Platysoma Jatimarginatum, sp. n. 



Oblongum, subparallelum, depressum, rufo-brunneum ; fronte leviter 

 impressa, minutissime pmictulata, stria integra ; pronoto, stria 

 marginali integra, laterali a margine valde distante aiitice abbre- 

 viata ; elytris striis 1-3 integris, 4-6 apicalibus ; prosterno bi- 

 striato, angustato ; tibiis anticis S-dentatis. 



L. 3 mill. 



Oblong, rather parallel, depressed, reddish brown ; the 

 head, surface with an extremely fine punctuation, not dense, stria 

 complete and fine and widely straight anteriorly ; the thorax, 

 marginal stria somewhat cariuate and passes the posterior 

 angle, behind the head it leaves the edge and is obscurely 

 crenulate, tliere is an inner lateral stria some distance from the 

 margin which leaves a very wide interstice, the stria touches 

 the base but is shortened anteriorly at a point in a line with 

 the back of the head, this stria is broad and bends inwards in 

 the middle; the elytra, striae, external liumeral complete, 

 inner humeral wanting, 1-3 rather fine and complete, 4-5 

 apical and almost reaching the middle, sutural longer than 

 the last two and just passing beyond the middle ; there are 

 microscopic punctures on the thorax and elytra ; the pro- 

 pygidiura has a few large, shallow, and irregular punctures 

 with minute points intermixed ; the pygidium is very similar, 

 but the large irregular punctures are transversely disposed 

 near the base ; the prosternum, keel narrow, surface with a 

 few minute punctures, bistriate, striae looped together at the 

 base, outside the striae the prosternum is minutely strigose, 

 lobe rather wide and distinctly punctured, base semicircular 

 in outline ; the mesosternum emarginate, with a short stria on 

 each side at the angles, within these short stri» there is the 

 usual mesosternal marginal stria, which follows the course 

 of the emargination, and then, leaving the edge, passes some- 

 what obliquely along the side of the metasternum ; the ante- 

 rior tibiai are 3-dentate.

Platysoma bipunctatiayi, sp. n. 



Oblongum, subparallelum, depressum, rufo-brunneum ; protioto stria 

 laterali integra, utrinque nigro bipunctato ; elytris striis 1-3 

 integris, 4-5 apicalibus, dimidiatis, suturali nulla ; prosterno bi- 

 striato ; tibiis anticis 5-dentatis.
