 

 width 0.216 mm.; prothorax, length 0.180 mm., width (inclusive of coxae) 

 0.362 mm. ; pterothorax, width 0.372 mm. ; abdomen, width 0.432 mm. ; tube, 

 length 0.192 mm., width at base 0.125 mm., at apex 0.034 i""^- 



Female, forma brachyptera. — Apart from the reduction of wings and 

 pterothorax, and a slight reduction in the size of the eyes, this form does 

 not differ from the fully winged one. The ocelli with their red pigment are 

 quite distinct. 



Male (brachypterous). — Smaller than the 'female (length 1I4 mm.). 

 Fore femora slightly more swollen and tarsal tooth larger. Prothorax only 

 1.8 times as broad as long. 



Measurments of allotype: Length 1.38 mm.; head, length 0.192 mm., 

 width 0.176 mm.; prothorax, length 01.80 mm., width (inclusive of coxae) 

 0.329 mm.; pterothorax, width 0.306 mm.; abdomen, width 0.372 mm.; tube, 

 length 0.186 mm., width at base o.iio mm., at apex 0.036 mm. 



Described from 4 macropterous females, 4 brachypterous females, 

 and 4 brachypterous males taken " in body of orange tree," Orlando, 

 Florida, January 21, 1913, by W. W. Yothers. 



This species comes nearest to Trichothrips anoniocerus Hood but 

 may be separated from this by the much more sw^ollen tube, the almost 

 complete fusion of the seventh and eighth antennal segments, the
