DIOCHUS.—AGRODES. 467 
shining, of a dilute piceous colour, with four punctures placed near one another on the 
middle behind, and with five other punctures on each side. Elytra shorter than the 
thorax, shining, with but few punctures. Hind body quite dull, very densely and 
finely punctate, fusco-piceous ; the segments ferruginous behind, and more broadly so 
at the extremity. 
This species differs from D. nanus by its larger size and much larger antenna, these 
being both longer and stouter. Five examples in all were secured; the one figured 
was found at Pefia Blanca.

This species is very closely allied to D. schaumi, but is slightly smaller and of darker 
colour, with a narrower head and rather more feeble antenne; the elytra are a little 
longer, and the punctuation of the hind body is not quite so dense and fine. 
Only two examples were met with.

This genus is no doubt confined to the regions of Tropical America, where specimens 
of four species have been procured, two being from the valley of the Amazons.
