An Adoretus which appears to be rather common at St. 

 Helena. It may be known amongst the few Lamellicorns 

 here enumerated by its narrowish, oblong outline, less convex 

 body (which is sparingly clothed with a short, decumbent, 

 cinereous pile) and more T/eUowtsk-brovm hue, by its rather 

 large head, greatly developed eyes, and semicircular clypeus, 

 by its extremely abbreviated prothorax and subcostate, rugu- 

 lose elytra, and by its unequal claws. The examples from 

 which I have drawn out the above diagnosis were captured 

 by Mr. Melliss.
