PTEROPHORI. 175 



Edlington Wood {G.T.F.) ■ Huddersfield (6^.7:7'.) ; 

 Richmond (y; Sang); Scarborough [Staintoji's Manual); 

 York, common at Sandburn ( W.F.). 



Pterophorus parvidactylus Haia. Stainton's Manual 

 gives Scarborough as a locaHty, but I do not know that I 

 have ever seen a Yorkshire specimen. 



Pterophorus phseodactylus Hiib. Hobkirk's 'History 

 and Natural History of Huddersfield ' gives this species 

 as having been taken at that place, but I think this is 

 most probably an error. 



Pterophorus serotinus Z^//. = bipunctidactylus Haw. 

 Plentiful in old pastures, &c., where its foodplant {Scahiosa) 

 grows freely. In some old rough fields adjoining Lepton 

 Great Wood, Huddersfield, it occurs in great profusion, 

 but within a radius of some miles round the town this is the 

 only spot I know where it can be found. On this ground 

 in 1882 I took it continuously on the wing from June 12th 

 to October 14th, thus showing the imago to be out for 

 over four months.

Pterophorus plagiodactylus -Flsc/i. Only recorded from 

 Sandburn, York, by Mr. W. Prest, but I have no doubt it 

 is often confused with the preceding species. I am quite 

 satisfied myself indeed, and Mr. C. G. Barrett is of the 

 same opinion, that it is merely a form, and a scarcely 

 distinguishable form, of F. bipunctidactylus. 



Pterophorus zophodactyl us Z>///.=Loewii Zell. Larv^ 

 on flowers of Erythrcea early in August. 



Bramham {J.S7n.); Sandburn, York, in 1877, rare 

 ( W.F.).
