one is the smallest, along the apical edges of the elytra is a 

 broad band of an intricate sculpture somewhat similar to that 

 of the mesosternura, this gives way to simple points on the 

 dorsal area, a fine marginal stria, which apparently arises in 

 the dorsal pit, continues close to the edge round the apical 

 margin ; tlie propygidium has tw^o smooth tubercles on its 

 basal edge and the surface otherwise is densely and clearly 

 ocellately punctate ; the pygidium, the lower half is bi- 

 impressed, apex has a small concave smooth space surrounded 

 by conspicuous irregular ridges which occupy the impressed 

 area, the upper half has an irregular sculpture somewhat 

 resembling that of the mesosternum ; the prosternum, anterior 

 lobe with an elevated margin, keel feebly concave with 

 lateral cariniform stride, which indistinctly meet in front and 

 are slightly sinuous near the coxaa ; the mesosternum, anterior 

 edge strongly bisinuous, with a line of punctures across the 

 projecting centre, marginal stria fine and clear, but it does 

 not follow the sinuosities, surface-sculpture (with that of the 

 metasternum, between which there is no visible suture) con- 

 sists of small crescent-shaped stri« with a puncture within 

 each, these half-circles bend towards the head and as they 

 are fairly closely set give an imbricate appearance to the 

 surface. The mesosternum and metasternum are bistriate 

 laterally. There are eight well-developed spines on the 

 anterior tibise and other smaller ones, the larger are divided 

 in the middle by a rather wide interval.

Oblong - oval, convex above, pitchy-brown, somewhat 

 shining, densely punctulate ; the hf ad, frontal stria fine and 

 widely sinuous anteriorly, strong before the eyes and semi- 

 circular in outline, median anterior area and base of the 

 epistoma depressed ; the thorax punctulate like the head, 

 with an ante-scutellar fovea, the lateral rim is finely raised 

 and carried on behind the head as a stria, within a very 

 narrow and convex interstice is a stria which reaches from 

 the base to a point behind the anterior angle, inside this stria 

 there is a broad somewhat irregular depression, narrowest at
