168 ; ibid. II, 109, G03. 



Oblong, rather robust. Antennae, bead and thorax piceous, bronzed; 

 densely clothed with fine yellowish hairs; elytra and under parts dull red- 

 dish-brown, more sparsely pubescent; legs and two basal joints of antenn:i> 

 paler. Third joint of anlenn:e twice as long as second, shorter than fourth. 

 Thorax as wide at base as long, narrower in front ; sides feebly rounded ; 

 disk finely and densely punctate; hind angles divergent, not cariuate. Ely- 

 tra slightly widest behind the middle, then strongly attenuate to acute tips; 

 striae with indistinct punctures ; intervals subeonvex, minutely punctulate.

XLII. ASAPHES Kirby. 1837. (Gr., "obscure.") 



Differs from Corymbiies only in the structure of the tarsi which 

 have the first joint as long as the next two together; the second and 

 third joints each dilated beneath into a short spongy lobe; fourth 

 joint small and narrow, received upon the third ; fifth joint elongate 

 with simple claws. The known North American species are. treated 

 in the following paper : 



Horn. "Notes on the Species of Asaphes of Boreal America," 

 in Trans. Amer. Ent. Soc., VIII, 1880, 69-75. 



Three species have been taken in Indiana, while two others prob- 

 ably occur.
