L. foliaceus, or straight as in L. semiamplexus, or rounded in- 
curved as in L. dentipes. | 
The female specimens seem most of them to correspond with 
this in size, and came along with them and in equal numbers; 
therefore I have presumed them to be the female of this, rather 
than of the typical L. foliaceus. Fig. 2 represents one of these 
females. They are the L. xanthomelas of Schénherr.

Allied to LZ. emmersus. Elytra in the male distinguished 
by a prominent dorsal umbo. The apical black patch extends 
over fully the half of the elytra, and embraces the umbo. The 
suture is incurved and slightly sinuate at the apex, and has 
the angle blunt. 
Only one specimen was received.

— g. Still smaller than L. emmersus, and very constant in size ; 
rounder behind than it. The reticulations are finer, smaller, 
and the texture rather closer; and the form of the black apical 
mark on the elytra is different, extending in a well-defined 
narrow band more than halfway along the outer margin, and 
also encroaching in an oblong patch on the suture, as shown 
in Pl. IX. fig. 6; in other respects the colouring is the same. 
The suture is straight, and its angle right-angled and a little 
rounded or blunt at the point (fig. 6). 
I have no doubt that this is distinct from any of the pre- 
ceding; the size, distribution of colour, straightness of the 
suture, and fineness of texture are very constant. I have, 
however, no certainty about the female.
