it in size, colour, and general details, will not, I think, prove to be distinct. The sex 
is uncertain ; the fifth and sixth segments are quite simple, but the latter projects 
beyond the apex of the elytra.

Head finely but distinctly punctured, with a double impression between the eyes, 
behind which it is black; the mouth is yellow, with the exception that the tips of the 
maxillary palpi, the terminal joint of the labial palpi, and the inner edge of the man-
