This species differs from E. moorei ^ the onl}^ other S3^mmetrical 

 species of the genus known, in having six instead of five well- 

 developed antennal lamellae, all somewhat short and stout. The 

 cephalic ridges between and in front of the frontal tubercles are absent. 

 The frontal tubercles are situated as in Episphenus, not as in 

 Tiheriodes (also S5^mmetrical) from Assam and adjoining the hills. 

 The central tubercle is more strongly elevated than in E. nioorei, 

 with shorter parietal ridges. The punctures and hair on the lower 

 surface of the prothorax are very feebl}" developed. The large 

 punctures on the posterior intermediate areas of the metasternum 

 are somewhat shallower than in E. moorei, and the puncturing of 

 the grooves on the elytra is less coarse.
