Stenophida.

Oxyopisthen, Thorns., was intended to supersede Sclioulierr's 

 Megaproctus, the name being preoccupied ; but Lacordaire, con- 

 sidering the African species generically distinct from the Indian, 

 adopted the name in bis great work (Greu. des Coleopt. viii. 282), 

 witb characters confining it to the former. In Oxyopisthen tbe 

 large penultimate joint has a short cleft for tbe insertion of the 

 claw-joint ; the claws short and united ; and the pygidium sub- 

 horizontal and pointed at the apex. The species here described 

 has the narrow contour of a Periphemus.

 stitiis latis planatis, uniseriatim punctatis. Long. 3 lin.

 long as the elytra, finely and closely punctured; scutellum elon- 

 gate ; elytra narrowly striate-punctate, punctures inconspicuous, 

 interstices broad and flat, each with a row of close-set round 

 punctures ; pygidium punctured at the base, beyond studded 

 with white scales ; body beneath finely punctured ; tibiae salcated, 

 strongly mucronate.
