of segment 2, and there are several sense hairs and a pronounced sense 
pit at the tip of segment 4 (Text-fig. b). Whole head pale translucent 
yellowish brown, which is the general color tone of the whole body. ' 
Spots of darker opaque brown indicate the special chitinization of 
mouth parts, etc. 
Prothorax large, longer than the head and with conspicuous ex- 
panded lateral margins or wings, and covered all over with strong 
spiny hairs some of them, especially those of the lateral and posterior 
margins, very long. Ventral face also with long spiny hairs. Meso- 
thorax smaller than prothorax, being little more than half as long, 
although quite as wide. (N. B.—In Text-fig. a the mesothorax is too 
long.) It is abundantly supplied with spine-hairs, a very long one 
arising from each postero-lateral angle. Metathorax distinctly set 
off from mesothorax by suture, but smaller and resembles an abdominal 
segment in general shape and appearance. Its numerous spine-hairs 
are disposed as those of the abdominal segments are. The general pale 
translucent yellowish brown of the thoracic segments is patterned by 
the showing through of the darker chitin rods of the ventral aspect and 
endoskeleton. 
Legs (Text-figs. c, d, h, g) rather long and strong, and very spiny, 
especially the third pair. The distal ends of the tibiae of this pair are 
furnished with a conspicuous group of short stout spines, while a less 
conspicuous group occurs also on the ends of the second tibiae. The 
legs are concolorous with the body. 
, The abdomen of the male is broad and only a little longer than head 
and thorax combined. In the female the abdomen is less broad and is 
also longer, giving it a decidedly more slender appearance. The entire 
abdomen, both on dorsal and ventral aspects, is thickly beset with long 
spiny hairs, those rising from the lateral margins (especially of the 
hinder segments) being very long indeed. The hairs on the dorsal 
aspect are disposed in two transverse series, but rather irregularly. 
The hairs of the hinder series of the two are longer than those in the 
front one (Text-fig. f). Posterior margin of abdomen in both male and 
female simply and broadly rounded, that of the female (Text-fig. e) 
with numerous fine hairs in close series at the lateral margins, while 
that of the male has the strongly-chitinized, unusually shaped genitalia 
either projecting or, if retracted, showing through rather plainly.
