Entomological Society. 



in hermaphroditism ; all the hermaphrodites with which he was previously acquainted 

 had some of (heir members of the form peculiar to one sex, and some of the form pecu- 

 liar to the other sex, hut each limb was completely of one sexual form ; here, on the 

 other hand, the wing- was partly male and partly female; the wing itself was herma- 

 phrodite, the limb was gynandromorphous. It was to be noticed, moreover, that this 

 gynandromorphism did not extend through equal and corresponding portions of the 

 upper and lower surfaces of the wing, but the sexual variation in marking and colour 

 was spread over a larger space on one surface than on the other: if he might so speak, 

 the gynandromorphism was in the plane of the wing, not perpendicular to that plane, 

 and the surface of contact between the male and female portions of the limb could not 

 be traced out by the motion of a straight line kept constantly perpendicular to the 

 wing-plane. 



Professor Westwood exhibited the imago of Eucheira socialis, a Mexican species 

 whose larvae were gregarious, and the family-cocoon of which had been described by 

 him in an early volume of the Society's * Transactions.' 



Mr. Miller exhibited a specimen of QEcophora Lambdella, taken by Mr. Butters, 

 near Grays, Essex. 



Mr. Stainton exhibited some hazel leaves which had been mined by the young 

 larva; of Micropteryx fastuosella, and which he had recently gathered in the neigh- 

 bourhood of Marlborough ; there were numerous leaves bearing traces of the former 

 presence of the larva?, but in one leaf only did he find a larva actually present; careful 

 search at an earlier period of the year would doubtless lead to the breeding of the 

 species "in this country, and to a corroboration of the observations of Herr Kaltenbach. 



Mr. Stainton mentioned that during his visit to Marlborough he had had the 

 pleasure of awarding a prize which had been offered by one of the masters at the 

 College for the best collection of insects formed during the previous year. There were 

 seven competitors, each of whom, in addition to the production of his collection, was 

 put through an examination in the elementary parts of the Science; and the result 



was so satisfactory that Mr. Stainton was led to hope that] something similar would be 



done at other public schools, which would thus serve as nurseries for the Entomolo- 

 gical Societies of the Universities. 



Mr. Stainton exhibited his collection of original drawings of the larvae of Tineina, 



a portion of which, with descriptions, had already appeared in the ' Natural History 



of the Tineina,' whilst the remainder were intended for publication in the future 



volumes of that work. 



Mr. Moore exhibited some elm leaves which had been attacked by a species of 



Aphis ; and leaves of Veronica Cbamaedrys bearing galls produced by a dipterous 



larva. 



The President, on behalf of Mr. Marshall, exhibited Platyrhinus latirostris, nume- 

 rous specimens of which were sent for distribution amongst the members. 



Mr. E. Shepherd exhibited Ilyobates propinqua, Scopaeus sulcicollis and Platys- 

 tethus capito, all captured by himself near Reigate, on the occasion of the Society's 

 visit to Mr. Saunders on the 20th ult. 



Mr. Dunning read the following extract from a letter from Mr. Edwin Birchall, 

 dated Birkenhead, June 7, 1863 : — 



"I have bred three specimens of Diantheecia capsophila during the last few days; 

 the bred specimens have not a trace of brown or yellow, they are pure black and white ;
