428 BRITISH LEPIDOPTERA. 



(3. ab. rosea, Bart., "Palaeark. Gross-Schmett.,"p. 176 (1900). — The somewhat 

 lighter, more yellowish -brown ground colour of the forewings, and the rose colour 

 of the hindwings are much more brilliant and widely extended than in the typical 

 specimens. According to Caradja, specimens of this aberration occur in Poland 

 among the type, but, as no material from that district lies before me for comparison, 

 I am unable to state whether these specimens reach the splendour of colour of those 

 which used for a long time to be brought into the market by the late Leipzig 

 collector, A. Kroning. According to him, the larvae which were fed on quince 

 (Cydo7tia vulgaris) produced the ab. rosea. Herr Hermann Gerber, of Stotteritz, 

 tried to produce the form, but always found that the larva? would not accept either 

 of the cultivated varieties of quince, but died soon after hatching. It is considered 

 that ab. rosea may only arise from artificial (chemical) influence on the freshly- 

 emerged moths (Bartel). 



This was evidently used for some years as a MS. name, e.g., 

 Caradja writes (Iris, viii., p. 65) : "The var. rosea occurs in Poland, 

 &c," at a date five years before Bartel diagnosed it. 



y. var. cinerascens, Stand., " Stett. Ent. Zeit.," xl., p. 316 (1879); "Cat.," 

 3rd ed., p. 99 (1901); Bartel, " Palaeark. Gross- Schmett.," ii., p. 176 (1900). — A 

 small S , much lighter than German specimens. The forewings are light ashy-grey 

 with few prominent markings ; beneath less red, almost suffused rosy, with a scarcely 

 apparent darker border. The ocellated spots of the hindwings are largely filled up 

 with milky-blue, otherwise agreeing with the type ; the underside of the hindwings 

 also has the marginal areas very weak. The specimen at first sight appears to be a 

 new species. If all the S. ocellata occurring in the Nariin district are as pale as 

 this, they must be recognised as a local form, and could then be known as var. 

 cinerascens (Staudinger). 



In his Catalogue, 3rd ed., p. 99, Staudinger diagnoses this form 

 as : " Al. ant. multo pallidior., cinereis, lineis transv. subnull., v. 

 desert, arenos." It comes from the south-east sandy deserts of Russia: 

 Nariin.

 apud marginem exteriorem dilatata fusca ; posticae antice roseae, ocello magno cyaneo- 

 atro. North China. From Mr. Cuming's collection (Walker). Distribution : 

 Yokohama, common (Pryer), Gensan (Leech), Chang- Yang, Kiukiang (Pratt) ; Wei- 

 hai-Wei, July 16th, 1898 (Fletcher). 



This form, first described by Walker from North China, was 

 afterwards redescribed as argus by Menetries. Staudinger (Rom. 

 Mem., vi., p. 236) remarks that " it was discovered by Schrenck and 

 Maack in the southern Amur district ; Christoph bred it at Wladi- 

 wostok, Dorries on the Ussuri, Suifun and Bikin, Graeser at 

 Chabarowka, Blagoweschtschensk and W T ladiwostok. It also occurs 

 in north China, and was described from there as planus, Walk., 

 which name must certainly be referred as synonymous with argus.'' 

 Bacot says that "it is slightly larger, paler in colour, the ocellated spots 

 rather larger than in our British form." Staudinger diagnoses (Cat., p. 

 100) it as: "Prrec. var. pallidior, al. ant. haud cervino-tinctis, al. post, 

 ocello majore, basi non rosaceo." Leech writes (Tram. Ent. Soc. 

 Lond., 1898, p. 278): "The differences between planus ( = argus) 

 and ocellata, indicated by Staudinger, do not hold good in my 

 series from Japan, Corea and northern China, when they are com- 

 pared with European specimens. The Asiatic examples usually
