Entomological Society of London : December 7th, 1898. — Mr. R. Teiuen, 

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



Monsieur Leon Candeze, of 64, Rue de I'Ouest, Liege ; Mr. C. L. B. Stares, 

 M.R.C.S., L.R.C.P., of the Infirmary, Wandsworth, S.W. ; Mr. A. Russell, of The 

 Limes, Southend, Catford, S.E. ; 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 dragon-flies, though it was slightly exceeded in 

 wing-area by the much more slender Megaloprepus carulatus, a common Central- 

 American species. Mr. A. H. Jones, about sixty species of Lepidoptera, taken 

 round electric light at Zermatt, in August. Among the more interesting were 

 Crateronyx taraxaci, Ellopia fasciaria, ab. prasinaria, Cidaria cyanata, Hadena 

 Maillardi, a light form of Dianthcecia ccesia, and a fine black variety of Polia 

 Jlavicincta. Dr. Dixey, a series of Pierid butterflies from the Neotropical region to 

 show the existence among them of seasonal 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, an 

 extraordinary variety of Bombyx querciis, bred in June last by Mr. W. Tunstall, 

 from a larva found near Huddersfield ; the specimen was a female of deep choco- 

 late colour, with the band very faintly traced in dark olive. Dr. Chapman, Mr. 

 Lloyd, and Mr. Nicholson, 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 representatives of their species, were often rather aberrations, and not the 

 dominant northern type. This was the case in T'anessa iirticee, Erebia Medusa, 

 E. ligea, &c. ; on the other hand, as in Brenthis Selene, var. llela, the entire local 

 race was of the variety. Papers were contributed by Mr. R. McLachlan, entitled, 

 "Considerations on the genus Tetracanthagyna ;" hy Mr. M. Burr, entitled, " A 

 List of Rumanian Orlhoptera ;" and by Mr. J. H. Leech, on " Lepidoptera Hetero- 

 cera from China, Japan, and Corea."— W. F. H. Blandfokd and F. Meurifield, 

 Hon. Sees.
