This and the two preceding species agree so completely in 

 general colour, form, and sculpture, that it will be only necessary 

 to give the points of difference : — 



In P. Papuana the antennae are entirely rufo-testaceous ; the 

 colour of the darker portion of the elytra, which is violaceous, varies 

 greatly in extent, sometimes covering only the hinder two-thirds 

 of the elytra, in other specimens extending over the whole surface, 

 leaving only a narrow space at the basal margin ; the hinder thigh 

 in the $ of the same species has a strong conical spine. 



In L. Boisduvalii the outer half of the anteimae is black ; the 

 colour on the elytra is bright cyaneous instead of violaceous, and 

 less variable in extent, occupying usually rather more than two- 

 thirds of their surface; and the femoral spine of the $, thou<di 

 equally long, is less robust and slightly curved at its apex. 



The S of L. connectens may be known from either of the 

 other two species by the much shorter spine on the hinder femora;
