Smerinthus populi, ab. —Mr. G. Brooks exhibited a specimen, 
dark brown in colour, taken at Barnet, 1910. 
Noctua augur var. omega (Esper).— Mr. V. E. Sbaw, a specimen 
taken at sugar, Finchley, June 28th, 1910. This variety is referred 
to by Tutt in his British Noctuae and their Varieties as a very rare 
form. 
Sesia crabroniformis. —Mr. L. W. Newman stated that when 
collecting osier stumps some were found to contain not only full-fed 
larvae, but also many young larvae. The stumps were kept on the 
concrete floor of a glass-house, and the young larvae migrated from 
the small stems to the larger stumps. 
Pupation of Sesia culiciformis. —Mr. L. W. Newman drew 
attention to the fact that the larva of this insect pupates head down¬ 
wards in year old stems of the birch, while larvae in the stumps of 
course pupate head upwards. 
February 21st, 1911.—Dr. T. A. Chapman, photographs of $ 
appendages of Scoparia, also various specimens of the genus to 
illustrate his remarks on same. 
Dasypolia templi.— Mr. F. B. Cross, a series bred from pupae 
received from Unst, 1910. 
Sesia crabroniformis.— Mr. L. W. Newman, stems showing 
borings and cappings made by S. crabroniformis, some in living and 
some in dead wood, also stems containing larvae of the musk beetle, 
which he said feed side by side with S. crabroniformis, and display 
similar habits. 
Paper. —Dr. T. A. Chapman read a paper entitled “ A note on 
Scoparia,” showing on an examination of the male appendages that 
S. ambigualh and S. atomalis are, as is usually now accepted, one 
species ; that S. basistrigalis is a very distinct species, as also is S. 
ulmella from every other British species, but that it is closely related 
to, possibly a geographical race, of S. manifestella. It also appeared 
that not only English S. ingratella, but also the continental form 
bearing that name, is a variety (or at times an ab.) of S. dubitalis. 
The British species divide into two sections, “ Moss-feeders ” and 
“ Root-feeders,” with S. pallida and S. crataeyella as not quite typical 
of either section. These divisions were clearly recognised by Guenee 
in 1854, but have since been treated with neglect. (The full data on 
which these conclusions are founded are given in a paper read 
March 15th, 1911, at Ent. Soc. of London, by Dr. Chapman.) 
March 7th, 1911.— Exhibition of Cosmiid;e.— Mr. H. M. Edelsten, 
specimens from Epping Forest and Enfield. Mr. A. W. Mera, C. 
trapezina, pyralina, diffinis, and affnis from various localities. Mr. B. 
S. Williams, C. trapezina var. nigra, Tutt, from Finchley, July, 1910. 
Mr. P. H. Tautz, fine series of C. trapezina, pyralina, diffinis, and 
affnis from Pinner, Middlesex. 
Gonoptera libatrix. —Mr. J. Riches exhibited several specimens 
he had found hybernating in a cellar in February, 1911, in a Norfolk 
village.
