The broad prothorax with rounded sides, and the wide and not 

 very convex elytra are the conspicuous features of this species. 

 The strise of the elytra are deep and strongly punctate (more 

 especially so in the male) on the anterior part of the elytra ; 

 towards the apex, and on the sides the strise are shallower and the 

 punctures fine. On the posterior part the elytra are flushed with 

 jDurpl", particularly towards the sides. Its affinity is to iS, civilis 

 from which it differs, inter alia, in its thorax being wider behind, 

 and in its elytra having deeper and more strongly punctate striae.

This species may be distinguished from .S'. obesula, which is 

 nearly allied to it, by the absence of any bluish tint on the elytra, 

 and by its more elongate shape ; by the striae of the elytra being 

 shallower and much more finely punctate; and by the shape of the 

 prothorax, which is not so transverse, and is narrower behind than 

 in front ; the lateral margins of the elytra are narrower and more 

 sinuate behind. From S. habitans, another allied species, which a 

 description might not differentiate much, though they are quite 

 distinct, it differs, inter alia, in its prothorax being narrowed
