Colour dark chestnut-brown. 



Texture rough and dull. The roughness is upon the epiostracum, which 

 is easily detachable in parts, and is consequently apt to rub off partially. 



Cephalothorax large, rather more than half the length of the abdomen, 

 broadly conical. Rostrum rounded at the tip. Rostral hairs short and curved 

 inward. Lamellce extremely large and almost horizontal, joined anteriorly by a 

 translamella, also horizontal, which is continuous with the lamellae, and not 

 distinctly demarcated from them ; both are formed of light translucent chitin ; 

 the whole together cover the larger portion of the cephalothorax. Cusps of 

 the lamella very large, projecting nearly as far as the tip of the rostrum ; 

 very broad, and deeply excavated anteriorly for the insertion of the lamellar 

 hair, which is thick, long, and curved inward ; those from the two sides 

 generally cross. The lobe of the cusp outside the hair is generally rounded, 

 the inner lobe pointed, but the chitin of which they are formed is thin and 

 brittle, and the inner lobe, as well as the outer, is often rounded in captured 

 specimens ; the outer lobe may possibly also be pointed when the creature 

 emerges, but this cannot probably be ascertained without rearing the creature. 

 Pseudo-stigmata large, of thick rough chitin, almost hidden between the 

 lamella and the wing-like projection from the abdomen. Pseudo-stigmatic 

 oro-ans rather long, moderately recurved, with slightly fusiform heads upon 

 thin peduncles. Inter-lamellar hairs rod-like, slightly curved, not conspicuous ; 

 each is mounted upon an almost circular chitinous ridge. Tectopedia large 

 and conspicuous from the dorsal aspect. 



Legs of moderate length ; the fourth pair pass the hind margin of the 

 abdomen by about half the length of the tarsi. The femora of the first pair 

 have slender peduncles to suit the deep cleft in which they are inserted ; the 

 other femora are without peduncles. The coxse of the fourth pair of legs lare 

 pyriform, flattened, curved backward, and drawn out to a long curved point 

 outside the lateral edges of the femora ; the whole coxa thus assumes the form 

 of a comma, or of one of the ornaments known as "pines" in Indian 

 embroidery. Claws large and monodactyle. The tarsi bear numerous fine 

 hairs, and there are a few similar hairs on most of the other joints. 



* Named in lionoui- of the memory of the discoverer.
