 thickened, second very short, moniliform, third and fourth equal, 

 each twice the lengtli of the second, four following joints equal, 

 each rather longer than the fourth, slightly compressed (the 

 rest wanting) ; mandibles and eyes black, the latter elongate, their 

 inner edge deeply notched. Thorax not quite twice as broad as 

 long ; sides rounded and converging from base to apex, hinder 

 angles acute, slightly incurved, produced slightly backwards ; 

 basal margin obsoletely bisinuate on either side, medial lobe 

 scarcely produced, its apex broadly truncate ; upper surface 

 convex, subcylindrical in front, smooth, impunctate. Scutellum 

 trigonate, its apex truncate. Elytra moderately lobed at the 

 base, not thickened in the neighbourhood of the scutellum ; each 

 elytron with eleven regular rows of punctures, the punctures 

 deeply impressed in front, smaller and less distinct towards the 

 apex, pale piceous ; interspaces plane, obsoletely convex on the 

 outer disc ; the extreme basal border, together with the basal 

 margin of the scutellum, and four spots on each elytron, black ; 

 these spots, which are subrotundate, are placed as follows, viz., 

 two just below the basal margin, one on the humeral callus, the 

 other half-way between the callus and the suture, and two just 

 below the middle of the elytron, the outer one, larger than the 

 others, in the middle of the outer disc, the other small, in the 

 centre of the inner disc. Pygidium somewhat closely punctured, its 

 hinder border semicircular. Body beneath sparingly clothed with 

 very short seneo-sericeous hairs. Anal segment of abdomen 

 impressed with a large, deep, transversely ovate fovea,
