tate on their outer margin. The underside and legs are much 

 clothed with rather long ferruginous hairs. 



In the male the pygidium is glabrous, shining, and impunc 

 tate, except about the sides and base, while the apical Yentral 

 segment is widely and roundly emarginate at its apex ; in the 

 female the former is closely rugose over its whole surface, and 

 is clothed with reddish pubescence, while the latter is evenly 

 rounded off behind. 



The absence of elytral costae seems in itself sufficient to 

 distinguish this from all the other described species attributed 

 to the genus except S. convexiusculus, Macl. in which, however, 

 the elytra are said to be " strongly striato-punctate." 



The maxillse have the intermediate tooth deeply bifid, and the 

 basal one feebly trifid. 



I have received two examples (taken in Sedan) from Mr. 

 Bothe ; there are also two in the South Australian Museum. 

 >S'. angustatus, sp. nov. Sat convexus ; nitidus ; obscure brunneus ; 

 capite, prothorace, pedibus, et abdomine postice (nonnuUis 

 exemplis) plus minusve piceis vel nigris, capite transversim 

 rugato, tuberculo conico armato, prothorace canaliculato 

 punctulato ; elytris vix costatis sparsim punctulatis. Long. 

 8i 1. ; lat. 4 1. 



The protuberance on the head is no more than a smooth 

 conical tubercle ; in other respects the head resembles that of 

 the preceding, being rather evenly narrowed from just in front 

 of the eyes to the apex, where it is truncated wdth a perpen- 

 dicularly thickened front and somewhat elevated margin. The 

 pro thorax is scarcely more than half again as wide as down the 

 middle it is long, and its base is about half again as wide as 

 the front margin ; its sides are rounded, its surface rather 

 sparingly and very finely punctured, the puncturation, how- 

 ever, becoming large and coarse in the longitudinal channel, 

 which is wide behind, punctureless, and almost interrupted at 

 the middle, and in the front becomes in the male a large round 

 concavity, in the female a vague wide depression (this is very 

 likely not to be a reliable sexual character) ; the front part of 

 the prothorax is not conspicuously declivous (as it is in the 

 preceding species) ; the front angles are sharp, the hinder 

 obtuse, and preceded by a short, gentle sinuosity of the lateral 

 margin. The scutellum is sparingly and coarsely punctured. 

 The sculpture of the elytra consists of a strong, scarcely punc- 

 tured sutural stria, followed by a smooth space, on which are 

 a few punctures near the base, then a row of fine punctures reach- 

 ing two-thirds down the elytron, then a smooth scarcely convex 

 space (slightly punctured near the base in one example), then 

 a row of punctures similar to the first row (or a little shorter),
