NOTES ON THE SEASON OF 1920 IN WEST SUSSEX. 131 
the Downs in numbers. Ll. cardui, freshly emerged, and Colias 
edusa were seen for the first time. On August 5th Aricia medon 
second brood appeared. G. rhamni was noticed on 7th. On 
August 9th A. cydippe, in battered condition, was taken, and on 
August 18th D. paphia in fair condition still, with P. egerides, 
third brood, newly emerged. On August 16th between twenty 
and thirty C. edusa were seen and five taken. On August 27th 
A. bellargus was freshly out. September 1st C. edusa still fairly 
plentiful. September 9th A. aglaia seen and taken in fair con- 
dition although a very late date. September 14th P. egerides, 
fourth brood, taken. Another seen on September 23rd. October 
set in wet and windy, but the weather improved after the first 
week. P. atalanta was particularly abundant on the flowers of 
scabious. C. edusa could be seen at any time by visiting the 
locality it frequented, and from which it did not appear to stray. 
C. pamphilus and P. rape were seen for the last time on 
October 7th, and H. jurtina on October 14th. A belated P. 
icarus was taken on October 18th. On October 23rd a large 
dragon-fly, A’schna cyanea 3, was taken. P. atalanta had not 
been seen since October 11th, and those seen were much worn 
and damaged, but on October 24th, a beautifully fine day after a 
fogsy morning, two perfectly freshly emerged specimens, with all 
the bloom upon them, were taken upon the flowers of garden 
scabious. ‘here can be no doubt as to their recent emergence, 
as one emitted a drop of the red fluid peculiar to freshly emerged 
specimens, in the box in which it was confined. On October 
25th P. atalanta and P. cardui were seen and C. edusa taken, 
also a dragon-fly, Sympetrum striolatum. On 26th, 27th and 28th 
A. urtice was seen in the garden. On October 29th C. edusa 
was seen and a male P. icarus, in passable condition, taken. 
On October 30th P. atalanta was seen for the last time. On 
October 81st the weather changed to dull and cold and hopes of 
taking a November edusa were abandoned. ‘I'wenty specimens 
of C. edusa were taken in all—all males with one exception. 
No striking aberrations were met with. Of thirty-two C. 
phleas taken, seven were referable to ab. c@ruleopunctata. Of 
twelve V. io, three were ab. cyanosticta. One very dwarf P. napi 
was taken, measuring only 32 mm. across the wings. Of a long 
series of EH. cardamines the largest female measured 46 mm., 
and the smallest male 33 mm. 
Wednesday, November 17th, was a beautifully fine, sunny 
day, without wind after a hard frost. P. atalanta was seen flying 
in the sunshine at 11.30 and G. rhamni two hours later.
