CAPTURES AND FIELD REPORTS. 10 



and the last July 19th. Of the forty-nine specimens reared, twenty-six 

 were males and twenty-three females: nineteen males and seven females 

 had red hind wings; seven males and ten females had orange hind wings; 

 and six females had vfllow hind wings, Let me strongly advise those who 

 have larvne this year not to feed them on dandelion or groundsel. —

Notes on the MACRO-LEPiDoprERA of the Conway Valley, North 

 Wales, — The clitf-like line of hills which form the boundary of the Vale 

 of Conway on the west side is broken at intervals by various valleys and 

 glens, down which rush the tributary rivers and streams from the lakes and 

 pools of Eastern Snowdonia. In most of these insect life seems more 

 abundant than in the wider strath of Conway itself, which I attribute to 

 their freedom from the floods which occasionally submerge the low-lying 

 Conway vale ; and as I was living at the bottom of one of the most 

 picturesque of these little valleys the greater part of last spring and 

 summer in order to fish the Conway, and the Cwlyd and Crafnaat lakes, I 

 made the following notes on some of the I^epidoptera that I met with during 

 walks and hours not devoted to angling. The glen in question, though only 

 about two miles in length from where the stream rises out of one of the 

 larger lakes to where it ruslies down by a series of cascades into the Conway, 

 presents a diversity of physical features, as the water runs from a moun- 

 tainous and moorland region at the top of the valley through thickly-wooded 

 dells of fir, oak, birch, and alder, into the meadow-land at the bottom; and 

 this would naturally be favourable to a variety of lepidopterous insects, as 

 the altitude varies also from 00(3 feet at the lake, with the hills on either 

 side rising to 1000 feet, to nearly sea-level at the tidul reach where the 

 stream jonis the Conway. Among the Rhopalocera I found Pieris rapcc 

 and P. napi both abundant; but 1 did not observe many P. brassicte until 

 late in the season, when they became very numerous. On July ;31st a small 

 meadow of uncut grass and wild flowers was full of them, mostly at rest on 

 the flowers. — Euchloe canlamiiies was abundant. — Argijnniseuphrosijne more 

 or less common all over the central and woody portion of the glen ; but as 

 long as they were "out" they were always collected in vast numbers in a 

 little glade covered with small furze and alder bushes, where I could obtain 

 any quantity without moving from one spot ; here on May 8th they literally 

 swarmed. — A.sclene, common, but nothing like the numbers of the preceding 

 species. — Vanessa io, hybernated specimens very plentiful in the spring, and 

 most of them in excellent preservation. I did not see many of them in the 

 autumn ; but the continuous rainfall would account for that, as it did for the 

 scarcity of V. atcdanta, of which I only saw two. — V. urtica, common. 

 — V.c-album, plentiful, especially hybernated specimens; but I took five 

 splendid ones in two adjoining meadows on Sunday, August 2nd. The rich 

 velvety gloss of the black spots on the wings seem to fade soon after death. 

 — Pararrje e<jeria, common everywhere in the valley during the latter part of 

 the season, but the earlier broods were very local; for weeks I only found 

 them in one spot. — P. mcgara swarmed everywhere; it was without doubt 

 the commonest butterfly in the valley. — Epinephele ianira, common ; 

 E. tilhonus, E. Iiyperanlhns. I took a few specimens of each. — Cceno- 

 injmpha pCDiiphiliis, Polyommatus phlccas, Lyccena icarus, all abundant. — 

 Tliecla rubi, common on the moors at the top of the glen. — L. aryiolus, one 

 or two. — Niso7iiades tages and Hesperia sylvanus, both very common. 

 Heterocera. — Smerinthus popuU, found four: one on a path, May 5th;
