Note on emergence of Pachys betularia.— Mr. A. Bacot made 
an observation concerning the hatching period of Pachys betularia. 
He found that in nature the moth emerged in the afternoon, but in 
captivity generally between midnight and early morning. He 
attributed this to the different variations of temperature, the house 
temperature being usually highest in the evening owing to the gas, 
Ac., while in the air the maximum usually occurred at about 8 p.m. 
Pink rilies of the valley. —Mr. J. Riches, a bunch of pink lilies 
of the valley. He said they were uncommon, hut not much sought 
after, as the white form was undoubtedly the more beautiful flower. 
June 7th, 1904.— -Brood of Ematurga atomaria.- —Mr. A. Bacot, 
a series of Ematnnya atomaria bred from ova obtained from a very pale 
specimen taken near Leith Hill. The brood, however, showed 
practically no variation. 
Pachys betularia var. doubledayaria. —Mr. W. Bloomfield, a 
specimen of Pachys betularia var. doubledayaria, bred from a pupa dug 
at Balls Pond. 
Boring’s in an ash stem. —Rev. C. R. N. Burrows, an ash stem 
bored by larvae, which he suggested might be Cirrhoedia xerampelina. 
Mr. A. W. Mera, however, stated that it was too late for this species, 
as a friend of his had received full fed larva! of this insect three weeks 
previously. Mr. L. B. Prout thought the larva was possibly Prays 
ciirticellus. 
Dark Pararge egeria. —Mr. S. Dale, a specially dark specimen of 
Para rye eyeria . 
Larvae of Ithysia lapponaria. —Mr. A. W. Mera, larvae of Ithysia 
lapponaria in the last stadium, bred from ova received from a 
correspondent, and laid by a British specimen. Mr. Mera mentioned 
that whilst this larva would eat knotgrass and sallow it much preferred 
birch. 
Aberration of Mimas tili^e. —Mr. C. P. Pickett, specimens of 
Mimas tibiae bred during 1904, including a very reddish coloured 
female, and a male with the more green colouration usually found in 
the female. The two specimens had been paired and ova obtained. 
Notes on Lars sambucaria.— Mr. Pickett, pupae of Lars sambu- 
caria, which had used an empty pupa case of Vanessa atalanta in the 
construction of their cocoons. 
Collecting notes. —Mr. Pickett reported that during a recent 
visit to Clandon he had found Nemeobius lucina very plentiful; 
Collophrys rubi was worn, and Polyommatns icarus and Polyommatus 
agestis just coming out. He also saw' one Hemaris fuciformis and a 
few Brenthis euphrosyne. Mr. L. B. Prout reported finding Coremia 
desiynata commonly in the neighbourhood of Connaught Water, 
Epping Forest. No larvae were found either of Philoseme cetulata or 
Philoseme transversata, these having apparently pupated. Larva; of 
Tripliosa dubitata were well forward. 
Delegate to the S.E. Union of Scientific Societies. — Mr. V. 
Eric Shaw having written to the effect that he wished to be released 
from his appointment as the Society’s delegate to the conference of 
the S.L. Union of Scientific Societies, Rev. C. R. N. Burrows pro¬ 
posed, and Mr. A. W. Mera seconded, that Mr. J. W. Tutt be 
requested to represent the Society. The proposal was carried 
unanimously.
