64 BRITISH LEPIDOPTERA. 



records (E?iL, vi., p. 485) another aberration, also bred at Ipswich, 

 of an uniform olive-green colour, excepting the abdomen, which 

 is tipped with bright pink. In 1871, Bond exhibited another 

 Ipswich specimen in which the central portion of each forewing 

 was perfectly hyaline and free from scales. It is figured and 

 described (E/ii., vi., p. 81, fig.) as follows : " The forewings 

 have a large central area, in which the membrane is without scales, 

 the wing-rays only being furnished with scales, and these 

 ochreous ; the rest of the wing is smoky-brown. In the hind- 

 wings is a similar central area, but not so completely denuded 

 of scales as that in the forewings ; at the apical angle the 

 wings are smoky-brown and partially of the same colour as the 

 forewings, but the scales towards the anal angle and nearer the 

 centre of the wing are dull ochreous. The palpi, crown of the 

 head and collar are dull olive-brown ; the thorax ochreous-brown, 

 tinged with rosy, the abdomen brown, the margins of the segments 

 ochreous, and the tip rosy." There is considerable minor variation 

 in our British examples. In many, the bright ochreous-green 

 assumes a duller tint, and the red shades and areas on the fore- 

 wings are of a dull purplish or violet, and much restricted in area 

 at the centre and towards the base of the forewing, whilst the outer- 

 margin of the hind wings is paler in colour (ab. pallida, n. ab.). In 

 some examples, the outermargin of the hindwing is shaded with a tint 

 approaching the ground-colour of the forewing to such an extent as 

 to restrict the pinkish area to a transverse band just outside the 

 middle of the wing ( = ab. virgata, n. ab.), whilst in others, the 

 outer marginal area of the hindwings is, on the other hand, some- 

 times quite whitish. Some examples, otherwise well coloured, have 

 no red markings at the centre of the forewings, except as a shade 

 on the inner edge of the second oblique line, and, rarely, extreme 

 forms have the forewings uniformly ochreous-green (= ab. unicolor, 

 n. ab.). A greenish-ochreous tinge is occasionally carried over 

 the apical area of the hindwings. On the other hand some 

 examples have all the red markings of the fore- and hindwings 

 brilliantly rosy-red, extending into a large patch towards the base 

 of the forewings, and developed as an unusually broad outer marginal 

 area on the hindwings (=ab. clara, n. ab.). Occasionally the white 

 discal spot of the forewings is absent (= ab, obsoleta, n. ab.). 

 The only described forms of this species are as follows : 



a. var. lewisii, Butl., " Proc. Zool. Sue. Lond.," 1875, P- 2 \~ ( I ^7S) i Kirby,

 Leech, ''Trans. Ent. Soc. Lond.," 1898, p. 282 (18981. — Imago : Very like C. elpenor, 

 but duller above, the rosy streaks on primaries less evident, primaries below 

 with the golden discal patch not extending (except as a tine line below lower radial. 

 Expanse of wings 2 inches 10 lines. Japan. Larva: Very distinct from that of 6'. 

 elpenor, brown or green. The brown larva differs principally in having the lower 

 surface and lateral area of the last seven segments brown, with a defined, umlaie, sinuate 

 internal edge, each sinuosity answering to the convex margin o( its segment ; the 

 two eye-like spots are much smaller, and have pale brownish centres in both forms 

 of the larva ; the horn in the green form is longer but less curved than in the brown 

 form. It feeds on fuchsia and balsam. [Without having seen the excellent figures 

 of the transformations obtained by Mr. Lewis. 1 should not for a moment have 

 thought this species distinct from C. elpenor.] (Butler .
