Although this species closely resembles the P. communis^ still 

 it is very distinct ; the form of the head alone Avould serve to 

 distinguish it; and it should be observed that the markings are 

 not yellow, but really cream-coloured. This species occurs near 

 London, and has been taken in Hampshire; Mr. S. Stevens met 

 with it at Arundel, Sussex.
