 subangusti. Pro- et mesu-stcrna ut in Coptope. 

 The form of the prothorax, in conjunction with the normal 

 proportion of the length of the scape to that of the third joint of 

 the antennae, and the non-unguiculate apex of the last joint, will 

 readily distinguish this genus from Coptops ; while the rounded 

 prosternum, inter alia, separates it from Clyzomedus. The three 

 species are on the whole tolerably homogeneous in point of form ; 

 in size, judging from the few specimens before me, there is a 

 little discrepancy.
