88 THE entomologist's record. 



continental larvfe, emerged on July 30th, 1908, and reminded one 

 strikingl}' of P. dejeani (of Java) by exhibiting creamy-yellow (somewhat 

 browned) bands and a remarkably colourless yellowish underside with 

 pale greyish-violet (instead of blue) markings on the forewings. The 

 specimen diflered from dejeani, however, in the ground colour of the 

 upperside, which was brown-black, with a reddish flush instead of light 

 bronze, but, as is well-known, normal examples of P. atalanta often 

 exhibit a ground colour of shining bronze, so that the detail is 

 evidently also inherent in the species. A week later, two aberrations 

 bred from wild Herts larvas, emerged on August 7th, one of which was 

 transitory to P. indica in the facies of the underside forewings, the 

 blue markings being especially well-developed in this sense. Doubtless 

 also these blue indica-iovm markings are very near to those in 

 P. tatumecunea. The other aberration, a progressive form, appeared 

 unlike any existing species by exhibiting on a deep black ground colour 

 beautiful rose-coloured bands, shaded with white near the costa of the 

 forewings, and interrupted by black in the median part. The blotches 

 in the apex of the forewings are pure white, and whitish scales seem 

 mixed up with the black ones in the ground colour, making the speci- 

 men look abnormally transparent when held against the light, in which 

 case, also, the rose bands appear almost mauve-coloured. Near the 

 inner margin, and close to the bright band, there is a whitish blotch 

 or suffusion, and this is a detail which often occurred in other aberra- 

 tions of P. atalanta which I bred. On the hindwnngs, one of the 

 median ocelli is centred with white on the upperside, reminding one of 

 ab. )iu'rrifieldi, but these whitish spots occur also in ab. klemensiewiczi^ 

 Schille. I suggest the descriptive name ab. rosea for this aberration, 

 which made a beautiful and uncommon spectacle when flying. Several 

 specimens that emerged later exhibited brilliant scarlet bands, which 

 on the hindwings were nearly 6mm. broad, and had only very small 

 black dots close to the margin, reminding one of the parallel development 

 in P. taimneamea. Other specimens had orange-yellow bands, and 

 the apical spots tended to bluish-violet. An aberration of this (pro- 

 gressive) class with pure lilac-coloured apical spots, but normal under- 

 side, is in the British Museum coll. In two otherwise almost typical 

 specimens the shape of the blue markings in the underside forewings 

 suggested a " ring," as in P. itea and P. (/onerilla, and, in a third 

 specimen, the blue formed a compact patch. Two specimens 

 had fewer white spots in the apex, and showed a red spot on the 

 underside near the inner margin and in the centrtil area of the fore- 

 wings, thus approaching the markings of P. indica in these respects, 

 and a few also showed well-known rusty-red markings between the 

 white apical blotches. On August 19th last, T reared from among 

 Lancashire larvaB an aberration which was sun-bred, and emerged 

 twenty days after pupation. The upperside exhibited a deep black 

 ground colour with rich brown-orange narrow bands. The bands on 

 the hindwings were abbreviated, showing only three instead of four 

 (or five) black spots, of which the one next the anal angle is blue 

 centred, while the third is wedge-shiiped, and nearly touches the black 

 ground colour. The underside of the hindwings was of an exception- 

 ally dark brown colour, much suft'used at the base Avith violet, and 

 violet- white spots mark the centres of the median ocelli (an atavism !) 

 which Avere partially disintegrated. The forewings (underside) showed
