32'2 THE ENTOMOLOGIST. 



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

 the abnormal size of 32 mm.; (i) Anthaxia nit'uUtla, L., twelve speci- 

 mens taken in July, one being of bluish colour; (c) Arjrilns siniiatiis, 

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

 {(/) Aijrilis viridis, L., a series from sallows in August ; (c) Piatj/'leuia 

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

 (/) Colydium elonijatimi, F., one specimen taken in the burrows of 

 Melasis bnprestoidcx, and another in the burrows of Scolytus iiitricatus. 

 Mr. Chainpion said that Pliti/doiia had been taken twenty years ago 

 by Harris, wliile Mr. George Lewis associated Velleius with Oossns, and 

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

 cori/don 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 devoi^ of spots. 

 He also exhibited a series of Aiujcruiia pnniuria (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 bands to deep chocolate wath bands, while one male assumed the 

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

 of Medon castaneus, 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 Aiiip/tidi(si/s betnlarin bred from parents taken in 

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

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

 one being a cripple. The larvfe 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 gynaudromorphous 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 characters. 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 Thamnotrizon cineicus, 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 sitv;ated on the tibife 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 (). antiqua 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 (). t/onostit/nia. 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 others 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
