This species, which I received from M. Salle as the Attel. variabilis , 
Sch., must be separated from that Proteus-like intertropical species. 
The punctures of the rostrum are shallower. The head hears pos¬ 
teriorly an evident canalicula reaching to and between the frontal ridges, 
whilst in Attel. variabilis a slight short suhfoveiform occipital impression 
is only perceptable. The thorax is much less convex, transversely 
as well as lengthwise, indeed almost flat; the sides are conically, very 
slightly roundly ampliate towards the base ; the impression on each side 
of the disk is not a fovea, but a real oblique impression. The scutellum 
is less convex posteriorly, perhaps also less acute at the middle of 
its truncature. The elytra are more flatly descending to the apex ; their 
striae are thinner, with their punctures smaller, much more approximate, 
consequently much more numerous. The legs are more slender, 
especially the anterior femora, and the denticulations of these are much 
smaller.
