same time he pointed out that the interpretation so convincingly illus- 

 trated that evening had been made out last spring by Mr. S. A. Neave, 

 who exhibited this form of the female vierope together with Plnnema 

 pofigei as its model at both soirees of the Royal Society in May and 

 June, a time when Mr. Trimen's absence from England unfortunately 

 prevented him from seeing them. — Dr. T. A. Chapman exhibited 

 C(Bnonymplm adipus, Satijrus dnjas, and Heteropterus morpJteiis, taken 

 last summer near Biarritz ; and Erebia evias and E. styr/ne from the 

 Logroho Sierra, Spain. These respectively he suggested were probably 

 examples of homoeochromatism. Little attention has been directed 

 to homoeochromatism in European butterflies, and these were certainly 

 not examples of the detailed mimetism we are now familiar with 

 in Miillerian groups from the African and neotropical regions. — Dr. 

 Chapman also exhibited living imagines of Ciinopteryx familiella. 

 These had just emerged at Reigate, where they and their parents, 

 descended from pupje brought from Cannes in March, 1901, had lived 

 out of doors during their active existence, being brought into the house 

 only during their pupal aestivation. This seemed noteworthy in so 

 southern (Mediterranean) a species. The experiment seemed quite 

 likely to continue successful for the next generation. — Mr. Ambrose 

 Quail read papers " On the Antennse of the Hepialidae," and " On 

 Epalxiphora axenana, Theyr." — Mr, Gilbert J. Arrow read a paper 

 "On the Laparostict Lamelicorn Coleoptera of Grenada and St. 

 Vincent, West Indies." — Mr. Thomas Harold Taylor, M.A., commu- 

 nicated "Notes on the Habits of Chiruiiomus {orthocladhis) sordidelhis." 

 Mr. F. Du Cane Godman, D.C.L., F.R.S., communicated '■ Descrip- 

 tions of some New Species of ErycinidaB." — Mr. W. L. Distant com- 

 municated " Additions to the Rhynchotal Fauna of Central America." 

 — Dr. D. Sharp, M.A., F.R.S.j read a paper " On the Egg-Cases and 

 Early Stages of some Cassididte." 



October 21si. — The President in the chair. — Mr. Montague Austin 

 Phillips, F.R.G.S., F.R.S., of 22, Petherton Road, Canonbury, N., was 

 elected a Fellow of the Society. — Mr. J. H. Keys sent for exhibition 

 a black variety of Carabus nemoralis, Miill., from Dartmoor. — Mr. G. 

 C. Champion exhibited a series of Rosalia alpina, Linn., found by him- 

 self on old beech trees at Moncayo, North Spain, in July last. — Mr. 

 A. J. Chitty exhibited the larva of Di/tiscus Jiavescens, taken at East- 

 ling, Kent. — Col. J. W. Yerbury exhibited Gastroiihilus nasalis, Linn., 

 taken at Torcross, Devonshire, from the 19th to the 31st of August 

 last. He said that as this rare species differed in a marked degree in 

 its mode of flight, &c., from the common horse bot-fly [Gastruphilus 

 equi), it would be as well to draw attention to these differences. 

 G. equi when flying round a horse visits, as a rule, the belly and the fore 

 legs. The female carries her ovipositor almost horizontal, and she 

 looks when on the wing like the lower two-thirds of the letter Z (Z.). 

 G. nasalis, on the other hand, carries the ovipositor tucked under the 

 belly and almost parallel to the axis of the body ; this gives her when 

 on the wing a peculiar ball-like appearance ; G. vasalis, too, always 

 flies to the horse's head. As a rule, the cart-horse under observation 

 paid no attention to G. equi, but G. nasalis caused it great alarm. 

 The eggs of G. equi were in hundreds on the shoulders and fore legs ; 

 but although the face and nostrils were searched carefully, no eggs or
