360 THE ZOOLOGIST. 



Messrs. W. and A. K. Johnston, as can also the Royal Agricultural Society's 

 coloured diagram of the potato disease. The technical education com- 

 mittees of County Councils and other bodies interested in agricultural 

 instruction will render useful service by circulating these diagrams in rural 

 districts. 



Entomological Society of London. 



August 5, 1891. — Mr. Frederick Du Cane Godman, M.A., F.R.S., 

 President, in the chair. 



Mr. Arthur J. Chitty, of 33, Queen's Gate Gardens, S.W., and Captain 

 E. G. Watson, of 5, Lypialt Terrace, Cheltenham, were elected Fellows. 



The President announced the death of Mr. Ferdinand Grut, the Hon. 

 Librarian of the Society, and commented on the valuable services which 

 the deceased gentleman had rendered the Society for many years past. 



Dr. D. Sharp exhibited Japyx solifugus, from the Eastern Pyrenees, 

 and stated that in his opinion it was a connecting link between the 

 Thysanura and Dermaptera. He also exhibited pupae of Dytiscus mar- 

 ginalis ; one of these was perfectly developed, with the exception that it 

 retained the larval head : this was owing to the larva having received a 

 slight injury to the head. Dr. Sharp also exhibited specimens of Ophonus 

 puncticollis and allied species, and said that Thomson's characters of the 

 three Swedish species, 0. puncticollis, 0. brevicollis, and 0. rectangulus, 

 applied well to our British examples, and separated them in a satisfactory 

 manner. Thomson's nomenclature, however, would he thought prove 

 untenable, as the distinguished Swede described our common puncticollis 

 as a new species under the name of rectangulus. 



Mr. F. W. Frohawk exhibited a bleached specimen of Epinephele 

 janira, having the right fore wing of a creamy white, blending into pale 

 smoky brown at the base; also a long and varied series of Epinephele 

 hyperanthus, from the New Forest and Dorking. The specimens from the 

 former locality were considerably darker and more strongly marked than 

 those from the chalk. Amongst the specimens was a variety of the female 

 with large lanceolate markings on the under side, taken in the New Forest 

 in July, 1890, and a female from Dorking with large, clearly defined white- 

 pupilled spots on the upper side. Mr. Frohawk further exhibited drawings 

 of varieties of the pupae of E. hyper anthus, and also a large specimen of a 

 variety of the female of Euchloe cardamines, bred from ova obtained in 

 South Cork, with the hind wings of an ochreous-yellow colour. Coloured 

 drawings illustrating the life-history of the specimen in all its stages were 

 also exhibited. 



Mons. Serge Alpheraky communicated a paper entitled " On some cases 

 of Dimorphism and Polymorphism among Palaearctic Lepidoptera." —
