PTEROPHORI. 175 



Edlington Wood (G.T.F.) ; Huddersfield ((5.7:/'.) ; 

 Richmond (_/; Sa//g) ; Scarborough {Sfaiiiton's Manual); 

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



Pterophorus parvidactylus Haw. Stainton's Manual 

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

 have ever seen a Yorkshire specimen. 



Pterophorus phaeodactylus Hilb. 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 Zell. = bipunctidactylus Haw. 

 Plentiful in old pastures, &c., where its foodplant (Scabiosa) 

 grows freely. In some old rougli fields adjoining Lejtton 

 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 Fi'sdi. 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 zophodactylus F>up.=Loe\N'\\ Zdl. Larva; 

 on flowers of Erythma early in August. 



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

 {W.F.).
