Aplecta herbida. At York by Mr. Prest.

Scoparia basistrigaiis. I again took this species in 

 Edlington Wood on July 31st, but not so freely as in the previous 

 year.

 in August by Mr. Prest. 



S. coarctalis. Taken at Blake Lee, Marsden, at the 

 Union's Excursion there on Bank Holiday, August 2nd.

VARIETIES, ETC. 



Usually Yorkshire is well represented in extreme aberrations, 

 but. this year there has evidently been a dearth, as we have heard 

 of no extraordinary forms having turned up. In spring the 

 unicolorous very dark form of Hybernm progetnmaria was again 

 common at Huddersfield, and Mr. S. L. Mosley has named it 

 variety fuscata. Mr. Richardson says it also occurs freely in the 

 Wakefield district. A very dark olive, in some cases nearly black 

 form of Phigalia pilosaria too, appears to be getting commoner ; 

 several occurred at Leeds to Messrs. Smethurst and Henry Marsh, 

 and also rather commonly at Bradford to Messrs. J. W. Carter 

 and Hodgson. Another interesting discovery I made through 

 correspondence with Mr. W. F. Kirby, is that the form of Polia 

 flavocinda which is abundant in the Huddersfield district, and no 

 doubt in other parts of the county, is not the ordinary type of the 

 species, but the variety ineridionalis of Boisduval, a variety which 

 had not previously been recorded as occurring in Britain at all. 

 A somewhat analogous case occurs in Scoparia Zelleri. It is now 

 generally admitted that this is merely a variety of Scoparia ce?!ibrcE, 

 and singularly the Huddersfield specimens, of which I have taken 

 many hundreds, seem to be nearly all of the form Zelleri, the few 

 exceptions being still another variety, viz.: — Dr. F. B. White's
