Mr. Murray states that the Female of hie />. immersus is L. xan- 



thotn leu, Daun., and there Beems to he little doubt that this is 



oorreet Under these eiroamstancea it appears better to adopt the 



older name, although only originally applied to the female.

Still smaller than L. .rantJwmelas, 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

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