and little known species. He also exhibited the common Ixodes reduviua for com- 

 parison, together with photographs of /. fimbriatus. Dr. Chapman, a living bred 

 specimen of Endromis versicolor, and some pupae, in the larva-cases of Thyridopteryx 

 ephemerarformis. Mr. Edwards, very fine examples of Ornithoptera Lydeus, and O. 

 Socrates from the Malays, with Par nassius imp erato rand P. Horsleyanux from Thibet. 

 Mr. Turner, a long bred series of Macroglossa stellatarum, from larvae obtained at 

 Bromley, Kent, and contributed notes on breeding and habits of the larvae. Mr. 

 Lucas, a very large number of lantern slides to illustrate his remarks on " Entomo- 

 logical localities." They were chiefly of well-known spots in the New Forest. Mr. 

 West, of S treat ham, showed a few slides taken from several localities near London.

 W. W. Fowler, M.A., F.L.S., President, in the Chair. 



Dr. P.. Douglas Macdonald, M.D., of Malsette, Rhodesia, S. Africa ; and Mr.

Mr. L. Pi. Pro nt exhibited on behalf of Mr. J. P. Mutch, of Hornsey Road, 

 London, N., aberrations of Vanessa (Eugonia) polychlorox, L., a $ bred by Mr. H. 

 Baker from pupa from Stowmarket, Suffolk ; a Chrysophanus Phlceas, L. (captured 

 in the Isle of Wight, August, 1901) ; Agrotis pitta, Hb., a perfectly-halved 

 gynandromorphous example, the right side <J , the left side ?, taken in August, 

 1901, in the Isle of Wight ; and Noctua sobrina, Gn., an aberrant specimen with 

 white antennae and a somewhat hoary appearance on the fore-wings, taken in East 

 Aberdeenshire, August, 1900. Mr. A. Bacot, a series of Malacosoma castrensis 

 and a series of M. neustria for comparison with a hybrid brood, resulting from a 

 pairing between a male neustria and a female castrensis, only a portion of the batch of 

 from 200 to 300 ova that the female had hatched. The last of the females that even- 

 tually emerged was three weeks ahead of the first male, and most unfortunately before 

 any males of either of the parent species, so that the fertility of the hybrid females 

 could not be tested. Their bodies apparently contain few, if any, ova. Mr. Bacot said 

 he had every reason to believe, however, that he obtained pairings bet ween the hybrid 

 males, and females of castrensis, in addition to fresh pairings between males of neustria 

 and females of castrensis, and therefore had hopes of continuing the experiment next 

 summer. Mr. J. W.Tutt remarked that this was the first time any exhibition of experi- 

 ments of the kind had been made before the Society by British investigators, 

 although Mr. Merrifield had shown a number of crosses bred by Herr Standfuss. 

 In this case the colouring of the 9 hybrids, departing from the usual colour of the 

 $ s of the parent species, appeared to approach more closely in tint the ?s of the 

 closely allied Alpine species, Malacosoma alpicola, and it would be interesting to 

 discover whether this peculiarity of colour in the hybrid ? s really marked a ten- 

 dency ro revert to a more primitive V type of coloration, such for example as that 

 exhibited by ? M. alpicola. The sexes, as exhibited, were very clearly distinguish- 

 able, and there was not much tendency to gynandromorphism, though of sixty or 

 seventy specimens almost every 9 showed some signs of $ coloration. A 

 discussion of the relative preponderance of the sexes in gynandromorphous
