THE BRITISH NATURALIST. 



[May 



species), of an organ on the under side of the fore wing, which he suggested might be 

 for stridulation ; this organ consisting of a small scar of hyaline membrane situated 

 just below the middle of vein 2, which is much curved : this scar is fringed with long 

 hair, and has running down its middle a row of sharp spines situated on the aborted 

 remains of vein 1, and which is curved up close to vein 2 ; the spines would naturally 

 rub against part of the costa of the hind wing, but no spines or unusual roughening 

 seem to exist on that or on any of the veins on the upper side of hind wing against 

 which they could strike ; below the scar is situated a large shallow fovea or pit in 

 the membrane, slightly developed in dotata and flavata, but much more prominently 

 in the two Japanese species, and, should the organ prove to be for stridulation, would 

 probably act as a sounding-board. Mr. Hampson said that in the Japanese species 

 C.Jixreni of Brem, exceedingly closely allied to flavata, the males have no trace of 

 this organ ; and he hoped that entomologists who have an opportunity of observing 

 dotata in life would make some experiments on living specimens during the ensuing 

 summer ; probably confining males and females together would lead to some results. 

 The President, Prof. E. B. Poulton, Lord Walsingham, and Mr. Hampson took part 

 in the discussion which ensued. The Rev. T. A. Marshall communicated a paper 

 entitled "A Monograph of the British Braconidae, Part V." Mons. Louis Peringuey 

 communicated a paper entitled "Descriptions of new Cicindelidae from Mashona- 

 land." Prof. Poulton gave an account of his recent tour in the United States, and 

 commented on the entomological and other collections contained in the American 

 museums. Lord Walsingham, Mr. Hampson, and the President also made some 

 remarks on the subject. — H. Goss, Hon. Secretary. 



April nth, 1894. — Henry John Elwes, Esq., F.L.S., President, in the chair. Mr. 

 F. W. Jones, of 63, Carlton Hill, St. John's Wood, N.W., and Dr. William Steer 

 Riding, B.A., M.D., of Buckerell, Honiton, Devon, were elected Fellows of the 

 Society. The Hon. Walter Rothschild exhibited male and female specimens of 

 Omithoptera paradisea, Stdgr., from Finisterre Mountains, New Guinea; O. trojana, 

 Stdgr., from Palawan; O. andromaclic, Stdgr., from Kina Balii, Borneo; CEnetus 

 mirabilis, Rothsch., from Cedar Bay, Queensland ; and a few other splendid 

 species from the Upper Amazons. The President, Mr. J. J. Walker, Mr. Osbert 

 Salvin, Lord Walsingham, Colonel Lang, Mr. Champion, and Mr. Hampson made 

 remarks on the geographical distribution of some of the species and the elevation at 

 which they were taken. Mr. H. Goss exhibited for Mr. G. A. J. Rothney, several 

 specimens of a species of Hemiptera (Serinetha augur, Fab.), and of a species of Lepi- 

 doptera (Phauda flammans, Walk.), the latter of which closely resembled and 

 mimicked the former. He said that Mr. Rothney had found both species abundantly 

 on the roots and trunks of trees in Mysore, in November last, in company with Ants 

 (several species of Camponotus and Ci'emastogaster). The Hemiptera appeared to be 

 distasteful to the Ants, as they were never molested by them, and he thought that 

 ■the species of Lepidoptera was undoubtedly protected from attack by its close imita- 

 tion of the Hemipteron. Mr. Goss said he was indebted to Mr. C. J. Gahan for 

 determining the species. A discussion followed on the mimicking species, in which 

 the President, Mr. Waterhouse, Mr. J. J. Walker, Colonel Swinhoe, Mr. Hampson, 

 and others took part. Mr. J. W. Tutt exhibited (1) a typical specimen of Lyccena 

 corydon, captured in July, 1893 ; (2) a hybrid male (L. covydon and L. adonis), taken 

 in cop with a typical female L. adonis, May 20th, 1893 ; (3) a typical male L. adonis, 

 May 20th, 1893 ; (4) a female L. adonis, the pigment failing in one hind wing ; (5) a 

 pale var. of L. covydon, probably to be referred to var. apennina of Zeller, usually 

 taken in Italian mountains, or var. albicans, H.S., taken in Andalusia. Mr. Tutt 

 remarked that, of the first, Staudinger (Cat. p. 12) says " pallidior," of the latter 

 "albicans." He also remarked that the hybrid retains the external features of the
