264 Mr. Frederick Bates on 



Thorax very convex and smooth, broadly emarginate in 

 front, scarcely sinuous at the base, strongly rounded at the 

 sides, sviddenly contracted behind near the base ; lateral 

 margins faintly sinuous, hind angles rather prominent 

 and pointed. Scutellum convex, transverse. Elytra oval, 

 wider than the thorax at the base ; punctate-striate, the 

 punctures large and rounded ; the intervals subconvex 

 at the sides and on the middle, flat towards the suture ; 

 shoulders depressed, with the humeral angles prominent. 

 Prosternal process rounded behind, the intercoxal broadly 

 rounded in front. Legs rather long ; fore and interme- 

 diate tibiae rather strongly arched, the hind faintly so. 

 Body beneath, and legs, shining black ; antennee and 

 palpi piceous. 



The more than ordinarily roundecl and convex thorax, 

 and the oval form of the elytra, give to the present species 

 a facies different from any of the preceding.

Characters of Hypaulcvx, but differs in having the head 

 more exserted and narrowed behind ; the eyes more dis- 

 tant from the prothorax ; the antenna), relatively, more 

 slender^ with joints 3-6 subequal, 8-11 narrower, longer 

 and less depressed ; the thorax bisinuate in front, with 

 the angles prominent, the lateral margins more decidedly 

 crenulate, the base distant from the elytra, with its 

 angles free ; the thighs more attenuate at the base ; the 

 fore tibige elongate and strongly curved ; the sculpture 

 of the elytra alveolate, etc, ; characters which, taken 

 altogether, give to the genus a different facies to that of 

 the preceding.
