prothorax above is shaded with dark olivaceous and brownish,

Belongs, with the following species, to the second N. A. 

 Group of the genus, containing C. nechus, C. porcus, etc., and 

 resembles distantly C. anubus, Cramer sp. from Surinam. It 

 resembles the description of C. nitidula, Clemens, but differs 

 in detail. There are no lateral caputal and thoracic linear 

 discolorations, nor an abdominal " double row of dark brown 

 dots." No mention is made in the description of C. nitidula, 

 of the very distinct irrorations which characterize C. laevis, 

 in which latter species the very distinct black angulate oblique 

 linear band, emanating from costa at apical fourth, is a promi- 

 nent feature ; the presence of this band in C. nitidula, is denied 

 by the italicized expression " a single brownish line from the 

 inner margin to the tip ;" the corresponding line with this 

 latter in C. laevis is plainly olivaceous. It is to be regretted 

 that no measurements are given by Dr. Clemens of either C. 

 nitidula or C. versuta, species which are somewhat incomplete- 

 ly illustrated, and of which the types appear to be now lost, a 

 circumstance much to be deplored.
