 Distinct from P. persica by the shorter petiole and 

 differently shaped second abdominal segment. 



In P. persica the second abdominal segment is as broad at 

 the apex as its entire length, in P. escalerce it is one and a 

 quarter times as long as broad at the apex, and has an 

 altogether more slender appearance. 



The Avhole insect has a paler appearance, and is easily 

 distinguishable at a glance, though, were it not for a struc- 

 tural diflPerence, it might be considered a variety.

 testaceous.

Head broader than thorax, petiole long and slender, 

 broader along apical half, the whole about as long as the 

 thorax. Second abdominal segment cup-shaped, as broad as 

 the thorax at the tegulse, the width at apex about equal to
