The infuscation of the seriate punctures on the elytra causes 

 those organs to appear to a casual glance striped with a number of 

 brownish lines. This species is near R. cicatricosus, Chp., (a 

 species that I think I have correctly identified), but differs from 

 it, inte7' alia, by the very much less close jDuncturation of its 

 prothorax.

(J. Sat nitidus ; ruber, prothorace indeterminate nigro-notato, 

 antennarum tibiarumque apice summo tarsorum articulo tertio

 prothorace grosse ruguloso, quam longiori fere duplo latiori, 

 angulis anticis minute acutis vix dentiformibus ; scutello
