42 THE ENTOMOLOGIST. 



SOCIETIES. 



Entomological Society of London. — December 7th, 1898. — Mr. E. 

 Trimen, F.R.S., President, in the chair. Monsieur Leon Candeze, of 

 64, Rue de l'Ouest, Liege; Mr. C. L. B. Stares, M.R.C.S., L.R.G.P., 

 of the Infirmary, Wandsworth, S.W. ; Mr. A. Russell, of the Limes, 

 Southend, Catford ; and Mr. C. B. Holman Hunt, of Meddecombra, 

 Watagoda, Ceylon, were elected Fellows of the Society. Mr. 

 McLachlan exhibited a series of specimens of the neuropterous genus 

 Tetracanthagyna, De Selys, including a pair of a new species from 

 Borneo, which was the largest known of all recent dragonflies, though 

 it was slightly exceeded in wing-area by the much more slender 

 Megaloprepus ccerulatus, a common Central- American species. Mr. 

 A. H. Jones showed about sixty species of Lepidoptera, taken round 

 electric lights at Zermatt, in August. Among the more interesting 

 were Craterouyx taraxaci, Ellopia fasciaria ab. prasinai-ia, Cidariacyanata, 

 Hadena maillardi, a light form of Dianthcecia casia, and a fine black 

 variety of Polia flavicmcta. Dr. Dixey exhibited a series of Pierid 

 butterflies from the Neotropical region, to show the existence among 

 them of seasoual forms. The President observed that the exhibit was 

 of special interest, as affording the first recorded evidence of the 

 existence of seasonal dimorphism in Neotropical butterflies. Mr. G. T. 

 Porritt exhibited an extraordinary variety of Bombyx quercus, bred in 

 June last by Mr. W. Tunstall, from a larva found near Huddersfield. 

 The specimen was a female of deep chocolate colour, with the band 

 very faintly traced in dark olive. Dr. Chapman, Mr. Lloyd, and Mr. 

 Nicholson exhibited butterflies taken by them in Norway from June 

 20th to July 22nd, during the past summer, at latitudes 60° 12' and 

 69° 50'. It appeared from the exhibit that it would have been better 

 to collect a month or so earlier, especially in the more northern locality 

 visited. It was also seen that northern races of butterflies and moths 

 were apt to differ a little from those of the mid-European fauna, but 

 that various named varieties supposed to be characteristic boreal re- 

 presentatives of their species were often rather aberrations, and not 

 the dominant northern type. This was the case in Vanessa urtica, 

 Erebia medusa, E. ligea, &c. ; on the other hand, as in Brenthis selene 

 var. hela, the entire local race was of the variety. Papers were con- 

 tributed — by Mr. R. McLachlan, entitled " Considerations on the genus 

 Tetracanthagyna ; " by Mr. M. Burr, entitled " A List of Rumanian 

 Orthoptera ; " and by Mr. J. H. Leech on " Lepidoptera Heterocera 

 from China, Japan, and Corea." — W. F. H. Blandford, Hon. Sec. 



South London Entomological and Natural History Society. — 

 November Mth, 1898.— Mr. J. W. Tutt, F.E.S., President, in the chair. 

 Mr. Montgomery exhibited a photograph, by Mr. Clarke, of an ovum 

 of Hesperia comma ; it was smooth, without reticulations. Mr. Adkin, 

 two specimens of Dicranura bifida, taken this year in his own garden 

 on the trunk of a poplar tree. Mr. Tutt, additional local forms of 

 Zyyama, from M. Oberthur. (I.) Z.trifolii: 1, a mountain form ; 2, an 

 Algerian form, var. syracusce; 3, a coast form ; 4, a large marsh form 

 from Rennes ; and 5, series from the French coast opposite the
