Long. (cap. excl.) 29 mm., rostr. lU, elytr. 13, lat. 13. 



From tbe otber cyrtotraelieloid species of Omofemii/ts this form differs cbiell}' 

 iu the form and sculpture of the rostrum of both sexes, and in the strongly 

 convex prothorax of the ///ale. 



Hall. Assam (Khasia Hills) and Upper Burmah (Ruby Mines). 



One 1/iali; specimen from North India, jjrobably from Sylhet, has the 

 prothorax rather more convex, and the pygidium much more densely punctured 

 at the sides than along the middle ; the j)unctuation on the sides of the second 

 abdominal segment is also coarser and denser than in typical specimens. 



In one female example from the Khasia Hills (Assam) the base of the 

 trunk is as sparsely punctured on the sides as on the upperside. 



These two forms are only aberrsitions, I believe, of the above-described 

 species, with which they agree in all other characters.
