 pubescens, antennis articulis 3 — 11 pedibusque (femoribus partim 

 nigris exceptis) obscure rufis ; elytris fasciis angustis tribus, Ima 

 paullo ante, '2nda paullo post-medium, 3ia ante apicem (in maculas 

 quatuor divisa), maculaque suturali ante fasciam primain, cinereo-

Hah. Mexico, Omilteme, alt. 8000 ft., Chilpancingo, 

 alt. 4G00 ft., both in Guerrero (H. H. Smith). 



Closely allied to O. viridiventris (Chevr.), and scarcely 

 distinguishable from it except in the very different colour 

 of the pubescence which clothes the upper surface. It 

 belongs, with 0. viridiventris, to a section of the genus in 

 which the posterior-divergent discoidal carinae of the 

 elytra are barely perceptible, and the apices without 

 truncature. All the specimens I have seen from Guerrero 

 are alike in the black upper surface and cinereous elytral 

 belts. In O. viridiventris the colour is ochreous. 



Ochresthes clerinus, n. sp. (PL VI., fig. 13).

hoc perparum rotundato. Niger, si;btus dense ciuereo-pubescens, 



capite thoraceque obscure griseis, antennis (scapo fusco excepto) et 



pedibus fulvo-rulis ; elytris ad apicem singulatim rotundatis, sutura
