 about as broad as the head and about as long as broad ; anterior 

 margin truncate, posterior margin broadly rounded, black, the 

 sides yello\^ish. Elytra ample, smooth, well rounded at the 

 shoulders, tapering posteriorly, black, with an ill-defined, often 

 obsolete, reddish spot, very variable in size, at the shoulder angle. 

 AVings long, black, with a yellowish stripe down the suture. 

 Legs long and slender, blackish, the base of the femora, apex of 

 the tibise, and the tarsi yellowish. Abdomen black and slender at 

 the base, strongly dilated about the middle, decidedly convex and 

 tapering towards the apex ; sides of the segments unarmed.

 slender, black, strongly sloping and decidedly narrowed posteriorly, 

 especially in the female ; posterior margin straight, tumid over 

 the roots of the forceps. I'orceps of both sexes with the branches 

 slender , cylindrical, black, contiguous at the base ; in <5' straight ; 

 seen from the side, curved gently upwards in the basal third, at the 

 end of which, on the upper surface, there is a long, strong, sharp,

The slender build and peculiar forceps easily distinguish this 

 elegant little earwig. It is only likely to be confused with 

 E. hurri, Bonn., Mhich is common throughout the Malay Archi- 

 pelago, but has not yet been recorded from India, though it will 

 probably be discovered in Burma. E. hurri is a little larger, but 

 the coloration is the same and the forceps are very similar; 

 there is this difference, that in E. hurri the branches are quite 

 decidedly arcuate and have a sharp tooth on the inner margin 

 at the base of the oval enclosed area. 



The females of these two species are practically indistinguishable.
