320 THE ENTOMOLOGIST. 
Orrhodia erythrocephala, ‘captured by J. H. A. Jenner, Lewes,” 
brought £2.5s. the lot; and four specimens of Xylina zinckenit 
from 18s. to £1 4s. each. Ten specimens of Cleora viduaria put up 
singly realized from 10s. to £1 10s. each, with an average price of 
just over 16s. 6d., and three fine examples of Boletobia fuliginaria 
captured by the late Mr. J. A. Clark, two in Lower East Smithfield, 
and one in St. Katherine’s Docks, just £2 2s. each after a keen com- 
petition.—R. A. 
THe Barker Couiuection. — Yet another collection of British 
Lepidoptera, but of smaller size, has come under the hammer, that 
formed by the late Mr. H. W. Barker being disposed of at Stevens’s 
Auction Rooms on November 16th. There were few really interesting 
lots, but among the more noteworthy a fine Lycena adonis female, 
with splashes of male colour in left fore wing, brought £3 15s.; a 
male L. corydon, under side very near var. obsoleta, with a nice blue 
shot female, £1 the pair; a fine male Nemeophila russula, with hind 
wing much suffused with black, and another with quite clear hind 
wings, £2 15s. the two; a couple of confluent-spotted Arctia villica, 
with two fairly darkly-marked A. catia, £1 2s. the lot; and a fine 
series of thirteen Cymatophora fluctuosa £1 12s. 6d.—R. A. 
WantTED.—For breeding experiments in Heredity and Sex-deter- 
mination, pup of S. mendica and its (Irish) var. rustica.—L. Don- 
cASTER; Zoological Laboratory, University, Birmingham. 
CAPTURES AND FIELD REPORTS. 
ABUNDANCE OF PIERIS BRASSICH.— Following on Mr. Joseph 
Anderson’s note on this species (antea, p. 282), it may be of interest 
to mention that Prerzs brassice began to be seen in goodly numbers 
about the gardens in Eastbourne and on the railway-banks on the way 
to London about Aug. 12th, and from that time it became more and 
more common until about the 22nd of that month, whenit was met with 
in unusual abundance not only in the town, but on any sheltered parts 
of the downs where there were any flowers to attract it. It then 
gradually diminished in numbers until, by the beginning of October, 
only an occasional specimen was to be seen. I did not observe any 
concerted movement on the part of the butterflies, nor was it a case 
of the sudden appearance of large numbers as has been observed 
under the influence of migration, but just a gradually increasing 
number of individuals quite compatible with the natural development 
of unusually large broods. By the end of September full-fed larve 
also were frequently seen wandering in search of suitable places for 
pupation, and not a few found their way in at the windows of the 
house where I was staying, although there was no adjacent cabbage- 
garden, and spun up on the walls and ceilings of the rooms; and 
little bunches of yellow ichneumon cocoons, as well as healthy pupe, 
were not infrequently seen under the copings of walls in the neigh- 
bourhood.—Rosertr Apkin; Lewisham, November, 1909.
