Palpi with the terminal joint slender, acute at the apex ; maxillary longer than

 what transverse, the lateral margins spinose : elytra more or less convex, the 

 apex frequently spinose : the disc more or less variegated : body short : legs 

 moderate : femora clavate : intermediate tibiae unidentate without.

 they dijOfer from the preceding and following by the union of their 

 convex body with the subfiliform, acute palpi, elongate pilose an-

 unidentate tibia?, &c. : — they frequent dry wood, especially what 

 are termed " dead hedges," in June and July.
