 fronte carina transversa instructa, cljpeo apice bidentato ; thorace 

 transverse, convexo, fere laevi, lateribus leviter arcualis, laevissime 

 bisinuatis ; elytris tborace perparum angustioribus, quam latitu- 

 dine paullo brevioribus, tenuiter striatis, striis Icevibus, interstitiis 

 fere planis, loevibus ; pygidio laevi ; tibiis anticis obtuse triden-

 notato, a metastemo linea fortiter angulata diviso ; femoribus

This species is closely allied to U. Batesi, Harold, hut is 

 Btil] shorter. The clypeus has the teeth shorter and more 

 triangular. Tlie thorax has the sides less abruptly turned 

 inwards at the anterior angles; the lateral impression is elon- 

 gate, but does not run off into a line at each end. The elytra 

 have the striae tiner and apparently impunctate. The line 

 dividing the mesosternum from the metasternum is strongly 

 angular, having an angle of about 110°, leaving the meso- 

 sternum very long ; whereas in U. Batesi the line is bent at 

 an angle of about 80°, reaches forward almost to the front 

 of the mesosternum, and has the apex itself rounded.
