SOME UNDESCRIBED .\BKRK\TION.S OF AMGKRONA PRTINARIA, LINN. 1 19 



the dried leaves which had h'en phieed in the hai^s. Diu-iiiif Januarv 

 of this year these larvio were exposed to hard frost from the llth-17th, 

 and, on examining the bags again at the end of February, I found 

 many dead, others looked shrivelled, but probably they were healthy and 

 harmonised better with their surroundings thus. They formed, how- 

 ever, quite a contrast to the two broods in the greenhouse, which were 

 larger, their coats much smoother, and altogether more healthy-look- 

 ing, whilst I did not find a dead larva. This experience leads one to 

 surmise that many must die in nature, and that, in confinement, success 

 is better obtained by protecting them during the inclement w^eather. 

 At any rate, it appears that this must be done if one wishes to breed 

 the characteristic large race that is obtained in confinement, a race 

 altogether superior in size to the examples obtained in nature. 



Some undescribed aberrations of Angerona prunaria, Linn. 



Bj L. B. PROUT, F.E.S. 

 In working out this species for his recent paper, read before the 

 City of London Entomological and Natural History Society, on 

 March 3rd, my friend Mr. C. P. Pickett, F.E.S., called attention to 

 tW'O interesting and distinct aberrations which appeared amongst the 

 material he had bred, and which, so far as he could ascertain, had 

 never yet been named ; but, in order to avoid the rashness of which 

 our editor and myself have several times complained recently, 1 under- 

 took to look into the existing literature of the variation of this species 

 before proceeding further. I am now in a position to say that the 

 forms in question, and one other striking aberration, are still unde- 

 scribed, and I here subjoin diagnoses, besides noting briefly the pre- 

 viously-named forms. Mr. Pickett will be able, if he think necessary, 

 to add further details about these forms, of w-hich 1 give merely the 

 briefest possible description. 



1. Pruiiarid, liinn. — ^The type tonu, as is well-known, is uniformly fulvous in 

 the cf , luteous in the ? , spotted with fuscous dashes. Linne's type s is extant, 

 and agrees with his diagnosis. Scopoli's corticaiis {Ent. Cam., p. 216), described 

 as bone-coloured, seems to be a typical ? . 



2. ('(inilaria, Thiib. (^mrdiatu, Fuessl.,e,r err., «fc'Linn.). — ^\'iugs infuscated, 

 excepting a median band on forewings (not reaching to inner margin) and a part 

 of the hindwings, which retain the original ground colour. 



3. Spati;ihi-r(ii, Lampa. — 1 hiicolorous, without the dark freckling. Lampa 

 described this from the 9 , and 1 have only seen it in that sex (one in Br. Mus. 

 Coll., from Central France), but I understand it does also exist in the c? . 



4. I'tnroloraria, Horm. (ab. et var.), cf .—More unicolorous than the type, 

 with only a few indistinct grey dots, and sometimes a darkened outei- margin. 

 Staudinger wrongly unites this Bucovina form with var. kentearia ; if it be not 

 distinct from all the others, it must be united with ab. spaiuibergi, as the ^ of 

 that form. 



5. K"ntcinia, Stgr. = j.!7n)«r/, Fuchs (var.). — Smaller, paler ( cT pale ochreous, 

 ? whitish), densely irrorated with fuscous. This forms a local race in some parts 



of Asia. 



6. Canntirpataria, Fuchs (ab.). — A casual j aberration of var. keittearia, 

 having the whitish colour of the ? . 



7. Pickettariu, n. ab., i , ? . — Basal area dark, as in ab. corj/laria, but its 

 costa narrowly of the typical ground-colour ; central area of the ground-colour, 

 except the extreme iiujer margm, which is very narrowly fuscous ; marginal area 

 consisting of narrow fuscous band, pyramidal, its base at inner margin, its apex 

 (rather ill-defined) just above uervure 6, this band followed by a narrow area of 

 ground-colour. Hindw ings distinguished from those of ab. corylaria by having a 

 blotch of the ground-colour at apex. 



8. Pallidaria, n. ab., j , ? . — Freckling absent, as in ab. uparujbcr'ji, but the
