 posterior angles rounded, base impressed on each side of the 

 longitudinal median groove, the impressions punctured ; elytra 

 elongate, subparallel, slightly broader than the prothorax, deeply

 iridescent ; the shape of the prothorax is the same, but the elytra 

 have no basal sutural depression ; legs, palpi, labrum, and the two 

 basal joints of antennae fiavescent, the other joints slightly infuscate.

 Eev. Zool., 1876, p. 346. 



More slender than >S'. fallax and much more iridescent ; head 

 black, antennae, labrum, palpi, and legs fiavescent ; prothorax 

 chestnut-brown, with the discoidal part darker and very iridescent, 

 basal depressions hardly punctulate ; elytra elongate, subparallel, 

 striate, with two punctures on the third interval, the first one at 

 about the median part, the other at the top of the declivity ; the 

 colour is light chestnut -brown, iridescent with a dorsal black band 

 extending on from the base to a short distance from the apex, 

 reaching the third stria, but extending in the median part as far
