third and fourth equal, each twice the length of the second. 

 Thorax rather broader than long ; sides parallel, obliquely 

 converging at the apex, obsoletely angled before the middle ; 

 anterior angle produced, obtuse; middle portion of basal 

 margin sinuate-emarginate ; disk coarsely rugose-punctate, 

 rather more sparingly punctured on the middle disk ; in 

 front, behind the apex, is a very shallow, ill-defined, trans- 

 verse sulcation, which terminates on either side some distance 

 within the lateral margin ; just in front of the basal margin 

 is a faint longitudinal depression. Scutellum longer than 

 broad, its apex obtuse. Elytra subelongate, parallel, con- 

 vex, coarsely rugose-punctate, the puncturing finer towards 

 the a])ex ; each elytron on its middle third near the lateral 

 margin with a raised cosla, the space on either side longitu- 

 dinally excavated j the suture from its middle nearly to the 

 apex is thickened and forms a longitudinal costa ; before its 

 apex this costa becomes subsutural, and leaves a very narrow 

 space between itself and the sutural margin.

Hah. Caffraria. 



Head obliquely deflexed ; lower face produced below the eyes; 

 vertex shining, impunctate ; encarpte transverse, contiguous ; 

 carina not well defined, narrowly wedge-shaped, its surface im- 

 pressed "with a shallow fovea ; antennse rather more than half 

 the length of tlie body, filiform, slightly thickened towards 

 the apex, the second joint short, ovate, the third and fourth 

 equal, each more than half as long again as the second. 

 Thorax nearly twice as broad as long ; sides rounded, the 

 hinder angle nearly obsolete, the anterior one mucronate ; 

 disk finely but distinctly punctured, impressed just in front of 

 the middle with an ill-defined, yqxj shallow, subarcuate exca- 

 vation, divided into two portions by a slightly and indis- 

 tinctly raised vitta, the surface immediately in front obsoletely 

 thickened. Scutellum trigonate, pitchy black. Elytra nar- 

 rowly oblong, parallel, convex, rather strongly punctured, 

 the interspaces granulose ; each elytron with a narrow sutural
