It is very possible that gracilis may be referred to synonymy 



under sobrinus, when these apparently plastic species are better 



known.

The male here recorded has the fastigium of the vertex of no 

 greater length than in males from Sumatra assigned to E. gracilis 

 (Redtenbacher). In the present male, however, it is distinctly 

 more slender and fully as acuminate as in the Javanese female 

 before us.

CONOCEPHALUS (Thunberg) 



Chloroxiphidiox new subgenus 



In 1915, Rehn and Hebard published a key to the subgenera of 

 the genus Conocephalus}- Little work has been done on the genus 

 from that portion of the World here under consideration and we 

 are not surprised to find an undescribed subgenus represented by 

 certain species from Australasia and Malaysia. 



Type of subgexts — Conocephalus (Chloroxiphidion) javanicus

Prosternum bispinose. Caudal tibiae armed at distal extremity 

 with two pairs of spurs, the ventral pair being absent. 83 Ventral 



82 Trans. Am. Ent. Soc., XLI, p. 226. 



83 The dorsal pair of spurs are, moreover, greatly reduced, no larger than the 

 spines of the dorsal margins of the caudal tibiae and only differentiated from 

 them by having a basal socket.
