liibited Psilnra monacha from the New Forest, and made the following- 

 remark s : — "This species seem to liave shown— at least in our experi- 

 ence — a greater tendency to the production of banded forms in 1893, 

 tlian in the preceding season ; and the more frequent occurrence of dark 

 varieties in certain seasons has previously l)een commented on l»y ]\Ir. 

 Tutt. At least five, including exannjles of both sexes, of those cajjturcd 

 in 18'Jo, show this condition, and one 5 in particular lias an almost 

 solid black median band across the fore wings. It will be noticed, too, 

 tliat this si)ecimen is much below the normal size. Now, amongst those 

 taken in 1892, only one or two show a deviation from the type in that 

 direction, a,nd the deviation is slight. All those exhibited were taken 

 cither as imagines or as pui)a\ In 1893, the larvie were sul>jected to 

 the long drought which had been almost total for four months previous 

 to the appearance of the perfect insect. They must also liave experi- 

 enced, both as larva^ and pu}>a', great alternations of temi)eratui-e — hot 

 sunny days and cold nights. The date of appearance varies considerably 

 in different years; in 1892 and 1893, the species .was well out at the 

 end of June, whilst in 1891, several fresh examples were taken at tlic 

 beginning of September. The $ appears to be very we.dv winged — 

 a condition Avhicli seems often to obtain in families containing species 

 Avith a[)terous J s." — Mr. Smith said that he had bred AmphidiiHiin 

 slrataria on the 1 8th inst. from New Forest larva. Mr. liattley reported 

 that Brephos partlienins was just coming out at Theydon, and that 

 A.^jjlKilia fiariconiis was getting worn. lie had also found TdeniocaiiijHi 

 viimdfi, common, and T. rriuhi swarming on tlie sallows in the same 

 locality, and had taken one T. popidfti. Mr. Frout tlien I'ead a paper

A coKKECTioN. — Mr. Jenuer Weir, who Avas a personal friend of tljc 

 late J. F. Ste})hens, informed me, shortly before liis death, that tlie 

 latter lived not at Eltham, but at Fltham Cottage, Kennington. — F.

All tlirough the history (^f entomological nomenclature there lias 

 been a recurring tendency, on account of their great su})erticial similarity, 

 to unite these two as oiie species, and it was the desire to obtain inde- 

 pendent evidence on the (piestion of their identity or distinctness, liy 

 breeding Ijoth forms from the egg, Avhich tirst led me intcj the study of 

 them. After breeding each species several times, and communicating 

 Avitli several entomologists avIio had information to impart on the 

 subject, I Avrote a somewliat tentative article, Avhieh a|i[)eared in the 

 Ent. Bee. of July, 1892 (vol. iii., p. 150). jNIy own personal opinion 

 Avas at that time, wliat Jiasj since been jiroved correct, that Ave had two 

 quite distinct species to deal Avith, and that the seeming contradictions 

 Avere to be reconciled thnuigh the existence of a red form of nnidentdnd, 

 HaAV. so like fernKjuriii, Haw. as readily to be mistaken for tliat, 

 species.
