pleasure in naming- one of the species for Mr. Smith. I am 

 also greatly indebted to Prof. Forbes for numerous courtesies 

 and privileges. 



Genus TRICHOTHRIPS Uzel, 1895. 

 Trichothrips smith! sp. nov. 



Figs, i and 2. 



Female Forma aptera. Length about i mm. General color (by trans- 

 mitted light) yellowish brown, with maroon hypodermal pigmentation; 

 tube pale yellow, tipped with gray; tarsi and antennal segments I and 2 

 pale yellowish, the latter darkened laterally with blackish brown. 



Head fully as wide as long; cheeks sub-parallel in basal half, anterior- 

 ly converging to eyes ; dorsal and lateral surfaces sparsely and briefly 

 spinose, faintly striate ; postocular bristles slender, pointed. Eyes re- 

 duced, about three facets forming the lateral profile. Ocelli wanting. 

 Antennae stout, about twice as long as head ; segments I and 2, and 

 base of 3, pale yellow, shaded with darker; remainder of antenna dark 

 blackish brown; segment 3 sub-conical; 4-7 sub-globose, pedicellate; 8, 

 lanceolate, pedicellate; sense cones slender; formula* 3, i-i ; 4, i-i ; 

 5, i-ixi ; 6, i-ixi ; 7 with one on dorsum near apex. Mouth cone 

 short, reaching about two-thirds across prosternum; labium broadly 

 rounded at apex; labrum narrowed apically; just attaining tip of labium. 

 Prothorax about as long as head, and (including coxae) about twice 

 as wide as long; all spines present, rather short, sub-acute. Pterothorax 

 about as long as, and slightly narrower than, prothorax. Wings want- 

 ing. Legs about concolorous with body, excepting tarsi and apices of 

 tibiae, which are pale yellowish ; fore tarsi armed with a small acute 

 tooth. 



Abdomen slightly wider than prothorax, narrowing roundly from 

 segment 5 to base of tube. Tube about .6 as long as head, and slightly 

 more than 1.4 times as long as its basal width; terminal bristles longer 

 than tube. 



Measurements : Total length T.o mm.; head, length .155 mm., width 

 .158 mm.; prothorax, length 1.47 mm., width (including coxae) .30 mm.; 

 pterothorax, width .28 mm. ; abdomen, width .33 mm. ; tube, length .09 

 mm., width at base .063 mm., at apex .033 mm. Antennae: I, about 25^; 

 2, 46^ ; 3, 49^ ; 4, 42^ ; 5, 42^ ; 6, 41^ ; 7, 3^ ; 8, 43/u, ; total .32 mm. ; 

 width 



*In the formula for the antennal sense cones, the number of the 

 antennal segment is followed, first, by the number of sense cones on 

 its inner surface, and then by the number on its outer surface; rudi- 

 mentary cones are expressed by an exponent preceded by a plus sign. 

 Thus 5, i - ixi means that on the fifth antennal segment thrrc is one 

 fully developed sense cone on either side, with an additional rudimen- 

 tary one on the outer surface.
