 p. 56, pi. xiii. fig. 2. 



40—44 mm. 



S has all the wings pale orange, brightest in 

 the centre, paler and occasionally greenish towards 

 the margins. F.w. with a rather broad black 

 border, nearly the same width throughout : it is 

 crossed by distinct yellow veins ; disc, spot black, 

 slightly reddish in the centre. H.w. dusky at base 

 and light yellow along in. marg. Outer marginal 

 border narrow, but distinct and veined with yellow. 

 Disc, spot orange. $ generally rather larger than 

 S . Black borders of all the wings broader, un- 

 striped, but enclosing a row of large greenish- 

 yellow spots. H.w. greener than in $ , discoidal 

 spot conspicuously orange. U.S. f.w. light orange 

 at base ; greenish along out. marg., parallel to 

 which is a row of black spots ; disc, spot white 

 centred. H.w. greenish-yellow. Disc. spot, silvery, 

 surrounded by a dull red ring and having a smaller 

 spot placed above it. At the base is a dull red 

 mark and another on the costa. An indistinct row 

 of spots of the same colour runs parallel to the 

 out. marg. Fringes, head, antennae, and legs red. 

 Thorax and abdomen black above, light yellow 

 beneath.

a. ab. $ alba. There is a white form of the 

 female analogous to C. eclusa ab. lielice. Miss 

 Fountainehas taken a specimen of this, I believe, at 

 Modling, near Vienna. 



The Nearctic form O. heewaydin Edw., with its 

 variety ariadne. Edw., is very closely allied to 

 C. chrysotheme. In all probability they are co- 

 specific with it. They inhabit the Southern and 

 Pacific States of Nqrth America.

20—28 mm. 



Varies both in colour and| markings, g has the 

 borders of the wings narrow and veined with 

 lighter colour as in C. chrysotheme, but on f.w. it is 

 not of such uniform width, but is wider at its 

 costal end. F.w. sometimes with a black disc, 

 spot, and sometimes without. Ground colour 

 greenish-yellow, but often of a pale ochre. H.w. 

 with the marginal band reaching only about half 

 the distance of the out. marg. ; disc, spot very 

 faint. $ has the marg. borders less sharp inter- 

 nally than in $: they arejnot veined, but have five 

 or six ill-defined light-yellowish spots of the same 

 colour as the wings, which are darker than in $ 

 and of an ochre-yellow. As in the $ the black 

 rase, spot is sometimes quite obsolete ; that of the 



h.w. is more defined than in $ . Fringes greenish, 

 white or ochre in both sexes. Antennae greyish- 

 yellow in (?, in $ showing a slight trace of red. 

 U.s. f.w. light yellow with a greenish-grey border.

Disc, spot, when present, white centred. H.w.

3 wings pale yellow, with black marginal 

 borders, which are sometimes as broad as those in 

 C. edusa. In the typical form of the species they 

 are not veined, but are finely powdered with 

 yellow ; the basal shading is inappreciable. Disc, 

 spot f.w. varies in size in different specimens, but 

 is always very small. That of the h.w. only just 

 visible, being nearly of the same colour as the 

 central area of the wing. U.s. ground colour of 

 wings deeper yellow than above. Out. margin of 

 f.w. and h.w. shaded with dusty greyish green, 

 disc, spot h.w. pearly white. $ marked as in 

 c? , but the marginal borders are less sharply de- 

 fined at their inner edge. In some specimens 

 there are slight traces of light spots. Ground 

 colour of all the wings greenish white. Marginal 

 fringes, head, and antennae red in both sexes.
