Entomological Society of London : October 'Znd, 1901. — The Rev. Canon 

 W. W. FowLEE, M.A., F.L.S., President, in the Chair. 



Mr. G. C. Champion exhibited a long series of Buprestis sanguinea, Fabr., 

 from Albarracin, Spain, showing the remarkable sexual dimorphism of this 

 species. Mr. H. St. J. Donisthorpe, on behalf of the Eev. H. S. Gorham, of 

 Shirley Warren, a specimen of Hister marginalus ; Mr Champion remarked that 

 the species had been taken by Mr. llarwood, at Colchester ; he also exhibited a 

 number of rare Coleoptera from the New Forest : — {a) T'elleius dilatatus, F., twelve 

 specimens, ten from one iiornot's nest in August, and the other two from two other 

 nests, caught in specially constructed traps, the largest ^ reaching the abnormal 

 length of 32 mm. ; (b) Anthaxia nitidula, L., twelve specimens taken in July, one 

 being of bluish colour ; (c) Agrilus sinuatux, 01., one, several others escaped — a 

 beetle not taken for many years ; {d) Agrilus viridis, L., a series from sallows in 

 August; (e) Pldti/dema violaceum, ¥., &ve specimens— a, species also not recorded 

 recently ; (/) Colydium elongatum, F., one specimen taken in the burrows of 

 Melasis buprestoides, and another in the burrows of Scolgttts intricatus. Mr. 

 Champion said that Plafgdenia had been taken about twenty years ago, while 

 Mr. George Lewis associated VeUeius with Cossiis, in Japan, and not with hornets. 

 Mr. C. P. Pickett, a series of varieties and aberrations of Lyccena Corydon taken 

 during August, 1901, at Dover, including two females with upper wings wholly 

 blue, dwarfs no larger than L. minima, and others (males) with under-sides 

 devoid of spots ; he also exhibited a, series of Angerona prunaria (bred June and 

 July, 1901), the results of four years' interbreeding, the coloration ranging, in the 

 females, from bright yellow with no bands to very dark with deep chocolate bands, 

 and in the males from plain intense orange with no bands to deep cliocolate with 

 bands, while one male assumed the coloration of tiie female. Prof. T. Uudsoii 

 Beare, a specimen of Medoii castaneus, Grav., taken in the water-net on April 22nd, 

 1901, at the edge of a pond in Richmond Park. Mr. A. Harrison, a series of 

 Amphidasys betularia bred from parents taken in the New Forest in 1900, in- 

 cluding twenty males and thirty-nine females, and six gynandromorphous specimens, 

 out of seven bred, one being a cripple. Mr. Tutt said it was very remarkable that 

 so many gynandromorphous specimens should have been secured from a single 

 brood. There appeared to be modification in the sexual organs corresponding with 

 external variation of the secondary sexual characters. Mr. Merrifield remarked 

 that the proportion of gynandromorphous forms in hybrid specimens was always 

 much larger. Mr. C. J. Gahan, a male specimen of Thamnotrizon cinereus, L., one 

 of the long-horned grasshoppers taken by Mr. F. W. Terry at Morden, near Wim- 

 bledon ; he called attention to a very interesting abnormality displayed by the 

 specimen in possessing two pairs of auditory organs instead of a single pair, the 

 second pair being situated on the tibiae of the middle legs in a position correspond- 

 ing with that of the normal pair on the fore-legs. Mr. F. Merrifield, a series of 

 Orgyia antiqua bred from pupse placed in a I'efrigerator five weeks, and then exposed 

 to a mean temperature of 48^ Fahr. Specimens thus treated were much darker 

 than types of those occurring in a natural state, some approaching in depth of 

 colouring to O. gonostigma. He also exhibited for comparison specimens from
