1902.] 139 



Mr. F. Merrifield pointed out the difference between experiments upon 

 tropical and European species. In the tropics there are not any very great 

 distinctions of seasons and temperature, whereas in temperate climates the 

 seasons arc clearly marked oil from one another. Professor E. B. Poulton ex- 

 pressed his opinion that by breeding species through, Mr. Marshall had proved 

 that one form gives rise directly to the other ; the pairing of the two forms being a 

 biological test of very considerable value. Colonel Swinhoe, Dr. Jordan, and Dr. F. 

 DuCane Godinan also joined in the discussion. Professor E. B. Poulton read a 

 paper on "Mimicry, illustrated by the Sanger-Sheplierd three-colour process," 

 supplementary to his paper read at the Meeting of the Society on March 5th. —

April 16th, 1902.— The Rev. Canon W. W. Fowlek, D.Sc, M.A., F.L.S., 

 President, in the Chair. 



Mr. James Roland Charnlej, of Howick House, Howick, near Preston, Lanes., 

 and Mr. A. T. Gillanders, of Park Cottage, Alnwick, were elected Fellows of the 

 Society. 



Mr. O. E. Janson exhibited specimens of both sexes of Omithoptera Victoria 

 from Ysabel, Solomon Islands, recently taken by Mr. Albert Meek, and remarked 

 on the variation in the colour and markings in the males. Mr. H. W. Shepheard- 

 Walwyn, variations of Euchelia jacobcece taken by him at Winchester in July, 

 1889. Mr. Willoughby Gardner, Ccelioxys mandibular is, Nyl., from the Cheshire 

 coast, a species new to Britain ; and Osmia xanthome I ana, <J and ? , and Osmia 

 parielina, Curt., J and ? , from North Wales. Mr. A. J. Chitty, a specimen of 

 Aglais urlicai taken at sallow on March 28th, having a large portion of the hind- 

 wings cut off so that when folded they were symmetrical in outline. From their 

 appearance he concluded they had been bitten off by some animal, probably during 

 hibernation. Dr. T. A. Chapman called attention to the remarkable bilateral 

 asymmetry in the male appendages of the Hemarid Sphinx, Cephonodus hylas, Linn. 

 He also exhibited specimens removed from the insect, and also of the several parts, 

 as well as a rough sketch of the clasps and tegumen. Mr. C. P. Pickett, 

 Hybernia leucophaaria taken during March at Chingford, Highgate, and Finchley, 

 including the ordinary mottled, the black and white banded, and six very deep 

 chocolate-coloured forms, one unicolorous. He also showed series of Phigaha 

 pedaria, Anisopteryx cescularia, and Nyssia hispidaria from the North Metro- 

 politan district. Mr. H. J. Turner, on behalf of Mr. W. West, of Greenwich, 

 exhibited specimens £ s and ? s of Stictoeoris ftaveola, Bohm., a species new to 

 the British fauna, found amongst long grass in damp places at Lee, Kidbrook, and 

 Shooter's Hill, and identified by Mr. Jas. Edwards and Dr. Sahlberg. A de- 

 scription of the species by Mr. Edwards is published in the Jan. No. of the E. M. M., 

 2nd ser., vol. xiii, pp. 5-6. He also exhibited several specimens of Typhlocyba candi- 

 dula, Kb., a species first discovered by Mr. West at Lewisham and Blackhcath on 

 Populus alba, and remarked that it was interesting to find two quite new species 

 occurring in the district so well worked by Douglas and others in years past. Dr. 

 D. Sharp, F.R.S., communicated a Paper by Miss Alice L. Erableton, B.Sc, entitled 

 " On the Economic importance of the Parasites of Coccidse." Colonel Charles 

 Swinhoe, M.A., F.L.S., read a Paper entitled " Eastern and Australian Drepanulidse, 

 Epiplemidse, Microniida? and Geometridae in the British Museum Collection." Mr. 

 William F. Kirby, F.L.S., contributed a Paper entitled " Additional Notes on Mr. 

 Distant's Collection of African Locustida?."— H. Rowland-Brown, Hon. Sec.
