325i THE ENTOMOLOGIST. 



nests, caught in specially constructed traps, the largest male reaching 

 the abnormal size of 32 mm.; (b) Anthaxia nifidnla, L., twelve speci- 

 mens taken in July, one being of bluish colour; (o) Agrilus mmattis, 

 01., one of several which escaped — a beetle not taken for many years ; 

 (d) Ayriiis viridis, L., a series from sallows in August ; (e) Piatydema 

 violaceuni, F., five specimens — a species also not recorded recently; 

 (/) Colij/dium elongntuin, F., one specimen taken in the burrows of 

 Melanin huprestoides, and another in the burrows of Scoli/tus intricatus. 

 Mr. Champion said that Fhitiidcma had been taken twenty years ago 

 by Harris, while Mr. George Lewis associated Vclleius with Cossns, and 

 not with hornets. — Mr. C. P. Pickett exhibited a long series of Lycana 

 corydon taken during August, 1901, at Dover, varieties and aberrations, 

 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 Anycrona primaria (bred June and July, 

 1901), the results of four years' interbreeding, the colouration 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 bauds to deep chocolate with bands, while one male assumed the 

 coloration of the female. — Prof. T. Hudson Beare exhibited a specimen 

 of Medon castant'iis, Grav., taken in a 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. Very few observations of 

 this beetle have been recorded, and they all seem, as in this case, to 

 have been chance captures, its habits being unknown. — Mr. A. Harrison 

 exhibited a series of Amphidnsy.s hetidaria bred from parents taken in 

 the New Forest in 1900, including twenty males and thirty-nine 

 females, and six gynandromorphous specimens, out of seven bred, 

 one being a cripple. The larvae when first hatched were kept indoors, 

 but were afterwards sleeved on birch when a few days old. Mr. Tutt 

 said it was very remarkable that so many gynandromorphous specimens 

 should have been secured from a single brood. There appeared to be 

 frequently modification in the sexual organs corresponding with ex- 

 ternal variation of the secondary sexual cliaracters. Mr. Merrifield 

 remarked that the proportion of gynandromorphous forms in hybrid 

 specimens was always much larger. — Mr. C. J. Gahan exhibited a 

 male specimen of Tliamnutrizon vinerens, L.. one of the long-horned 

 grasshoppers taken by Mr. F. W. Terry at Morden, near Wimbledon. 

 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 tibiffi of the middle legs in 

 a position corresponding with that of the normal pair on the fore legs. 

 — Mr. F. Merrifield exhibited a series of 0. antiqna bred from pupae 

 placed in a refrigerator five weeks and then exposed to a mean tempe- 

 rature 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 i). yonostigma. He also exhibited for comparison speci- 

 mens from Sutherlandshire, lent by Mr. C. G. Barrett, none of them, 

 however, comparable in darkness to those obtained by his experiment; 

 and otliers from the collections of Mr. A. Bacot (including four of the 

 American species) and Mr. L. B. Prout. Mr. Tutt said that the limits 

 of variation in our own form were little known, and the most northern
