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. /). 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.
