Platysonia uniformed sp. n. 



Ovatum, subconvexum, niger, nitidum ; fronte impressa stria trans- 

 versa recta ; elytris striis 1^-2* integris, 3* in medio late inter- 

 rupta, 4* apicali, 5* dimidiata ; prosterno baud striate. 



L. ^ mill. 



Oval, somewhat convex, blacky shining; the head micro- 

 scopicallj punctulate, impressed anteriorly with a transverse 

 stria, well-marked and straight ; the thorax arched at the 

 sides, marginal stria complete, fine behind the neck, strong 

 at the sides, and bent inwards at the base, interstice narrow, 

 ante-scutellar fovea very minute; the elytra, stria3, subhumeral 

 wanting, 1-2 complete, 3 short and basal with an apical 

 appendage of the same length, 4 apical and similar to the 

 appendage of the third, 6 apical but reaching the middle, with 

 a wide interspace between it and the suture ; the propygidiura 

 with a band of rather large punctures, posterior margin 

 smooth ; the pygidium impressed slightly laterally, with 

 smaller punctures evenly set over the entire surface ; the 

 prosternum without striee, constricted before the coxaj, ante- 

 rior lobe finely and sparsely punctulate, anterior border 

 marginate ; the mesosternum somewhat deeply emarginate, 

 marginal stria fine, entire, and at the emargination close to 

 the edge. 



Somewhat like Platysoma mirandum, Mars., in sculpture, 

 but more oval and more convex.

L. 4 mill. 



Oblong, parallel, somewhat convex, black, shining; the 

 head very minutely punctulate, frontal transverse stria 

 straight ; the thorax broadly margined with rather large 

 punctures, lateral stria terminating behind the eye, and behind 

 either eye is a short bent stria detached from the margin ; the 

 elytra, strige 1-3 complete, 4 very short and apical, o apical, 

 very short, almost a linear puncture, sutural usually as long 

 as the fifth, but further from the apex ; the propygidium with 

 a few large punctures, closest generally near the outer 

 margin ; the pygidium with similar punctures, but smooth at 

 the apex ; the prosternum is without stria, and the meso-
