Tlie second tergite is longer and more narrowed to the base 

 than in P. coryplueus, Grav., and other Palajarctic species, 

 the first tergite is also much m )re slender; otherwise the 

 species does not differ in any important structural point. In 

 these points it comes very near to P. ustulus, Grav., which 

 appears to be its nearest ally.
