Hah. Burma : Haka, Chin Hills (F. Venniny). 



This has the form of E. hardwickei and E. coelestinus, as 

 well as the angularly prominent crests at the shoulders, 

 but it is rather smaller, the elytra are quite sliining, except 

 at their hinder extremities, and the club of the antenna 

 is less dilated, more loosely articulated and more asym- 

 metrical. The hind angles of the pronotum are a little 

 more sharply produced. The coloration is practically the 

 same as in E. coelestinus. 



The male has the abdomen excavated in the same way, 

 but with the lateral ridges more sharply elevated, and the 

 tibiae are more regularly curved. 



Eucteanus vicinus, sp. n. 



Violaceus, elytris nitidis, utroque bimaculato, macuhs magnis, 

 palhde flavis, subrotundatis, ad margines interuam et externam
