This species can only be distinguished from the common 

 E. qnadriguttatus, III., by a careful examination of the 

 secondary sexual characters. In size, shape, and coloration 

 it agrees exactly Avith it^ but the male has the front tibia a 

 little bisinuated, with the tooth stouter and more promi- 

 nent, the abdomen is without the pad of dense erect hairs 

 occupying the middle of the two terminal segments beneath, 

 and the last ventral segment is much less deeply emarginate 

 at the apex. The female has the extremities of the elytra 

 less produced, and the apex of the abdomen is without the 

 triangular excision found in that of E. qnadriguttatus. There 

 is an even closer relationship between this species and the 

 Malayan E. sybarita, Gerst., but our form is a little smaller, 

 less glossy above, and decorated with smaller spots, the 

 posterior ones being separated by an interval about twice 

 the diameter of each, whereas in E. sybarita it is of about 

 equal diameter. ^J'he male has the front tibia more 

 slender, the tooth less stout, and not followed by a distinct 

 emargination.
