while the medial line is only perceptible towards the base. The 

 elytra are coarsely punctured in rows, the interstices being com- 

 posed alternately of single and double rows of setigerous granules, 

 so closely placed as to give a ribbed appearance to the elytra, 

 the " setss " being here as well as over the whole body of a 

 cinereous hue. 



The anal appendage of the male is strong, and considerably 

 longer than in P. mirabilis. The female is not known to me.

I am not quite sure that the insect which I have marked 

 in my cabinet, P. mirahunda, is the same which Schonherr 

 has described, it is however certainly very near it. If I am 

 right in my supposition as to the species, the knife-like process 

 on each branch of the anal forceps is prolonged downwards to 

 a considerable degree. 



I cannot find any indication of the habitat of this species.
