distinct. Posterior coxae small, at the sides of the body and very- 

 remote. Tarsi densely pubescent beneath, with the basal joint elonr 

 gate; third strongly dilated, deeply bilobed; fourth long, slender; claws 

 moderate, free. Metasternal side-pieces narrow but distinct, the suture 

 much deeper behind. 



The mentum is loosely articulated with a narrow and rather 

 prominent basal support or peduncle; it is rather small, nearly 

 flat, slightly wider than long, narrowed from apex to base, the 

 posterior portion parabolic, the apex broadly angulate, the 

 angle slightly thickened and tumid in the middle; at the sides 

 the maxillae are partially exposed, much more widely so toward 

 base. The genal emarginations are small, but rather deep; the 

 mandibular scar rather large and prominent, rounded. 



The antennal grooves have a certain tendency to descend as 

 they approach the eyes, but this is very slight, and, as the 

 general appearance is decidedly that prevailing in the Otiorhyn- 

 •chini, I. have there assigned it a place among the Trachyphloei, 

 although it is one of those forms the position of which must, 

 under the present system of classification, be more or less doubt- 

 ful. It appears to possess considerable affinity with Agasphae- 

 rops Horn of the Brachyderini, another genus of doubtful 

 position, but differs in the size of the mentum and in antennal 

 structure. 



The single species is rather densely covered throughout with 

 somewhat long erect cinereous setae, these not being regularly 

 arranged on the elytra, and the general sculpture is very similar 

 to that prevailing in Amnesia. 



P. seto§u§ n. sp. — Oval, convex, black; legs and antennse fuscous; 

 entire body covered with a thin indument, composed of small, closely 

 adherent scales which do not overlap, with some pale scattered scales 

 -at the sides of the prothorax and elytra. Occiput convex; front flat; 

 beak flat, apex truncate, not distinctly angularly impressed; entire 

 surface finely granulose, the granules well separated, and each formed 

 by a thickened scale. Prothorax broadly convex, nearly one-half wider 

 than long, widest in the middle; sides strongly arcuate, broadly rounded 

 anteriorly, feebly convergent, and nearly straight toward base; the latter 

 broadly arcuate, fitting against a corresponding emargination in the 

 base of the elytra; apex broadly emarginate, about two-thirds as wide 

 -as the base; disk coarsely, densely, and strongly granulose, each granule 

 punctured and bearing a long erect seta. Elytra oval, convex, widest 

 at anterior third ; apex strongly declivous and slightly inflexed, four- 

 fifths wider than the prothorax, one-third longer than wide, rather
