This species is subcylindrical, with the anterior part of the body 
attenuated. The head is scarcely so broad as the front of the pro¬ 
thorax, its anterior margin is acute and emarginate, its lateral 
margins, as far as the eyes, nearly parallel; an impressed line 
extends from the middle of the clypeus to the crown, which bears 
two small elevated curved ridges, which somewhat resemble a horse¬ 
shoe, the intermediate space with two minute tubercles. The 
maxillary palpi have the second joint very much dilated, but with 
the apical internal angle not salient; the terminal joint of the 
labial palpi very slender. The antennm have the clava compressed, 
oblong suhtrigonate, with the anterior or lower margin acute, and 
the posterior or upper one dilated and boat-shaped, or excavated 
into an oblong-oval cavity, filled with pale coloured membrane, and 
having each of its margins scalloped, each scallop marked with an 
impressed dot; the basal angle is produced into an acute point. 
The prothorax is bipartite, the centre very deeply excavated, the 
anterior portion with the margins acutely angulated, and with its 
middle part dilated behind and emarginate; the hinder part has the 
sides in front considerably elevated and also angulated within. 
The elytra are black, suhopaque, with the base and narrow apical 
margin of brick-red; the disc with minute luteous scales, and their 
sides with rigid setm standing out at right angles from the body. 
The feet are elongate and slender, the posterior tibim being more 
dilated and with the tips narrowed. The tibial calcaria are obsolete. 
The extremity of the abdomen is furnished with two incurved 
fascicles of hairs, and the anal segment is destitute of the two 
curved horny points. 
The observation of Latreille upon this species (the name of which 
he unnecessarily altered to triponicornis^^ “ P. lineato proximus et 
forte varietas elytris latius nigris,''’ appears to me to be incoiTect, 
that species belonging as I imagine to the second section, and in
