times as broad as long; sides straight and nearly parallel, the 

 anterior angles obliquely truncate, the hinder ones produced, 

 subacute ; disk smooth and shining, moderately excafvated 

 transversely across the disk, the excavation not reaching to 

 the lateral margin. Scutellum trigonate, shining black. 

 Elytra oblong, broadly rounded at the apex, deeply and 

 closely punctured, the interspaces irregularly elevate-reti-

Front impressed ; joints above the encarpse with a narrow 

 longitudinal groove ; encarpge semilunate, contiguous ; clypeus 

 large, transverse-quadrate, rugose, faintly carinate on the 

 median line, clothed with short adpressed hairs ; third joint 

 of antennas twice the length of the second, scarcely more than 

 half as long as the fourth ; the lower two thirds of the basal 

 joint obscure fulvous, its upper third, together with the re- 

 maining joints as far as the tenth, black*. Thorax three 

 times as broad as long ; sides obliquely converging from base 

 to apex, moi'e quickly converging and slightly rounded just 

 behind the latter ; the anterior angles armed with a very short 

 excurved tooth ; the hinder ones slightly produced, acute ; 

 disk transversely concave, rugose-punctate. Elytra subqua- 

 drate, oblong, broadly rounded at the apex, convex, strongly 

 and closely punctured, the interspaces irregularly wrinkled ; 

 olivaceous with a metallic tint, each elytron with a broad 

 biflexuose band before the middle, and a small spot close to 

 the apex near the suture, obscure fulvous. Segments of ab- 

 doipen each marked on either side with a large nigro-ajneous 

 patch ; apex of pygidium also nigro-ajneous. 



Prasyptera approximata.
