154 THE ZOOLOGIST. 



Entomological Society of London. 



March Ath.—~W. F. H. Blandfoed, M.A., F.Z.S., V.P., in the chair. 



Mr. P. Marshall, of Canterbury College, Lincoln, N.Z., was elected a 

 Fellow. 



Mr. P. H. Grimshaw exhibited specimens of Cephenomyia rujibarbis, 

 Meigen, a new British Bot-fly parasitic on the Red Deer in Scotland. 



Mr. C. G. Barrett exhibited, for Mr. Porritt, a black variety of Folia 

 flavicincta, taken at sugar in his garden at Huddersfield ; a variety 

 of Cosmia trapezina with a blue-black central band ; and a variety of Mania 

 typica with pinkish white central markings, bred by Mr. Turnstall, of 

 Huddersfield. 



Mr. A. H. Jones exhibited specimens of the following butterflies, 

 captured at Coomassie by Major Henry P. Northcott during the recent 

 expedition, viz. Papilio zenobia, Elymnias bammakoo, Limnas alcippus, 

 Romaleosoma gausape (var.), Catuna camobita, Terias sengalensis, and 

 Neptis nemeies. 



Sir John T. D. Llewelyn, Bart., M.P., exhibited specimens of a small 

 species of Diptera which he believed to be parasitic on Trochilium 

 sphegifornte, as he had bred a number from that species. T. spliegiforme, 

 although one of the most local moths in this country, had occurred last 

 year at Dolau Cothy, Carmarthenshire, in such numbers in the larval state 

 as almost to destroy the whole of the alders growing there. Mr. G. H. 

 Verrall said that the insects belonged to a species of Phora, possibly Phora 

 rufipes, practically omnivorous, but not considered to be truly parasitic. 



Mr. Hampson exhibited an exotic species of Locust which Lord 

 Walsingham had found in his conservatory at Merton Hall, Norfolk, where 

 no exotic plants had been imported for some years. 



Dr. Sharp exhibited specimens of the pupae of Micropteryx (probably 

 semipurpurella), and drawings to illustrate their structure. Mr. McLachlan 

 said that so long ago as 1865 he had suggested the close affinity of Micro- 

 pteryx to the Trichoptera ; the opinion then formed had since been much 

 strengthened, but he was not disposed to admit co-ordinal relationship. 



Mr. McLachlan exhibited a singular instance of monstrosity in a 

 Dragon-fly. The insect was a male of Hetarina occisa, Hag., from 

 Venezuela. On the left side were three wings, two mesothoracic and the 

 other metathoracic ; on the right side only one wing, the metathoracic. 

 The supplementary wing on the left side was inserted almost immediately 

 beneath the ordinary wing ; it was normal in form and neuration, but the 

 red pigment at the base (fully developed in all the other wings) was not 

 evident, the wing in this respect being similar to those of highly immature 

 examples of the same species. 



Mr. E. E. Green exhibited a larva of an homopterous insect — one of the
