258 ' [April, 



many of our butterflies is mainly due to undefined natural causes. Stephens, in his 

 "Illustrations" (Raust., i, p. 27, 1827) says, that in June, 1810, he saw A. cratcegi 

 in plenty in Coombe Wood, and that on the following year he captured several at 

 Muswell Hill, but had since never seen it at large, and he adds that Mr. Haworth 

 used to constantly take it at Chelsea. The " Cabbage Whites " are notoriously 

 migratory, and immigration no doubt frequently recruits our already too-abundant 

 supply. — Eds.] 



Oh the Ufe-Mstory of Depressaria cinifloneUa, Z. — In March, 1885, I received i| 

 fi'om Mr. Salvage, then collecting at Eannoch, some living females of this species, ; 

 with the information confirming a previously formed guess of my own, that the larvae 

 would be likely to cat birch leaves. One of these moths laid about a dozen eggs, the 

 greater part of them in a row along the crevice between a birch bud and the twig ou 

 which it grew, fastening them to the scales of the bud. When I first saw these eggs 

 they were very bright red, and became, a few days before hatching, dark smoky- 

 purple in colour. The young larvae appeared during the last half of April, and took 

 readily to birch, Betula alba. The following description was taken on May l2th : — 



Length, about ^-in., tapering towards both ends ; head dark brown ; corselet 

 almost black, bisected by thin median line ; anal segment with black plate, and large 

 black spots on anal claspers ; body, dull sage-green, the spots large with black bristles. 



On May 2oth, being about full-grown, they were again described, thus : — j 



Length, about f -in. ; head pale reddish, marked with dark brown about the 

 mouth ; corselet and anal plate blackish ; body purple-brown, rather lighter 

 anteriorly ; spots, large and black. By June 8th the larvte had pupated. The pupa 

 is about -iQ-m- long ; the colour of the body red, that of the wing-cases olive-brown, 

 with a greenish tinge. 



The larvae live in a tube open at both ends, formed by turning down a piece at 

 the edge of a birch leaf, or by folding one down the middle. The moths emerged 

 towards the end of June, and were, on the average, larger than wild specimens from 

 the same locality, from which I conclude that birch is almost certainly the natural 

 food-plant of the larvae. — W. H. B. Fletchee, Fairlawn House, Worthing :

Remarkable variety of Eudorea pi/ralella.- — In the end of June, 1886, when 

 collecting on our Isle of Purbeck coast, I was fortunate enough to meet with four 

 examples of a most beautiful and striking variety of Eudorea ])i/rale!la. The fore- 

 wings are pure white, and, with the exception of a few coloured scales at the base, 

 and a small wedge-shaped blotch and dotted line at the extreme hind margin, tin 

 only markings are contained between the first and second lines, and are of the usual 

 type and colour : the space enclosed by these lines shows out against the clear white 

 ground colour as a well-defined and conspicuous central fascia. There is not the i 

 faintest trace of any subterminal baud. 



Between the typical E. pi/ralella and this extreme form, which exactly corres- 

 ponds to, but is even whiter than, the very whitest examples of E. frequentella, var. 

 portlandica, the local coast variety ingratella is an intermediate link. 



These four specimens of this pale variety were all I could meet with out of 

 numbers of the usual type. — Eustace E. Bankes, The Eectory, Corfe Castle
