the middle, while in L. foliaceus the expansion is nearly oblong- 

 ovate and widest in the middle. 



5 . Differs only from the female of L. foliaceus in having the 

 black at the apex of the elytra straight in front. 



Mr. Murray states that the female of his L. immersus is L. ccan- 

 thomelas, Dalm., and there seems to be little doubt that this is 

 correct. Under these circumstances it appears better to adopt the 

 older name, although only originally applied to the female.

Still smaller than L. xanihomelas, with the black at the apex of 

 the elytra continued along the sides to about the middle.

Allied to L. xanthomelas, but very distinct from its allies on 

 account of the suture of the elytra about the middle being conically 

 elevated. 



There is a specimen in the Museum collection from Angola which 

 differs from the type in having some yellow in the middle of the 

 black apical half of the elytra ; the disk of the thorax is also more 

 distinctly fuscous.

Not unlike the female of L. foliaceus, but the disk of the thorax 

 is black, and the posterior angles are more acute. The eljiira are 

 roughly punctured and are less parallel, the second costa is very
