Platyporopterus, n.g. 



Head convex, almost concealed by prothorax ; ocular fovea 

 distinct. Eyes widel}' separated, moderately faceted. h'ostrum 

 curved, moderately stout, shorter than prothorax. Antennce 

 moderately stout; scape inserted nearer apex than base of rostrum 

 and passing apex; two basal joints of funicle elongate; club ovate, 

 free. Prothorax feebly transverse, ocular lobes feeble and 

 rounded, constriction slight, base bisinuate. Scutellum absent. 

 Elytra large, shoulders rounded, apex acuminate, sides declivous. 

 Pectoral canal deep and moderately wide, terminated between 

 four anterior coxse. Alesosternal receptacle raised, semicircularly 

 emarginate in front, rounded behind, cavernous. Metasternum 

 short, episterna concealed. Abdomen large, two basal segments 

 soldered together in middle and two-thirds of total length; inter- 

 mediates with deep sutures, conjointly considerably shorter than 

 2nd or 5th, below level of 2nd but not of 5th. Legs moderatel}' 

 long; femora moderately stout, very feebly grooved, the anterior 

 scarcely visibly dentate, the others edentate, posterior scarcely 

 extending to apical segment of abdomen ; tibite compressed, the

 squamose, punctate, apterous. 



The type and only known species of this genus is the Poropterus 

 porrigineas of Pascoe. It is separated from ForojJterus on 

 account of its grooved femora and the basal segments of abdomen 

 being soldered together; from Paleticus by the shorter tarsi, base 

 of elytra not trisinuate, straight tibise, itc.
