218 ; THE ENTOMOLOGIST. 
I took my first specimen of both species on the 7th, and 
my last on the 28th, of August; I found them in about 
the proportion of five of C. Edusa to three of C. Hyale. The 
localities in which I took both species were in Oxsettle 
Bottom, near Lewes, and in a clover field of twenty-five acres 
in extent, at Beddingham, about three miles from the town, 
which field had been once mown, and the second crop 
left for seed. The habit of both species appeared to me to be 
for the males to fly very rapidly and wildly across the 
localities frequented, and rarely, in the case of the clover 
field, passing beyond its limits. The females were generally 
resting or flying languidly from flower to flower; but upon 
seeing the males they usually flew upwards to attract their 
attention ; and I did not find that any of the males discovered 
the females when the latter were at rest. 
During the whole of the period of my observations the two 
species were constantly emerging from the chrysalis, and 
nearly all the specimens taken were in fine condition. The 
males of C. Edusa varied but little in colour; the shade of 
orange in most was precisely the same, and but few were 
slightly lighter. None of the females, although but just out, 
were so brilliant an orange as those in my collection, taken 
near Brighton some years ago; and although I did not 
capture one of the variety Helice, still two of the females 
were scarcely orange in colour, but rather of a dark yellow 
colour; and one had the orange suffused with black, in the 
same manner as a specimen in Mr. Bond’s collection, figured 
in Newman’s ‘ British Butterflies.’ 
All the males of C. Hyale were of a rich yellow colour, the 
tint varying very slightly, but some were not nearly so black 
at the tips of the wings as usual; this remark applies to 
perfectly fresh examples. The females of C. Hyale were in 
some cases nearly white; but I took one specimen of this sex 
quite as yellow as the males usually are; and I am disposed 
to think that the ordinary colouration of the females in 
C. Hyale is the reverse of that which obtains in C, Edusa, the 
lighter variety Helice being rare in the latter species, and 
the darker variety in the former. 
1 find that all the continental specimens I possess of 
C. Hyale—taken by myself in Saxony, Bohemia, Tyrol, and 
Switzerland, and received from Russia—are coloured exactly
