 elytris striis subcrenulatis, 1-3 integris, 4 basi vix abbreviata

H. impiger is shorter and much more convex than //. navus. 

 Mars., and niponicus, Lew. It is most similar to the last, 

 but differs from it in having the thorax less wide, and the 

 lateral stria is incurved at the base and there is a shallow ante- 

 scutellar fovea near but not on the edge; the elytral fifth and 

 sixth stride are longer and the punctuation of the pygidia is 

 closer and rather finer. The prosternal striae are short and 

 iiitercoxal, like those of navus ; in niponicus they extend 

 along the sides nearly to the end of the keel.

 reference : — 



" Platysoma puUum, Gerstacker. 



" Oblongum, cylindricum, nigrum, nitidum, asaeo-micans ; pro- 

 thorace estriato, subtiliter punctulato ; elytrorum stria suturali 

 utrinque, secunda pone basin abbreviata, sequentibus subiutegris.

"E minimis hucusque cognitis speciebus. Caput con- 

 fertim subtiliter punctulatum, fronte utrinque sulcata, sulcis 

 clypeum versus convergentibus. Prothorax transversus, 

 lateribus parallelus, angulis anticis late rotiindatis, posticis 

 rectis, basi in medio angulata, supra ubique puuctis sub-

 dimidio longiora, parallela, apicem versus crebre punctata : 

 singula 6-striata, striis evidenter punctatis, suturali basi 

 apiceque, 2" baud procul pone basin, 6^ antrorsum dimidiatiiu
