420 Mr. G. Lewis on new 



gidium with an irregular transverse band of punctures at the 

 base ; the pygidium smooth ; the prosternuni — keel a little 

 narrowed before the coxae, without striaj ; the mesosternum 

 with a lateral stria only, whicli is incurved at the anterior 

 angle. 



This species is a little broader and flatter than Platijsoma 

 Coiifuciif Hilars. ; the pygidium .smooth, and the mesosternal 

 stria does not continue anteriorly. The striation of the head, 

 thorax, and elytra is, however, almost identical in both species.

 smooth and deeply impressed, dividing the disk into two 

 small bosses in the punctulate surfaces ; the thorax sparsely

 within is a feebly sinuous detached carina, which is a little 

 shortened anteriorly and more abbreviated behind ; tlie elytra 

 — strijfi 1-4 complete, 5 and sutural also complete and joined at 

 the base ; the propygidium has oblong punctures, not closely 

 set, with fine punctures between them ; the pygidium has a 

 similar sculpture, but the punctures are dense and give an 

 appearance of opacity, there is a feeble median carina before 

 the apex to be seen only in certain lights ; the prosternum — 

 keel very finely carinate at the sides and base, narrow ante- 

 riorly, triangularly widening out at the base ; the meso- 

 sternum smooth, feebly sinuous in front, with a very fine 

 marginal stria; the tibiai — anterior 7-8 -spinous, dilated and
