comments on the occurrence of Limeniti. s sibylla in the Suffolk woods. 
He considered that the species only frequented those woods with broad 
shady glades, where light and shade were very marked, in order that 
its own colours would harmonise. 
^ May 17th, 1904.— Delegate for S.E. Union of Scientific 
Societies. —Mr. V. Eric Shaw was elected to represent the Society at 
the S.E. Union of Scientific Societies’ conference, to be held at 
Maidstone. 
Spring lepidoptera. —Mr. C. P. Pickett, Lycia hirtaria, from his 
garden at Leyton, and some fresh bred Synopsia abruptaria; also some 
Mimas tihae. The S. abruptaria were rather darker than the normal, 
but were far removed from the melanic and deep chocolate forms 
obtained at Holloway, &c. 
Highgate lepidoptera. —Mr. R. G. Benton, Bombycia ocularis and 
Plusia moneta, from the Highgate woods. Mr. R. G. Todd said that 
the former w'as not very rare there. He had himself taken four 
specimens. 
Ova of Eupithecia nanata.— Mr. V. Erie Shaw, ova of Eupithecia 
nanata. He suggested that there might be a second brood of the ' 
species. Mr. L. B. Prout said he thought there was only one extended 
brood. At Forres he had taken the imago in August, and these were 
certainly not of a second brood. 
Dwarf Catocalas.— Dr. -T. S. Sequeira, specimens of Catocala 
promissa and Catocala sponsa, some of which were remarkably under¬ 
sized. 
Note on Eupithecia nanata.— Dr. T. A. Chapman remarked on 
the Eupithecia nanata exhibited, and said that it was possible there 
might be two broods in the south, but it was certain there was only 
one in Scotland. 
Graphiphora gracilis.— Mr. A. W. Mera, (jraphiphova i/racilis, 
showing the white, red, and intermediate yellowish forms. The last 
were from Rannoch and exhibited some beautiful phases. 
Libythea celtis larwe, etc.— Dr. T. A Chapman, larvie of 
Libythea celtis and Melitaea didyma, the latter were stated to rest near 
the top of a flower-stem of plantain, and were wonderfully protected 
by their great likeness to flowers of the plant. 
Retarded emergences.— Mr. L. B. Prout said it would be most 
interesting if members would record any instances of retarded emer¬ 
gences when the moths were produced this year. It was likely that 
a great number of specimens would hatch this year that had failed to 
come out during 1908. Mr. A. W. Mera said he considered that many 
species had to appear at a certain time and if they failed they died. 
Mr. Prout vuis of opinion that certain atmospherical conditions were 
necessary at a certain stage of the pupa’s existence for development, 
but if that development within the pupa failed the pupa might very 
often lie over till the same period the following year. But once 
development had taken place the imago had to emerge or die. Mr. A. 
Bacot referred to Dr. Chapman’s experiments with the Tieniocampid 
species, when it was found that development took place in the autumn 
and the motbs were ready to emerge with the first warm days of spring. 
If they failed to hatch they could not go through a second winter and 
therefore died.
