Eighth joint of antennae elongate ....olbsCUI'lIS 



Eighth joint slightly transverse, and much shorter than the seventh. 



obtusiis 

 Elytra higlily polished, not reticulate ; very minute species. 



nanulus 

 Punctures of the second and third series from the discal stria composed of 

 punctures which are large, deep and distinct in the middle third, but 

 obsolete toward base and apex. 

 Lateral series composed of very minute, nearly obsolete punctures. 



pusilliis 

 Lateral series composed of widely dilated, crescentiform punctures.

Discal stria very short and feeble, not extending beyond the middle : body

Discal stria normal, obsolete at basal third ; body attenuate behind from 



the base of the elytra.

Punctures very feeble ; metasternal process very wide, the mesosternum

Punctures distinct and rather distant ; metasternal process narrow, 

 • shorter, the mesosternum before it long, rather narrow and flat. 



atteniiatus 

 Elytra more coarsely reticulate in transverse wavy lines ; color intense 

 black above ; punctures of the series rather close and very deeply im- 

 pressed throughout the width elongatlllus
