Variat partibus obscurioribus lsete castaneis aut rufescentibus, re- 
liquis laete rufis aut flavescentibus. 
About the size of Attel. Troglodytes , but much narrower pro¬ 
portionally ; the elytra are more evidently longer than wide,less convex; 
the thorax is more coniciform, evidently punctate on the centre as well 
as on the sides of the disk; the sides beneath, the pectus and the 
pygidiura are not so strongly punctate ; the head and thorax are much 
thicker. 
Varies very much in coloration ; some of the darkest specimens have 
only the suture and margin of the elytra rufous; in the lightest speci¬ 
mens the scutellum is always darker than the elytra, and these have still 
a blackish basal marking inside the shoulder.
