P. coGNATA. — On one occasion only have I taken this 

 species — a female, July 23rd, 1904, at Byfleet Canal, Surrey. 

 Folkestone, Kent, is another locality ; while McLachlan thought 

 it was most frequent in the New Forest. Perhaps it is a later 

 insect than the other two. 



Although it involves a considerable amount of repetition, I 

 have given the list almost without condensation in order to 

 shew the time of the year when the imagines appear to be most 

 frequent. Perhaps other naturalists may be able to supply 

 similar dated locality lists, and so add to our knowledge of the 

 distribution and period of flight of these insects. 



"' Almost immaculate, the chief markings being a black apex to all the 

 wings, and a spot on the costa at the pterostigma.
