Type, P. pilosus, Rossi, from Europe. 



Range. All parts of the world, except Australia. 



Elongate, nearly cylindrical, sparingly or moderately pubescent. 

 Head deeply inserted in thorax ; eyes small ; antennae about half 

 as long as the body, terminal joints strongly thickened, as broad 

 as long. Thorax subcyliudrical, nearly as long as broad, narrower 

 than the elytra, with distinct lateral margins, the anterior margin 

 rather strongly produced in the middle. Elytra generally punctate- 

 striate, the surface often clothed with scale-like pubescence or true 

 hairs. Prosternum oblong with deep grooves at the sides for the 

 reception of the antennae. Mesosternum short and transverse. 

 First abdominal segment as long as the rest of the segments 

 united. Legs moderately stout, pubescent or clothed with scales ; 

 intermediate and posterior tibiae more or less distinctly emarginate 

 at their apices ; claws appendiculate (in some European species 

 simple).

 p. 913. 



Piceous with aeneous gloss, clothed with whitish scales ; antennae 

 and legs obscure rufo-piceous. 



Head strongly punctured ; excavated between eyes ; clypeus 

 transverse, thickened at the base. Antennae about a third the 

 length of the body, terminal five joints fuscous. Thorax scarcely 

 broader than long, sides straight and diverging from base to 

 far beyond the middle, thence rather abruptly rounded and 

 converging to the apex, above convex, subcylindrical, deeply 

 punctured ; clothed with deeply bifid, narrowly oblong, adpressed 

 scales. Elytra broader than the thorax, convex, deeply excavated 

 below basilar area, deeply and coarsely punctate-striate, punc- 

 turation rather finer towards the apex ; surface clothed with 

 similar scales to those on the thorax, forming here and there ill- 

 defined patches.

The general ground-colour is piceous (not black as given by 

 Baly) with more or less asneous gloss. In well preserved specimens 

 the elytra have a number of small whitish pubescent spots. The
