Birmingham Entomological Society : Ocfober 2\st, 1907.— Mr. G-. T. 

 BETnuNE-BAKER, President, in the Chair. 



The Rev. C. F. Thornewill showed various Lepidoptera collected at Arrochar 

 this year, including Larentia trintata, L., two specimens of a nice form, with 

 cream-coloured ground and coffee-coloured markings. He said that in daylight the 

 markings had quite a golden tinge. The form of the markings was normal, except- 

 ing that the central band was restricted. Also included in the collection were 

 L. ad;equala, Blch. (blandiata, Hb.), of which he took a long series, and an 

 unrecognised Eupithecia. Mr. J. T. Fountain, a long series of Bryophila perla,J?., 

 and muralis, Forst., from many British localities to illustrate the extent of their 

 variability. Mr. Colbran J. Wainwright, two specimens of Platychirus albi- 

 mantis, ¥., from Sutton Park, which were quite extraordinary. They were melanie, 

 one showing no trace of markings, and in different degrees they showed characters 

 intermediate between those of the male and the female sexes. Strictly speaking, 

 they were probably not gynandromorphs, as they did not exhibit some parts 

 definitely male and others definitely female ; they would perhaps be better 

 described as females, which in some respects varied in the direction of the male 

 secondary characters. The chief points were, (1) the width of the foreheads, which 

 were only about half the width of those in normal females, and in details of out- 

 line resembled those of males and not females; and (2) the fore tarsi and tibia;, 

 which, instead of being quite simple as in normal females, showed decided widen- 

 ing, in this respect approaching those of normal females (in different degrees in the 

 two specimens). The genitalia outwardly appeared female. Mr. G. T. Bethune- 

 Baker, a nice collection of butterflies of the genus Pararge, with the various forms 

 of segeria, L., inegxra, L., masra, L., &c — Colbran J. Wainwright, Hon. Sec.

 of the Session was held at the Society's Booms in the Royal Institution, Colquitt

 President, in the Chair. 



Mr. A. E. Gibbs, F.L.S., F.E.S., of St. Albans, was elected a Member. 



This being the Annual Exhibition Meeting, many interesting insects were 

 brought by the Members. Mr. B. H. Crabtree exhibited a fine series of the local me- 

 lanie form of Boarmia repandata from Penmaenmawr, the females especially showing 

 the white blotches characteristic of this local race; B.gemmaria var. perfumaria 

 from Manchester ; varieties of Atigerona prunaria from Monks wood ; Aplecta nebti- 

 losa var. robsoni from Delamere Ft. ; Agrotis ashworthii from Penmaenmawr ; and 

 Chariclea umbra from Sidmouth. Mr. Robert Tait, jun., a number of local species, 

 among them being a long series of Agrotis ripse from South Wales coast, A. ash- 

 worthii, North Wales, a long series captured at rest ; Hemerophila abruptaria, the 

 chocolate form from the London district ; Lobophora viretata, Anticlea derivata, 

 and Larentia salicata from Lake Side, Westmoreland ; Dianthoecia nana and Eupi- 

 thecia jasioneata from Abersoch. Dr. Wm. Bell, a drawer of beautifully preserved
