succeeded in finding one. There is little doubt but that the larvae 

 pupate in hedgerows, maybe on the stems and branches of the 

 hedges, and very probably low down amongst the entangled under- 

 growth, which would render the pupoe the greatest protection and 

 extremely difficult, if not practically impossible, to find. — F. W.

Aglais URTiCiE, AB. — The pale variety of A. urticce which Mr. 

 Richardson records in the ' Entomologist,' p. 15, as a new aberration 

 is a well-known form of occasional occurrence ; the ground colour 

 may be described as pale straw-yellow. A similar type of colour 

 variation is also occasionally found in Polygonia c-alhiun and other 

 species. — F. W. Frohawk. 



Notes on Emmelesia unipasciata. — I think one reason why 

 this species has been overlooked in many localities W'here it probably 

 occurs is on account of its very retiring habits in its perfect state. 

 I was several years at Dovercourt before I thought of looking for its 

 larvae, and then one day in the early autumn, while I was out 

 collecting, I noticed some patches of Bartsia growing by the road 

 side, and picked a good handful of the ripening seed-heads, and when 

 I got home placed them in a large biscuit tin with a couple of inches 

 of silver sand on the bottom, and covered the top with muslin 

 instead of its own lid. A few days after I noticed several larvae 

 crawling on the muslin, and at the end of November I examined the 

 sand and found three or four dozen cocoons composed of the grains 

 of sand neatly and compactly spun together just below the surface ; 

 and the following summer a number of the moths w^ere bred. Since 

 then I have found these larvae in many places in the Harwich district 

 — in fact, wherever Bartsia was growing — but I never once met with 

 the perfect insect, although I was often " mothing " at dusk in|the 

 localities where the larvae were taken, and at the time of year when 

 they should have been on the wing. — Gervase F. Mathew^ ; Instow, 

 N. Devon, January 8th, 1918. 



Notes from North Wales : a correction. — In my note in the 

 last number of the 'Entomologist,' p. 18, the plant on wdiich the Pieris 

 brassiccB larvae and Psylliodes viarcida were feeding was misprinted 

 Sesile maritima. It was, of course, Cakile maritrma, and this is what 

 I wrote. Seseli (not Sesile) maritifna is a quite different plant. In 

 the same note Llyn Crafuant is a misprint for Llyn Crafnant. —

Peronea cristana in Hainault Forest.— In my recent paper 

 on this species I say (antea, p. 10) that I have been unable to find 

 any record of the forms that were formerly found in Hainault 

 Forest. I have now, however, succeeded in tracing what I suppose 

 must be a fairly complete list of them. It is to be found in the 

 ' Zoologist ' for 1846. pp. 1228 and 1516, and is contained in articles 

 by two well-known micro-lepidopterists of that day, H. J. Harding 

 and Wilham Hindley. The list is cristana, type ; also profanana, 

 sevmistana, striana, substriana, brunneana, sj^adiceaiia, vittana, con- 

 similiana, desfontainiana, fulvocristana, albovittana, fidvovittana, 

 bentleyana, fulvostriana, cristalana, subcristalana, subvittana, insu-
