Entomoiogical Society of Londox : Octoler Ith, 1891. — Dr. David Shaep, 

 F.R.S., Vice-President, in the Chair. 



The Chairman referred to the death, on the 14.th September last, of Mr. E. W. 

 Janson, who had been a Member of the Society since 1813, and who had formerly 

 filled the offices of Secretary and Librarian respectively. 



The Rev. Dr. Walker exhibited a long series of several species of Erebia, and 

 oi,A)\gynnis Pales, which he had recently captured near Eoldal, in Norway. 



Mr. W. L. Distant exhibited specimens of Danais CJiri/sippiix, with its two 

 varietal forms, Alcippus, Cram., and Dorippus, Klug, all which he found together 

 in the Pretoria district of the Transvaal. Mr. Jenner Weir, Colonel Swinhoe, and 

 ]\Ir. Distant took part in the discussion which ensued as to these forms and their 

 distribution. 



The Rev. W. F. Johnson sent for exhibition specimens of Vella currens from 

 stagnant water near Armagh ; also a specimen of Nobis limhatus, killed whilst 

 holding on to its prey, a very hard species of Iclmeumon. Mr. Saunders thought 

 that, from the nature of the Ichneumon, the only chance the Nabis had of reaching 

 its internal juices would be through the anal opening, as recorded by Mr. E. A. 

 Butler in a similar case, in the Ent. Mo. Mag., October, 1891. 



ilr. F. P. Pascoe exhibited two British species of Diptera, unnamed. He said 

 they had been submitted to Mr. R. H. Meade, but were unknown to him, and are 

 probably new to the British list. 



Mr. R. Adkin exhibited two specimens of a supposed new species of Tortrix 

 {Tortrix JDonelana, Carpenter), bred from larvse found on pine trees at Tuam. Mr. 

 C. G. Barrett said he examined the specimens with great care, but he did not con- 

 sider that they belonged to a new species. He was unable to distinguish them from 

 Tortrix viburnana. 



Mons. A. Wailly exhibited preserved larvaj, in various stages, of Citheronia 

 regalis, which he had bred from ova received from Iowa, United States. He said 

 that the inhabitants called this larva the Hickory Horned Devil, and that the speci- 

 mens exhibited were the first that had been bred in this country. Mons. Wailly 

 further exhibited three female specimens of Anthercea yama-mai bred from cocoons 

 received from Japan ; also a nest of cocoons of Bombyx Radania, received from the 

 west coast of Madagascar. Prof. J. B. Smith, of the United States, and Col. 

 Swinhoe took part in a discussion on the habits of the larva; of Citheronia regalis, 

 and as to the period at which they dropped their spines prior to pupating. 



Dr. Sharp exhibited several specimens of a weevil, Ectopsis ferriigalis, the ends 

 of the elytra of which bore a close resemblance to the section of a twig cut with a 

 sharp knife. He said he had received the specimens from Mr. G-. V. Hudson, of 

 Wellington, New Zealand, who stated that they were found resting in large numbers 

 on dead trunks and branches of Panax arborea in the forests. 



Mr. Gr. C. Champion stated that the species of Forficididce, captured by ]\Ir. J. 

 J. Walker, R.N., in Tasmania, and exhibited by himself at the meeting of the 

 Society in April last, was, he believed, referable to Anisolabis tasmanica, Bormans, 

 described in the " Comptes Rendus " of the Ent. Soc. Belgique, 1880, p. Ixviii. 



The Rev. A. E. Eaton made some remarks on the synonymy of the Psychodidce, 

 and stated tliat since August, 1890, he had identified all of the British species in 

 Mr. Yerrall's list, except Sycorax silacea. 



Mr. Gervase F. Mathew, R.N., communicated a paper, entitled, " The effect of 

 change of climate upon the emergence of certain species of Le}>idoptera." A dis- 

 cussion followed, in which Mr. Stainton, Mr. Barrett, Dr. Sharp, and Mr. McLachlan 

 took part. — H. Goss, I£o7i. Secretary.
