Antennae about half the length of the body ; vertex smooth, impunctate. 

 Thorax distinctly broader than long ; sides obliquely diverging from the base to 

 beyond the middle, where they form a distinct angle, thence obliquely converging 

 towards the apex, outer margin finely but irregularly serrulate ; upper surface 

 coarsely punctured, transversely sulcate just before the base, middle disc with a 

 smooth elevated vitta, which extends from the anterior edge of the basal sulcation 

 to the apical margin, its upper surface longitudinally grooved ; on either side, about 

 half way between the vitta and the outer margin, is a large strongly raised callosity. 

 Elytra sub-elongate, parallel, obtusely rounded conjointly at the apex, the outer 

 margin serrulate ; each elytron with eight regular rows of punctures, arranged in 

 pairs ; the second, fourth, and sixth interspaces from the suture oostate, the outer 

 costa less strongly elevated than the others ; spaces between the pairs of punctures 

 transversely costate.

 beneath with short, flocculent, white matter, all segments visible, the margin all 

 round with a close fringe of short, delicate hairs. Head obtuse, prominent ; 

 antennae (Fig. 1 ; Fig. 2, terminal joints more enlarged) black, rather short, slightly 

 tapering, 11-jointed, with projecting simple hairs, some of them very long; 1st 

 joint very wide and short ; 2nd and 3rd cylindrical, longest, 2nd longer than 3rd ; 

 4th to 10th shorter, in length subequal, broad short-clavate, being smaller at the 

 base than at the rounded apex, which, transversely, is narrowly yellowish ; 11th 

 longer, obtuse-fusiform, with two of the apical hairs very long. Eyes black, simple. 

 Thorax transverse, middle depressed, sides prominent ; posteriorly an elevated, 

 somewhat angulated, scutellatc area extends for a considerable spaco on to the base
