NOTES ON COLLECTING. 167 
The collection of Heliconius now at the Hill Museum, is perhaps 
unrivalled. : 
The Museum has in progress papers on the Lepidoptera of Hainan, 
of the Schouten Islands, of Dutch New Guinea, Misol, Aru, Key, Obi, 
and Sula Islands, and of Central Ceram. 
Mr. T. A. Barnes, F.Z.S., has recently returned from an expedi- 
tion of twelve months’ duration through little-known parts of Central 
Africa, undertaken on behalf of Mr. Joicey. A very fine collection of 
Lepidoptera was obtained, and Mr. Barnes has recorded many valuable 
biological observations. A report on this collection is in progress. 
Mr. Barnes was accompanied by his wife on the trip of over 8000 
miles. Cinematograph films were taken en route, and some of im- 
portant scientific interest. 
Consignments of Lepidoptera are shortly expected from Dutch 
New Guinea, where Mr. Joicey’s collectors, the three brothers Pratt, 
are at work in the mountainous interior of an area entomologically 
unexplored. 
It is proposed to publish a catalogue of all types of Lepidoptera 
existing in the Hill Museum, as these are now very numerous, and 
' concern many different authors. 
Students desirous of comparing specimens and types are invited to 
write to The Curator, The Hill Museum, Witley, Surrey. 
ARGYNNIS CyDIPPE (aDIPPE) on Ruiaare Hrnx.—I took a fine male 
specimen of A. cydippe last week on Reigate Hill. J] hear that this 
species has not been seen at Reigate for many years.— Henry Speyer, 
Highbury, Reigate, July 21st, 1920. 
APATURA IRIS IN FEBRUARY.—Some time ago when in Paris I was 
informed that a specimen of A. iris was caught in February last by a 
Mr. Bishop some few miles from Paris, surely a most unusnal 
occurrence at that time of year.—-Gro. Tatpor, The Hill Museum, 
Witley, Surrey. 
Epurava picknarpi, Dry., a Britis Insecr.—According to Mons. 
P. de Peyerimhoff, the lance mentioned by me (antea, p. 158) is Hf. 
bickhardi, Dev. I hope to write a note on ane insect shortly.— 
Horace Donistvores. 
ZYGAENA TRIFOLU.—On June 6th, 1920, when breaking fresh 
ground in a favourite collecting wood that I visit, I discovered. 
two adjacent meadows at the edge of the wood that have been ' 
allowed to become rough, and as there were plenty of flowers in bloom 
I walked them over, putting up a number of Z. trifoliitmy luck was 
in for I had struck a colony much given to aberration, quite 66 % 
being abnormal—from ab. orobi to ab. minotdes, as illustrated in 
South’s Moths of the British Isles; the latter form was the rarest, but I 
secured a few quite good. On June 9th I saw the first 7. filipendulae 
in the same spot; from. that day onwards both were flying together, 
but although I searched carefully, I failed to find any cross pairings. 
Since that time until August 22nd Z, filipendulae hag been flying 
there freely, but none that I have netted of this species show any signs
