scmguinea, Fabr., from Albarracin, Spain, showing the remark- 

 able sexual dimorphism of this species. 



Mr. H. St. J. Donisthorpe exhibited on behalf of the 

 Rev. H. S. Gorham of Shirley Warren, a specimen of the 

 scarce beetle Hister marginatus. Mr. Champion remarked 

 that the species had been taken by Mr. Harwocd of 

 Colchester. He also exhibited a number of rare coleoptera 

 from the New Forest — (a) Velleius dilatatus, F., twelve speci- 

 mens, ten from one hornets' nest in August, and the other 

 two from two other nests, caught in specially constructed 

 traps, the largest <$ reaching the abnormal size of 32 

 m.m. : (b) Anthaxia nitidula, L., twelve specimens taken 

 in July, one being of bluish colour: (c) Agrilus sinuatits, 01., 

 one of several which escaped — a beetle not taken for many 

 years : (d) Agrilus viridis, L., a series from sallows in 

 August : (e) Platydema violaceum, F., five 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 Scolytus intricatus. Mr. 

 Champion said that Platydema had been taken twenty years 

 ago by Harris, while Mr. George Lewis associated Velleius with 

 Cossus in Japan and not with hornets. 



Mr. C. P. Pickett exhibited a long series of varieties and 

 aberrations of Lycsena 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 

 undersides devoid of spots. He also exhibited a series of 

 Angerona pnmaria (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 chocolate with bands, while one 

 male assumed the coloration of the female. 



Prof. T. Hudson Beare exhibited a specimen of Medon 

 castaneus, Grav., taken in the water net on April 22nd, 1901, 

 at the edge of a pond in Richmond Park, having evidently 

 come off the long grass growing at the edge of the water. 

 Yery few observations of this beetle have been recorded, and
