appear r to be somewhat abraded. It is manifest however that 
the whitish pubescence clothes the head and pronotum somewhat 
evenly. On the elytra the pubescence is interrupted by small 
patches of darker colour showing (in the examples before me) 
the derm, but I suspect that in a fresh specimen the dark spots 
are clothed with pubescence of the colour of the derm,—as I find 
some indication of such pubescence on some of the spots.

The shape of the insect for which I found this genus (with its 
strongly convex oval elytra, somewhat suggesting the thought of 
Ohorkynihii) ) together with the metallic gloss of its surface, 
renders it very easy of identification. In Lacordaire 
tion it falls into the “Groupe” Tropiderides by virtue of the 
following characters :—Antenne inserted in the sides of the 
rostrum, ante-basal carina of pronotum present, rostrum short 
flat, and at base not narrower than the head, rostral scrobes 
foveiform, eyes entire, sides of rostrum sub-parallel. Its struc- 
tural characters seem to place it near T’ropideres, from which it
