imagines of the species. However, as all the butterflies were active 

 throughout the winter, the term hybernating in its true sense would 

 not apply to them. What we now want are some experiments to 

 test the vitality of P. atalanta under circumstances as nearly identical 

 as possible with those the butterfly would have to endure in a 

 state of freedom in the warmer parts of Britain during the winter 

 months. — Ed.] 



SOCIETIES. 



Entomological Society of London. — Wednesday, February 5th, 

 1913.— Mr. G. T. Bethune-Baker, F.L.S., F.Z.S., President, in the 

 chair. — The President announced that he had nominated as Vice- 

 Presidents for the ensuing session the Kev. F. D. Morice, M.A., and 

 Messrs. J. E. Collin and J. H. Durrant. — Mr. A. E. Gibbs exhibited 

 a number of insects, principally Syntomid moths, from British 

 Honduras.— Mr. Donisthorpe, males and workers of Formica fusca 

 var picea, Nyl., from the New Forest, and a female from Belgium, 

 and pointed out that it was standing in the Britsh lists as gagates, 

 Latr. He gave a history of var. picea as British, and exhibited 

 workers and a female of the true F. fusca, subsp. gagates, Latr., 

 from Vienna, and pointed out that gagates has not occurred in 

 Britain. — Mr. A. J. "Richards, who was present as a visitor, several 

 very scarce Coleoptera, chiefly from Hindhead. — Mr. W. A. Lamborn, 

 cocoons of Deilemera antinorii, Oberth., from the Lagos district, 

 together with the moths that emerged from them. — Mr. J. A. de 

 Gaye, F.L.S., who was present as a visitor, five males and eight 

 females of Gonometa subfacia, Walker, which came from Lagos, 

 S. Nigeria. Mr. de Gaye explained how the males were captured 

 while they were trying to get into the breeding-cage in which were 

 two newly-hatched females. Prof. Poulton observed that Dr. Lam- 

 born's previous experiences had made it almost certain that in spite 

 of the great difference in size and appearance these insects were the 

 male and female of the same species, but that Mr. de Gaye's 

 experience had now placed the matter beyond doubt. — Prof. Poulton, 

 a leighi female of Papilio dardanus, Brown, together with one 

 trophonius — two members of a family bred by Mr. G. F. Leigh, from a 

 female parent of the latter form. He also exhibited two further sets 

 of parent and offspring of synepigonic Pseudacrceas of the Eurytus, L., 

 group, bred by Dr. G. D. H. Carpenter on Bugalla, in the Sesse 

 Archipelago. — Mr. B. Harold Smith, thirty-five specimens of Phryxus 

 livomica, taken at light in South Cornwall during the last half of 

 May, 1912. — Mr. A. Bacot, a probable gynandromorph of A. virgu- 

 laria, having the right wings melanic, the left wings of normal grey 

 coloration. — Mr. N. D. Eiley, on behalf of M. Andre Avinoff, a 

 collection of Ehopalocera, made on a journey in the Western Hima- 

 layas. M. Avinoff, who was present as a visitor, gave an account of his 

 expedition. — The following paper was read by Commander Walker: — 

 " Trichogramma, Westw., probably Synonymous with Pentarthron, 

 Eiley (Hymenoptera)." By E. C. L. Perkins, M.A.. D.Sc, F.Z.S.
