Horsley, showing a complete gradation in the number and development of the spots 

 on the under-side, and also one upper-side well scaled witli blue. Mr. Fremlin, 

 specimens of Polyommatus Astrarche v. Salmacis, from Castle Eden Dene. Mr. 

 Mansbridge, varieties of Abraxa.i grossularlata bred from larvae obtained at Hors- 

 forth. Out of 150 larvae two or three per cent, only showed a more than ordinary 

 variation, compared with some fifteen per cent, last year from the same locality. 

 Two specimens were asymmetrical, and one was a nicely radiate form. Mr. West 

 (Greenwich) exhibited specimens of the Hemipteron, Dicyphns epilobii from 

 Eltham. Mr. Moore, a specimen of the second brood of Cyaniris Argiolus, taken 

 on July 12th at O-xshott, and also a specimen of Plebeius Mgon, destitute of the 

 row of fulvous blotches on the upper surface, and one having confluent spots on the 

 under-side. Mr. Eobt. Adkin contributed a paper, entitled, " Notes and Observa- 

 tions made during the Society's Field Meeting at Chalfont Road, on July 18th, 

 1896." 



August IZth, 1896.— C. Gr. Barrett, Esq , P.E.S., Vice-President, in the Chair. 



Mr. S. Stevens exhibited an unusually small specimen of Papilio Machaon, 

 having the black band on the hind-wings very narrow. Mr. R. Adkin, a bred series 

 of Pachnobia hyperborea, from pupse taken at Rannoch. Mr. McArthur, a preserved 

 larva of the same species, mounted on a twig of its food-plant {Empetrum nigrum), 

 the crowberry, and gave interesting details as to its life-history. Mr. Fremlin, a 

 series of Phigalia pedaria from Saltash, including the dark reticulated form and the 

 very dark uniform variety. Mr. H. Moore, numerous interesting insects from South 

 Africa, including a fine specimen of Actias mimosce, which, from its sluggish habits, 

 can be easily picked off the bushes, its larvae are more or less gregarious ; several 

 species of the larger Orthoptera, Pachytylus pardalinus, the locust which often 

 appears in vast numbers, and does considerable damage ; P. peregrinus, which is the 

 locust of North Africa ; Cyrtacanthus purpurifer, a very large species ; Acheta 

 africana, a cricket from Johannesburg ; and numerous species of Coleoptera, 

 which are attracted in thousands by the electric light in Pretoria. Mr. Sau^e, a spe- 

 cimen of Cicadetta montana, one of three taken by Mr. Heasler in Surrey. Mr. Heasler 

 had been attracted to some oak trees by an unusual stridulation, and eventually suc- 

 ceeded in obtaining these three examples. Mr. West, of Greenwich, a series of the 

 local Hemipteron, Eurygaster maura from Folkestone. Mr. Mansbridge, a double 

 cocoon of Clisiocampa neustria, from which, although the imagines had emerged from 

 the pupa cases, they had been unable to extricate themselves ; when cut open there 

 was only one cavity partially divided into two. Mr. Barrett exhibited four British 

 specimens of Plusia ni, two belonging to Mr. Jeffrey and two to Mr. C. A. Briggs ; 

 one of the former was captured in Surrey ; also from Mr. Jeffrey a fine variety of 

 Cleoceris viminalls, h&v'mg the basal half of the fore-wings very dark in contrast to 

 the very pale outer portion ; and a remarkable form of Agrotis exclamatioyiis, in 

 which neither of the stigmata was developed, but the elbowed and basal lines were 

 very distinct and perfect on the uniformly pale brown ground-colour. A discussion 

 took place on the season, with special reference to Colias Edusa and the means of 

 migration of insects. Messrs. Stevens, McArthur, Adkin, Barrett, Mansbridge, 

 Winkley, and others taking part. — Hy. J. Turner, Hon. Secretary.
