CICIJs DELIDvE. 



pronotum is considerably shorter and more ample than in the 



male) ; collura slightly rugose, hinder 

 part smooth with a very fine central 

 Jine; elytra much narrowed in front, 

 strongly gibbose behind, rugose to- 

 ward apex, and with the sculpture 

 behind forming more or less long 

 and regular furrows which become 

 very irregular at the sides and 

 obsolete at the apex ; legs red, apical 

 portion of tibiae and the tarsi black. 

 Length 11—12 millim.

In the male the head is slightly more 

 excavate between the eyes, the dilated 

 portion of the pronotum is narrower, 

 and the longitudinal sulci of the 

 elytra are more regular ; the pro- 

 notal collum is very distinct in 

 both sexes. It is possible that in 

 a long series these differences may 

 Derocrauia honorei. be found not to be sexual.

Closely allied to I), honorei, and especially resembling the male 

 of that species, from which it differs in having the head smaller 

 and the forehead flatter between the eyes, and both the collum 

 and the posterior part of the pronotum longer and narrower ; the 

 collum is strongty constricted and cylindrical and more evidently 

 plicate transversely, and the hinder part is more parallel and 

 gibbose ; the basal portion of the elytra is narrower and more 

 deeply and granulately punctured, and the inflated part behind 

 is much more deeply and regularly sulcate longitudinally, the 

 sulci beginning nearer the base, and being continued nearly to the 

 apex ; the six or seven median sulci are quite regular and parallel, 

 and the lateral ones are about the same as the discoidal ones in 

 D. honorei ; the general colour of the insect is blacker than in the 

 last-named species. 



Length 11 millim.

Mr. H. L. Andrewes has taken this species in the Nilgiris 

 (4500-6000 ft.) in April, May and June, by beating. He states 

 that it closely resembles an ant, runs very rapidly, and has an 

 offensive odour.
