were lively enough, and spread themselves freely over the neighbouring fields, 

 though their numbers in the original locality were still amazingly great.— C. T.

An alhinic variety of Cwnonympha Pamphilus, L. — A young friend, Mr. H. A. 

 Parsons, has just brought in for my inspection a variety of Coenonympha Pamphilus , 

 L., which he had the good fortune to take in July last, near Studland, Dorset. In 

 it the whole upper surface of the fore- and hind-wings has its usual fulvous colour 

 replaced by creamy-white ; the usual discal dot and narrow marginal stripe re- 

 maining brown, though but faintly so ; the under-side of the fore-wings partakes of 

 the creamy-white tint. So complete a case of albinism is exceedingly rare in this 

 species. — Chas. GL Barrett, Tremont, Peckham Rye : September 3rd, 1902. 



On the fight-time of Argyresthia Atmorielln, Bnks. — In a note published in 

 the Ent. Mo. Mag., Ser. 2, xii, 200 (1901), I mentioned that the only specimen of 

 Argyresthia Atmoriella that I had seen on the wing of its own accord was flying 

 briskly at 7.40 p.m. (i. e., about 40 minutes before sunset) on June 21st of last year. 

 I have not worked specially for the insect this season, and have only met with two 

 or three examples of it, but one of these, a rather worn female, was netted while 

 flying backwards and forwards close to a branch of larch at 8.5 p.m. (i. e., about a 

 quarter of an hour after sunset), on July 28th. Tlie moth was obviously indulging 

 in a voluntary flight, which was of such an oscillating character that I have little 

 doubt that the insect was intent on finding a suitable place for ovipositing on the 

 branch to which its attention was directed. In view of the particularly sluggish 

 nature of the species, these two instances seem sufficient to prove that its natural 

 flight-time is from rather before to rather after sunset. July 28th is an exceptionally 

 late date for the insect to be still about : last year (after a cold late spring) I took 

 it from June 7th— 21st, but this season seems as prolific in record late appearances 

 as 1893 waB in record early ones. — Eustace R. Bankes, Norden, Corfe Castle :

Psammotis pulvera/is, Hb., in the Isle of Purbeck. — In Ent. Mo. Mag., ser. 2, 

 x, 289, I chronicled the capture in 1899, by a young friend, of a worn specimen of 

 Psammotis puhwralis in this district, and it is highly satisfactory to be able to 

 record the fact that a few other examples have, in the course of this and last seasons, 

 been taken in the same spot (which is one of very restricted area), and that the 

 species, which is of such rare occurrence in Britain at the present time, is evidently 

 established there. Last year, at the end of July and beginning of August, a friend 

 and I, favoured by particularly fine and hot weather, secured between us eight 

 specimens (viz., seven males and one female), but this season, in spite of several 

 visits to the locality, the only specimen that has been seen is a male that I captured 

 on July 28th, and there seems now but little likelihood of others being met with. 



The imago is easily disturbed from among the herbage, &c, at any time during 

 the day, and its flight is slow and weak : in size and habits it closely resembles 

 Ebulea crocealis, Hb., which occurs in the same spot, and at the same time, but
