Head as long as broad, contracted in front, the apex 
blunt and reflexed ; there is a transverse slightly-raised 
ridge between the antennz, and a perpendicular lamina 
between the eyes; this lamina is emarginate almost to 
its base; the clypeus is somewhat sparingly and finely 
punctured, the forehead rather more thickly and distinctly 
punctured. The thorax is evenly, moderately thickly, but 
not very strongly punctured. The elytra are as wide as 
the thorax and the same length, narrowed towards the 
apex, which is rounded; the scutellar region is somewhat 
flattened ; the striz are very delicate and very finely and 
sparingly crenate-striate; the interstices flat, that next 
the suture almost impunctate, the next sparingly and very 
delicately punctured, the rest becoming more distinctly 
punctured as they approach the sides. 
Hab.—iushiu and Nipon; in woods and shady places 
under trees.
