new Species of Histcrldse. 239 



closely but not coarsely punctured, tlie latter is slightly con- 

 vex ; the prosternum, keel is broad and flat and truncate at 

 both end'^, the hxteral striaa are very tine and feebly sinuous 

 before tlie coxte, within the strict and parallel to them is a 

 very shallow channel, more conspicuous than the striae and 

 shortened a little at the base; the niesosternum is transverse 

 and narrow, but relatively as bi'oad as in Macros iernus 

 lofcrtei, anteriorly it is almost straight, not sinuous, across 

 the middle there is a bowed striaj somewhat fine, and it does 

 not reach the outer edges; the anterior tibiae are 10-11- 

 denticulate and all the tarsi are distinctly hirsute.

PlatyVister procerus. Lew. 



I have specimens of this species which measure 11^ mm., 

 as stated in the preamble ; the raesosternal marginal stria is 

 traceable in the type behind the emargination, but it is not 

 so seen in other examples. The localities of the species are 

 Kumaon, Sikkim, and Yunnan, and it has been found in the 

 burrows of a loiigicorn in willows. 



Plattjsoma viiim'cum, sp. n. 



Oblougo-ovatum, convexiusculum, nigrum, nitidum ; fronte stria 

 late arcuata ; pronoto stria integra, margine laterali parallela ; 

 elytris striis 1-6 integris, 4 parum abbreviata, o et suturali 

 dimidiatis ; pygidio transverso puuctato apice lievi ; prosteriio 

 angustato ; mesosterno emarginato, stria integra. 



L. 2| mm. 



Oblong-oval, little convex, black, and shining ; the head 

 microscopically punctulate, stria comj)lete, widely bowed 

 from side to side ; the thorax, lateral stria complete and 

 rather close to the margin, strongest behind the head, with u 

 small antescutellar |)uncture ; the elytra, striae 1—3 complete, 

 4 little shortened at the base, with a basal puncture, 5 and 

 sufural dimidiate ; the propygidium is rather coarsely and 

 somewhat unevenly punctate, v.ith a narrow posterior margin 

 smooth ; the pygidium has similar punctures transversely 

 placed close to the base, leaving the apex widely smooth ; the 

 mesosterimm strongly nnuf^inale, stria following the contour 

 of the emargination and continuing laterally to the base of 

 the metasternum, suiface of the sterna microscopically [>uuc- 

 tulate ; the anteiior tibiaj are 5-denticulate. 



The sculpture of the pygidia and the form of the thoracic 

 stria resemble I\ j>jfjidinle, Lew., but this species has an 

 oval outline.
