Hab. Philippine Islands. B.M. 



I am only acquainted with a single very mutilated spe- 

 cimen of this species in the National Collection. The ab- 

 domen is broken off at the third segment, but the whole 

 form of the insect seems to indicate it to have been a male. 

 It is long, slender, subcylindrica], entirely dark brown ; 

 the head, pro- and mesothorax finely granulose on the 

 upper side. The head is destitute of ocelli ; it is subovate, 

 with the eyes moderately ])rominent. The tegmina are 

 small and obovate, obliquely truncate at tlie tips ; the ca- 

 rina is but moderately and gradually elevated near the base. 

 The wings are of moderate size, pale brown, with the costal 

 area dark brown, the base jiale buff. The legs are mode- 

 rately long and slender, destitute of spines or lobes. The 

 abdomen is slender, cylindrical, and smooth ; the six ter- 

 minal joints broken off.
