218 THE ENTOMOLOGIST. 



I took ray 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 suff'used 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
