VARIATION OF AGLAIS UKTIC.E. O 



markings that constitute the " tout ensemble " of the insect, and to 

 each of these I proceeded to assign a Latin name. After all, the 

 markings (liable to vary) are but few and simple. Each of the three 

 large black blotches along the costa of the forewings I have termed 

 a "macula"; the large one in the centre of the inner margin is a 

 " nota " ; and to the two smaller ones in the central area the name of 

 " puncta " is appropriately given. The outer margin is naturally 

 termed the " margo," and the blue lunulated spots within it "guttfe." 

 These complete the markings of the forewings. The outer margin of 

 the hindwmgs also has a black edging which contains blue markings 

 similar to the "guttfe," but which, for the sake of distinction, are here 

 termed " lunulae." The only other variable portion of the hindwings 

 is the central, red, transverse belt, which at once suggests its parent- 

 word " balteus." If those of your readers who have followed me so 

 far, and wish to understand the accompanying table, will get these Latin 

 names well into their minds, I think they will find but very few 

 difficulties in their way; but, before coming to the "scheme," I should 

 perhaps say that in it " infra " refers to the upper surface of the hind- 

 wings, and "subtus" to the underside of the insect; whereas "dorsum" 

 represents the inner margin, and "tornus" the point of junction 

 between this and the outer margin. 



In the first place I append an alphabetical list, with full references 

 and descriptions of the 21 (really 20) varieties already described by 

 various authors, only premising that cflsc/i»r/?-t?«s/s = ;-urt««, and, having 

 priority, causes ri::ana to disappear.

 infuscatis)=like icJmusoides (of Selys), but with hindwings entirely fuscous. 



caendapicata, Eaynor, "Ent. Eec," xviii., 298, "with pale chalky-blue apex 

 to forewings." 



canchndrensis, Kollar, "Hiigel's Kaschmir.," vol. iv., p. 442 (1844), t. 9, figs. 3, 4; 

 Nicev., ''Butts. Ind.,'^ ii., p. 233 (major, obscurior, al. ant. sine mac. caerul.)=a 

 large dusky form, without blue spots on forewings. 



chitiensis, Leech, "Butts. China," p. 258, t. 25, fig. 1. \ ar. thihetmia, kuBt., 

 " Nat.," 1898, p. 201 (major, saturatius fulva, al. margine toto nigro, caeruleo- 

 maculata) = deeper tawny, with entirely black margins, spotted with blue. 



con/unctfl, Neub., " Soc. Ent.," xix., 170 (1905). — Agrees in a general way with ab. 

 atrebatensis, B., but all three costal blotches are united, forming a continuous 

 black stripe in which not at atom of the ground colour remains. Bred by 

 Dr. Dannenberg in a low temperature. Locality not stated. 



C07inexa, Butler, "Proc. Zool. Soc. Lond.," 1881, p. 851 ; Leech, "Butts. China," 

 p. 258 (al. ant. fascia media nigra) = forewings with central black fascia. Tutt, 

 Brit. Butts., 1896, p. 336, says, "A Japanese local form, with the inner 

 marginal spot united with the costal, forming a central transverse band. 

 Almost identical vf ith jiolaris, except for its brighter colour." 



dannenhergi, Neub., " Soc. Ent.," xix., p. 170. — Inclining towards ab. ichnusoides, 

 Sel. The blue marginal spots of both forewings and hindwings replaced by 

 spots of a decided straw-yellow colour, those of the hindwings being produced 

 as wedges towards the margin, and with stronger black dusting between them. 

 Underside unicolorous black, the yellow spots forming a broad yellow marginal 

 band. Bred by Dr. Dannenberg. Apparently the result of a temperature 

 experiment. 



discolor, (Hein.), Kiihl, "Gr.-Schm.," i., p, 778. " Groundcolour dark ochreous- 

 yellow ; the blue marginal spots present on both wings ; border black. Fore- 

 wing with three black costal spots, separated by yellowish spots ; a white spot 

 beyond the outer black one ; a large black spot not far from the inner margin, 

 without a yellowish one beyond it ; two black spots in the middle of the 

 wing. Hindwing broadly black at the base ; a ixiuddy ochreous-yellow band
