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 ; antenna) about half 
as long as the body, terminal joints strongly thickened, as broad 
as long. Thorax subcylindrical, 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 appeudiculate (in some European species 
simple).

Piceous with aeneous gloss, clothed with whitish scales ; antennas 
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 aeneous gloss. In well preserved specimens 
the elytra have a number of small whitish pubescent spots. The
