its prothorax is a little narrower (or less transverse), more coni 

 less rounded (and more narrowly margined) at the sides, and less 

 constricted along its extreme base though, at the same time, more 

 deeply, and definitely, impressed transversely in the centre.

An interesting little Atomaria which was discovered in Gornera, 

 during the summer of 1864, by the Messrs. Crotch. There can be 

 no doubt that it is a truly indigenous species, partaking in some 

 measure of the general character and structure which obtain in the 

 A. insecta and alternans of the Madeiran Group. Although by no 

 means minute, it is the smallest of the Atomarice hitherto detected 

 at the Canaries ; and it is remarkable for its very shining surface, 

 comparatively rounded bulbose form, and its usually dark hue. The 

 colour however is (as in most of the members of this genus) extremely 

 inconstant ; for although when mature the insect is generally almost 

 entirely black, it is nevertheless sometimes a little diluted (or rufcs- 

 cent) in various parts (particularly towards the base, and along the 

 suture, of its elytra), and immature examples of it are often wholly 

 ferruginous.
