spot pale orange. Specimens sometimes occur wliicli are inter- 
mediate between the ordinary form and the present. It Lears 
some resemblance to (1) C. Pliicomone, female ; (2) C. Hyale, 
female, the light form ; (3) C. Erate var. pallida ; (4) C. 3Iyrmi- 
done var. alha. These, however, may be distinguished as 
follows : — The first has no black border to the hind wings ; in the 
second and third the black border of the fore wings does not touch 
the hind margin internally as completely as in Helice ; in the fourth 
the hind wings are much lighter, the spots on their black border 
are larger and squarer, and those on that of the fore wings more 
numerous and defined. The var. Helice is found most commonly 
in the South of Europe ; but some collectors, in 1877, record having 
taken it in the proportion of one to twenty in this country.

(1841). Small specimens of C. Edusa were confounded with 
C. Clmjsotlieme, which, however, is a perfectly distinct insect, as 
will be gathered from the description in the present work. The 
C. Myrmidone of Westwood and Humphreys is merely a strongly- 
coloured variety of C. Edusa. When the variable character of 
G. Edusa is considered, it is not at all surprising that it should 
have been confounded with species so closely allied, at a period 
when it was difficult to obtain a knowledge of the nature and 
habits of these.

Expands from 2’06 to 2-18 in. The male has the wings of a 
deep orange-colour, speckled over with black scales, and strongly 
shot with rich purple. All the wings have a black border, which is 
about as wide as that of G. Edtisa, and veined with orange. The 
fore wings have a black discoidal spot, and the hind wings a bright 
orange one. The female is somewhat larger than the male, of a
