Hah. Espirito Santo, Brazil. 



Two exactly similarly coloured specimens of this species are 

 before me ; the design of the elytra difters from that of any other 

 Oedionychis, and the general size of the insect is comparatively 

 small. 



OeDIONYCHIS VENEZUELEl^SIS, Sp. 11. 



Flavous, the apical joints of the antennae jDiceous ; head with

 middle, black.

Diflfers in the coloration of the head and the })Osition of the
