acute and prominent, and the shoulders are laterally expanded, the 

 base of the fourth costa forming the edge of this expansion. 



Mr. Murray described this specimen as a female ; it is, however, 

 undoubtedly a male.

S . Very close to L. latissimus, L., but besides the absence of the 

 lateral black spot on the elytra, it differs in having the apex of the 

 elytra less broadly truncate, and the lateral expanded portion is 

 more inflated towards its base. 



2 . The female difiers from that of latissimus in having the costa 

 at the shoulder of the elytra less elevated and less semicircular in 

 outline.

Extremely close to L. latissimus, and only to be distinguished by 

 the black at the apex of the elytra, the inner margin of which is 

 parallel to the line of the side and is not suffused at the apex. The 

 male has the apex of the elytra perhaps a little less broadly truncate, 

 and the female has the costal ridge less elevated.
