Although at lirst siglit very much like many other species 

 of the genus, a close examination shows this to have many 

 peculiarities which make it in reality a very isolated form. 

 The clypeus is smooth and shining, cut off by a deep furrow- 

 behind, and of rather unusual shape, being sliort and broadly

 tinctly margined all round and the elytral punctures are verv 

 strong, pigmented and irregular, the usual longitudinal rowd 

 being broken up, except that adjoining the suture.

 kindly sent to me from C^openhagen by Dr. Adam Boving,
