TEGEOOEANUS HEEICIUS. 347 



not large; pseudo-stigmatic organs almost -upright, 

 with peduncles of moderate length, and large, shortly 

 pyriform, rough heads. Interlamellar hairs rod-like, 

 somewhat curved. Tectopedia very large and promi- 

 nent, particularly the first pair. Opisthophragmatic 

 processes very small. 



Legs of moderate length, the fourth pair slightly 

 passing the posterior margin. Femora of the first 

 pair with slender peduncles, genuals of two front pairs 

 rather long. Tactile hairs on first pair of legs only ; 

 tarsi with the usual fine hairs, other joints with a few 

 curved hairs. 



Abdomen oval; progaster rounded and distinct. 

 The whole edge, except the progaster, is broken up by 

 very strong, rough projections hearing stout sharply- 

 curved hairs. Thenotogaster is not much arched, and the 

 edge is slightly curved upward, but the ornamentation 

 is the same over the ivhole notogaster, there not being 

 any different band round the edge. This ornamentation 

 consists in a number of very strong, rough ridges 

 forming a coarse and very irregular reticulation, with 

 remarkably deep pits between the ridges ; the bottom 

 of these pits is granular. Heticulations average about 

 forty to the millimetre. Genital and anal plates near 

 together, the former square, the latter pentagonal. 



Nymph. 



This is a very beautiful and extremely elaborated 

 creature (in external appearance), in fact one of the 

 most so in the family. 



Colour light whitish-brown or drab; legs and rostrum 

 slightly darker reddish-brown. 



Shape elliptical; the ellipse becomes broader at each 

 change of skin ; the edge is rough and broken by granu- 

 lations. 



Cephalothorax small, conical. Rostrum blunt. Ros- 

 tral hairs fine ; on the dorso- vertex are some ridges
