apically, and almost evanescent in the middle, second more 

 distinct and complete, third widely interrupted in the middle; 

 the propygidium is transversely punctate ; the pygidium is 

 laterally depressed, convex in the middle, punctures clear and 

 well-detined within the depressions, fine and less close on the 

 convex area ; the prosternum is smooth and bistriate, strite 

 feebly sinuous and not quite reaching the base ; the meso- 

 sternura is widely emarginate and has no anterior stria ; the 

 anterior tibiae 5-dentate. 



The species in size and outline resembles a small specimen 

 of Platysoma ovatum, Er., but the tlioracic stria and the form 

 of the sterna are similar to Apohletes fossistoma, Mars.

Platysoma pinnigerum^ sp. n. 



Eloagatum, subparallelam, convexum, nigrum, nitidum ; fronte 

 impressa, stria Integra, pronoto disco bipunctato, stria marginal! 

 lateralibus valida, antice integra, basi in medio vix iuterrupta ; 

 elytris striis 1-3 integris, 4-5 dimidiatis ; propygidio pygidioque 

 planis, puuctatis ; prosterno angustato baud striate ; mesosterno 

 emarginate, stria marginal! integra ; tibiis late dilatatis.

Elongate, somewhat parallel, convex, black and sliining ; 

 the head smooth, stria well-marked over the eyes, complete 

 anteriorly, but fine and irregular, sinuous in the middle, im- 

 pressed anteriorly ; the thorax, marginal stria strong at the 

 sides, fine but complete behind the head, and at the base it is 

 continued until it is narrowly interrupted before the scutel- 

 lum, on the disk are two small but very distinct punctures, 

 which with the antescutellar point form a triangular arrange- 

 ment, thus — •.' ; the elytra, tlie epipleural striai are carini- 

 form and complete, humeral short, fine, and oblique, strige 1-3 

 strong and complete, 4 apical and dimidiate, 5 similar but a 

 little shorter ; the propygidium and pygidium are flat and 

 rather densely punctate ; the prosternum impunctate, keel 

 narrow except at the base; the mesosternuin emarginate 

 anteriorly, marginal stria complete and well defined; the 

 iibise are all greatly dilated, anterior pair -l-dentate, inter- 

 mediate and posterior 4-spinose. 



Platysoma palmipes, Lew., and P. extrarium, Lew., are 

 somewhat similar to the species above, but they are less elon- 

 gate. In P. pahnipes the tarsi are short, but in P. extrarium 

 and P. pinnigeriim they are of normal length and not very 

 dissimilar to those of P. ovatiim, Er.
