divergence behind the middle; posterior angles right angles; base 
nearly straight. Disk convex, punctured, with a slightly im¬ 
pressed dorsal line and a shallow round impression on each side 
(this character would probably be wanting in some specimens, as in 
8. Mitchellii , Hope); puncturation of the sides rather deeper than 
that of the disk. Elytra punctate-striate, not quite twice as long 
as broad; sides sinuate above the middle; apex rounded. Beneath 
punctured, centre of thorax and breast thickly, legs and abdomen 
sparsely covered with greyish hairs. Length Ilf lines; breadth 
5 lines.

Head punctured, impressed between the eyes, covered with 
short grey hairs. Thorax at the base once and three-quarters as 
broad as long. Anterior margin slightly raised, produced in 
its centre and at its angles; sides diverging for about half their 
length, then subparallel to the base; posterior angles nearly right 
angles. Base with a wide median lobe. Surface deeply punctured ; 
disk with an impressed dorsal line. Elytra finely punctured, 
striate, the sixth interstice vermiculate; sides subparallel till past 
the middle, then converging to the apex, which is truncate and
