NOTES ON COLLECTING. 135 
along the body in the attitude of rest usual to this species until they 
were fully expanded. It then suddenly threw them over the body like 
a butterfly, the tips of the forewings just touching each other, the 
hindwings and body were thus freely exposed to the air. After about 
seven minutes it again folded the wings along the body in the usual 
manner. This species emerges in the morning, that is to say my nine 
specimens did so. The cocoon is spun on grass like that of a Zyyaena 
and the moth emerges with its back to the grass. In a small wood 
near the quarry above mentioned Hriocrania subpurpurella and 
Nemophora schwarziella were noted. On the 18th, near Midford 
Pammene rhediella was flying over hawthorn blossom, and on the bank 
of the railway a few cases of Humea casta {?) were taken off old 
sleepers and forwarded to the Rev. C. R. N. Burrows, Near the old 
canal many Lipoptycha saturnana were flying briskly over a patch of. 
tansy in the afternoon sunshine. On a grassy patch just above the 
platform of the little country station of Midford I found two larve of 
Cosmotriche (Odonestis) potatoria, the only ones Ihave seen here. Four 
days later I went to Bannerdown. In the lane Eupithecta coronata 
was seen at rest and Chrysoclista aurifrontella on the wing, while the 
first Hucosma pruniana of the season flew out of the blackthorn. At 
Bannerdown there is a group of fine trees mostly beech and oak. I was 
surprised to see many pupe of Pieris brassice fixed to the tree trunks 
from 7-12 feet up. Two had emerged and those I could touch were 
alive. They were perhaps in rather an exposed position which retarded 
their emergence. The butterfly has been now at least three weeks on 
the wing. There were no Cruciferous plants beneath the trees but 
rubbish had been dumped there, and probably some badly attacked 
cabbages had been thrown down last autumn. On the 24th, at Combe 
Down, I saw a Pyrameis cardui chasing another butterfly. They 
presently settled in front of me, the P. cardui was a ? and the 
other was Pararge megera §. They settled a short time, the P. cardui 
keeping just behind the other. ‘Then the ‘ Wall” flew off with the 
P. carduiin hot pursuit. The game continued for some minutes till I 
lost sight of them. At Bathford Hpiblema tedella was shaken out of 
spruce. They were all very dark. There appears to be a tendency 
towards darkness in the Lepidoptera here if compared with those 
found, say, in Surrey. Some light coloured moths flying gaily over 
a white-thorn at the edge of a wood proved to be gs of Capua 
favillaceana, and I took one ¢@ off the grass below, as well as 
Blabophanes ferruginella. A company of small moths was flying about 
the top of a small hawthcrn, I netted some and was surprised to find 
they were Glyphipteryx fischeriella. I have not previously seen this 
species behaving in this manner. They did not attempt to settle on 
the twigs but continued dancing in the air. The late Mr. MacArthur 
told me that in the Shetlands the g of Hepialus humuli, after 
_ pairing, flew in companies round the tops of the higher rocks. 
Perhaps the little moths above mentioned were enjoying a post 
nuptial dance. On the way back I took Bucculatrix boyerella off a 
nettle leaf near a large elm. On 27th Pammene regiana directed my 
attention to a sycamore trunk by its bright orange dorsal spot. 
Shaking spruce firs at Bathford on the 29th, I obtained four specimens 
of a Blastotere which I believe is glabratella. Their position at rest 
was not quite the same as that of an Argyresthia. They spread out
