LEPTURIDiE. 179 



DESCRIPTION. 



This is the American representative of P. quadrimaculata, from which it differs principally in 

 being not so hairy, with hoary instead of yellow-tinted hairs: the punctures of the prothorax and 

 elytra are more minute; the antennas are rather shorter, and the elytra, instead of two subquadran- 

 gular black spots, have three less black linear ones, the two anterior ones being partly parallel, and 

 in some specimens confluent.
