231. Platyrhopalus mandersi, sp. n. 



Elongate, oblong, shining, pitchy black, practically unicolorous, 

 with fine setse at the sides ; there are traces of small reddish 

 yellow spots behind the middle, and the 

 suture is sometimes very narrowly reddish; 

 head short and broad, with the eyes large 

 and prominent occupying the whole of its 

 sides ; antennae with the first joint large 

 and quadrangular, produced into a blunt 

 tooth just above the insertion of the club, 

 which is oblong, twice as long as broad, 

 slightly narrowed towards the apex which 

 is rounded, truncate and strongly im- 

 pressed longitudinally at the base, with 



the exterior angle slightly notched, forming

mandersi. two very snort broad blunt teeth, margins 



all carinate, underside distinctly convex 

 and raised in the middle into a broad point, if viewed from the 

 side ; pronotum cordiform, about as long as broad, with the sides 

 strongly rounded in front, then contracted abruptly and gradually 

 widened to the base ; elytra very long, parallel-sided, very shining, 

 extremely finely and scarcely visibly punctured ; pygidium dull, 

 very finely sculptured ; legs stout, tibia) with the apical angles 

 sharply produced, femora grooved to receive tibia?, tarsi rather long, 

 onychium nearly as long as the other joints together ; trochanters 

 of posterior tibiae large ; underside of abdomen smooth ; the fine 

 lateral setae are thickest at and just behind the shoulders. 

 Length 9 millim.

This fine and distinct species forms a separate section of the 

 genus with P. comotti, Gestro, being distinguished from all the 

 other species by its elongate, oblong club. From P. comotti it may 

 be easily separated by its considerably larger size and by the 

 absence of the transverse, irregularly dentate patch towards 

 the apex of each elytron, which is characteristic of the last-named 

 species ; the exterior angle of the club, moreover, is more acutely 

 dentate in P. comotti, and the elytra are proportionally shorter and 

 broader with the shoulders more markedly produced. 



It is possible that these two species may have generic value.
