(i. xvul ) 
Association such list of species in need of protection as shall 
be drawn up and, if necessary, from time to time amended by 
the Committee of the Entomological Society of London 
appointed to that end.”’ 
The draft of alterations and additions to the Society’s Bye- 
laws, recommended for adoption by the Council, in accorc- 
ance with a notice received under the provisions of Chap. XXJ. 
of the Society's Bye-Laws, and signed by the following 
Fellows : Sir George Hampson, Bart., Messrs. R. McLachlan, 
F.R.S., F. Merrifield, W. F. H. Blandford, G. C. Champion, 
Herbert Goss, Martin Jacoby, and J. W. Tutt, was read for 
the first time. 
Mr. McLachlan showed, on behalf of Mr. Gerald Strick- 
land, a magnified photograph of Brachycerus apterus, obtained 
by direct enlargement in the camera, and extremely clear in 
definition and detail. 
Mr. Tutt exhibited some of the silk used by Tephrosia 
bistortata to cover its ova. His attention was first drawn 
to it by Mr. T. Baty, but directly afterwards the slide con- 
taining the silk was received from Dr. Riding, who stated 
that the silk was contained in a pouch at the extremity of the 
abdomen, between the upper part and sides of the vaginal 
sheath and the abdominal walls, being packed in the form of 
dense bundles about 2 mm. long, and resembling in miniature 
locks of wavy flaxen hair. A detailed account of the working 
of the ovipositor and the placing of the silk was given by 
Dr. Riding (Ent. Rece., ix., No. 5). The importance of the 
discovery lay more particularly in the suggestion it afforded, 
that the material with which several Lasiocampids and 
Liparids covered their eggs, which had often been described 
as consisting of scales from the anal segment, might most 
probably prove to be analogous with that described by 
Dr. Riding, and to be secreted in the same way. The 
presence of such glands had hitherto not been suspected in 
the imago. Attention was drawn to the very different ap- 
pearance presented by the material used to cover the eggs in 
such species as Porthesia similis and Leucoma salicis, the 
saliva-like appearance of the egg-covering in the latter species 
being very remarkable.
