 sively close to it. 



aS'. rubrocincta, Kerremans. This name having been previously 

 employed by M. Gehin (Bull. Soc. Mosel., 1855, p. 13) for a dif- 

 ferent species of Stigmodera, I propose to substitute cincta for 

 M. Kerremans' name.

The elytra at their posthumeral dilatation are of the same 

 width as at their post-median dilatation, and very slightly wider 

 than the greatest Avidth of the prothorax. The post-median com- 

 mon spot and the two other post-median spots form a transverse 

 series across the elytra. The base of the prothorax is exactly the 

 same width as the base of the elytra. 



This species is distinguished from all its congeners except a 

 small group by the following in combination : — Underside (except 

 sides of prosternum) of uniform dark colour, prothorax and elytra 

 with markings, elytra spinose at apex ; of the few species not 

 greatly difterent in size presenting this combination it seems 

 nearest to S. gibbicollis, Saund., and fascigeixt, Kerremans ; from
