 MARCH 26th, 1903. 



The President in the Chair, 



Mr. E. Warne, of St. John's Hill, Clapham, was elected 

 a member. 



Mr. Jennings exhibited a series of the very local Crypto- 

 ccphalns hipiinctatus, L. (v. lincola, F.), taken at Charing, Kent, 

 in June, 1902, on hazel bushes. 



Mr. Colthrup exhibited hybernating colonies of the larvas 

 of Purthesia chrysorrhcca, from Newhaven, where similar 

 colonies could be found in almost every hedge. The larvae 

 were already beginning to wander, no doubt from the warmth 

 of the weather just experienced. 



Mr. W. J. Kaye exhibited the two remarkable Ithomiines, 

 Mctlwna confusa and Thyridia psidii, from the Essequibo 

 river, British Guiana, two butterflies which so closely 

 resemble one another that they can scarcely be distin- 

 guished except by the neuration. A specimen of the 

 Mcthona was also shown from Paraguay, where the- 

 black markings are less intense, and where also the Tliyridia 

 has undergone a similar change. Professor Poulton had 

 referred to this remarkable instance in his recent address to 

 the Society. 



Mr. R. Adkin exhibited a very dark specimen of Sinerin- 

 thus populi, bred from a larva found at Bexley, Kent. Com- 

 pared with a normal Kentish example and one from Suther- 

 land, which were exhibited with it for the purpose, it was 

 considerably darker than either, not only in the olive-grey 

 markings of the fore-wings, but also in the red patch of the 

 hind-wings. In this latter respect it much more closely 

 resembled the Scotch than the Kentish form. 



Dr. Chapman exhibited specimens of the Dipteron 

 Lasioptera ruhi, a Cecidomyid, that makes swellings in the 

 stems of brambles. They were bred from a gall taken recently 

 at Reigate. 



Mr. Hy. J, Turner exhibited a large number of species of 

 various orders of insects, collected at Amersham at the end 

 of June, igo2, and read notes on the district and its fauna 

 and flora (see p. 3).
