with the body reddish beneath I believe to be more or less im- 

 mature. I do not observe any good sexual characters, beyond 

 that the males seem to be a trifle smaller and of m.ore parallel 

 form than the females. The species is somewhat unusually 

 nitid among the Heterom/ces. It bears much resemblance to 

 H. safelles, Blackb., which, however, i?iter alia, has very 

 much shorter hind coxae.

In general appearance and sculpture this insect looks 

 like a dwarf of II. AlpicoJa, Blackb., but differs inter alia 

 in its prothorax evidently less transverse, its colouring, and 

 especially in the peculiar structure of its elytra, which be- 

 come suddenly depressed a short distance before the apex, 

 looking when viewed from above as if the extreme apical 

 part became abruptly less thick than the rest of the elytra. 

 I believe my two examples of this species to be male and 

 female, the elytra of the female reddish-brown, those of the 

 male nearly black. I do not find any notable sexual difference 

 (unless that of colour be sexual) except in the evidently flat- 

 ter abdomen of the male.
