 half way down the cheeks ; thorax and abdomen similar to those in P. ruricola ; 

 legs black ; wings with the outer cross veins sinuous, and less oblique than those in 

 the other species, the first (auxiliary branch) and third veins both spinigcrous ;

 setse ; legs black ; wings with the outer cross vein straight and very oblique, and 

 with the third longitudinal ciliated from the base to a short distance beyond the
