to look for it in the nests of umhratus nndei- deeply embedded, heavy stones. 

 Dr. T. A. Chapman, a teratological example of Pterostoma palpina, one of a 

 number of similar specimens bred by Mr. L. W. Newman from one brood of 

 larvte, and which may be called as a varietal (or abeiTational ?) name, var. 

 brevipennis, and for comparison a specimen of Lihythea celtis with a shortened 

 wing. He also exhibited, on behalf of Rev. C. R. N. Buri-ows, a specimen of 

 malformation of the male appendages in Acronycta tridcns. Mr. H. M. 

 Edelsten, an example of Leucania l-album, bred by him. Mr. R. South, an 

 exceedingly interesting and rather variable series of Luperina gueneei, Double- 

 day, sent him by Mr. W. Yates, of St Anne's-on-Sea, who obtained them, 

 chiefly this year, on the Lancashire Coast ; also three of six specimens of Oria 

 (Synia) viusculosa, taken in the Salisbury district, in Atigtist, 1909, by Mr. H. 

 Haynes, who captured others in August of the present year. Mr. F. C. Oldaker, 

 a case containing various aberrant forms of Lcpidoptera, including a very dark 

 form of Argynnis aglaia, taken in Switzerland; (h) examples of Polygonia 

 c-album bred from ova, including one specimen, a ? , of a very pale form ; 

 (c) a series of Noclua ditrapeziuvi, including a form in which the ground-colour 

 of the fore-wings is almost uniform dark reddish-brown, the usual black 

 markings being only slightly darker than the rest of the wing, and very faintly 

 discernible : and {d) a series of Ejnone adve^iaria, Ijred from ova at Haslemere, 

 1907 ; one of a remarkable form very much smaller than usual, and of a 

 iiniform dvill lirown colour, with white fringes, biit no markings on the wings. 

 Mr. A. H. Jones, a series of Melitxa dictynna, var. vcrnetcnsis, Oberth., taken by 

 him this year at Vernet-les-Bains, Pyrenres-Orientales, and said that in his 

 opinion the so-called variety was probably a distinct species, having regard to 

 its general appearance, and the surroundings in which it. is taken. With it he 

 also shoAved examples of M. dictynna type, and M. athalia for comparison. Dr. 

 Malcolm Burr, D.Sc, M.A., communicated a paper entitled " A Revision of the 

 Labiidae, a Family of Dermaptera." The Rev. F. D. Morice read a paper 

 entitled " Hymenoptera Aculeata collected in Algeria : The Sphcgidx," being 

 Part V of the work commenced by the late Edward Saunders, F.R.S., F.E.S., in 

 the Trans. Ent. Soc, 1904, p. 515. Professor E. B. Poulton, D.Sc, M.A., F.R.S., 

 communicated a paper entitled " Experiments with the larva and pupa of 

 Uropteryx sambucaria in connection with their Coloiu- Surroundings," by 

 Elizabeth Bridges. The President, at the close of the discussion \\hieh 

 followed, proposed a special vote of thanks to Miss Bridges, who was present, 

 which was cari-ied unanimovisly. — H. Rowland Brov^n, Uon. Secretary.
