77. Species metallic or submetallic 78 



Species not metallic ; head and thorax opa(iuc or subopaque. alutaeeous, ehisely microscopieally punc- 

 tate or shagreened, and pubescent. 



Postmarginal vein present. 



Pedical longer than the first joint of funicle ; flagellum clothed with hairs, the funicle 

 joints, except the tir.st two or three joints, not or scarcely longer than thick.

 elongate, cylindrical, and clothed with sparse, long haiis. .. . Heterarthrellus Howard. 

 Postmarginal vein wanting. 



Pedicel as long as the first funicle joint ; flagellum subclavatc, the club not quite so long 

 as funicle joints 4-C united, first joint of funicle the longest, the following gradually 

 shortening, clothed with a short, rather dense pubescence Astymachus Howard. 



78. Thorax without a scaly pubescence, and without white lunuhe before the tcguhe 79
