126 THE entomologist's record. 



conspicuous being a male with the coloration of the female, and a 

 female with the coloration of the male. I have seen many notices of 

 the former variety, but not of the latter. I shall be glad to learn 

 whether any collector has had the same fortune as myself — T. Willson, 

 2 2, Halford Terrace, Richmond. February T^rd, 1892. [There are 

 several records in our old entomological literature, and most of our 

 larger collections contain such. I took a perfectly yellow male of this 

 species at Wicken last year, and a Dundee collector gave me a dark 

 male-coloured female some years since. — Ed.] 



TiENiocAMPA POPULETi var. NIGRA. — Last spring, Dr. Chapman sent 

 me some ova of T. populeti which had been laid by a dark ? . There 

 were about a dozen to begin with, from which I bred nine, all dark ; 

 two were especially so, as dark as ordinary Rusina tenebrosa, and neither 

 Drown nor grey, the markings hardly visible. Three others had similar 

 tendencies but were not of so decided a colour, and the remaining four 

 were also dark, but suffused with a red brown colour about the middle 

 of the wings. There was not one of the ordinary grey type. — E. W. 

 BowELL, Sissinghurst Vicarage, Staplehurst, Kent. April, 1892. 



Argynnis SELENE VAR. — I have a specimen of A. se/ene taken at 

 Brockenhurst in 1890 which is somewhat analogous to the vars. of V. 

 urtica mentioned by Mr. Sharp {Ent. Rec, p. 8), and Mr. Baton 

 {Ent. Rec. p. 57). All the brown markings on both upper and under 

 sides are replaced by white, while the black and silver markings remain 

 intact. The specimen was in fair condition and so could not have 

 been " worn," to have this appearance. Has any theory been started 

 to account for this failure of the pigment cells? Does it bear any 

 analogy to "albino" specimens of blackbirds, mice, rabbits, etc. — 

 A. W. S. Fisher, The College, Winchester. [The failure of pigment 

 development is somewhat fully discussed in the " Introduction " to The 

 British Noducz and their Varieties, vol. ii. — Ed.] 



AsPHALiA FLAVicoRNis VAR. — A curious Specimen of A. flavicornis 

 emerged yesterday (March i8th) in my cage, bred from larvae obtained 

 in the New Forest. There are hardly any signs at all of the usual 

 transverse lines, but a large number of black scales are suffused over 

 the green ones, especially near the base and apex. But, most curious 

 of all, there are two longtitudinal black streaks on the costa, about a 

 quarter of an inch in length and slightly curved, the concave side being 

 towards the costa. There is nothing else unusual about the specimen, 

 except its small size, just under i" 3'". — Id. [Does not this resemble 

 the northern type, described in British Noctiice,\&\.c., vol. i., p. 5 ? — Ed.] 



Var. of Noctua rubi. — Whilst sugaring one evening last July, at 

 Askham Bog, near York, I took from amongst a number of typical 

 specimens, a pale yellowish ochreous form of Noctua rubi, in fine 

 condition. In the collection of Mr. T. AUis, in the York Museum, 

 I notice that there are two specimens of this form. — W. Hewett, 

 York. 



Seasonal forms of Pieris napi. — In the Entomologist's Record, etc., 

 for March, p. 69, there is an account of the exhibition, at the meeting 

 of the City of London Entomological Society, of an intermediate form 

 between Pieris rapce and F. napi, in which it is stated that "the under- 

 side of this insect was very slightly veined, though the upper surface 

 presented the characteristics of F. napi." This is an exact description
