The " trilobed outline " of the front of the head is exceptionally 

 well defined, the middle lobe appearing to be slightly longer than, 

 and about a quarter of the width of, the lateral lobes. The clypeus 

 is well rellexed at the sides, arcuately and somewhat strongly 

 emarginate in front, and margined all across, its sides convergent 

 hindward at their extreme base, its sculpture a little closer but not 

 coarser than that of the rest of the head with which it does not 

 form a continuous surface, the suture being well marked, angulated 

 in the middle and sinuous on either side. Theprothorax is nearly 

 f again as wide as long, its base about half again as wide as its 

 front margin which is strongly emarginate, with sharp well pro- 

 duced angles (from some points of view it has a bisinuate appear- 

 ance) ; its sides are slightly arched being almost at their widest at 

 the base ; its hind angles are seen to be much rounded off when 

 the true margin is examined, but from some points of view they 

 appear sharp and slightly produced hindward ; the punctures of 

 the surface are rather coarse and spaced so that about 16 of 

 average distance would lie longitudinally down the middle line ; 

 the base is distinctly bisinuate. the middle lobe moderate. The 

 transverse wrinkling of the elytra is moderately conspicuous from 

 some points of view, their lateral fringe normal, their apical mem- 

 brane narrow but distinct. The hind coxae are scarcely shorter 

 than the metasternum, both being rather deeply punctured, some- 

 what finely and closely at the sides but more coarsely and spar- 

 ingly towards the middle, the former having a well defined Isevigate 

 antero-internal space near which its puncturation is very coarse 

 indeed. The puncturation of the ventral segments resembles that 

 of the metasternum but does not become so coarse in the middle. 

 The ventral series consist of stout short bristles. The hind femora 

 are moderately wider than the intermediate, their surface being 

 much punctured and their inner apical angle but little defined. 

 The lower two teeth on the front tibias are long and robust but 

 not very sharp, the uppermost well defined but less than half as 

 large as the 2nd. The 2nd joint of the hind tarsi is exceptionally 

 long as compared with the basal one ; the hind claws are robust,
