ABSTRACT OF PROCEEDINGS. 



FEBRUARY nth, 1904. 



Mr. A. SiCH, Y.'E.S., President, in the Chair. 



Mr. Montgomery exhibited examples of Ocneria dispar, in 

 which a large semicircular portion at the apex of each hind 

 wing was wanting. He stated that a friend was breeding 

 the insect in some numbers, and a few of this aberrant form 

 appeared. Two of them were paired, and nearly the whole 

 of the progeny of this pair \i'ere similarly affected. Mr. Enock 

 remarked that in 1878 he had a brood of the same insect, 

 which showed exactly similar characteristics. 



Mr. South exhibited several albino and xanthic aberra- 

 tions of Epincphele tHhomis. The specimens were taken by 

 Mr. G. M. Russell on the Chalk Downs in S. Hampshire, 

 one in 1898, two in i8gg, six in igoo (species abundant in 

 1900). The yellow specimens seem to be referable to ab. 

 mincki, Seebold. For the whitish form, Mr. Verity of 

 Florence, Italy, who took two ^ and one ? examples in 

 August last on Mount Matanna, proposes the name subal- 

 bida. Mr. Verity has also named a similar form of E. ida 

 as ab. albida, the latter from the Tuscany coast. 



Mr. Kaye exhibited several photographs of the Potara 

 river, British Guiana, and made remarks on the localities 

 adjoining. 



Mr. Robert Adkin exhibited a series of Lencoma {Liparis) 

 salicis reared from pupae collected in July last at Heme Bay, 

 Kent. He said that his chief object in making this exhibit 

 was to obtain information. The pupae were sent to him by 

 Mr. Lachlan Gibb, who during a visit to Heme Bay found 

 the pupae in great numbers in folded leaves of the poplar- 

 trees that grow near the sea front. Mr. Gibb had told him 

 that while on a similar visit in igoi he had noticed the 

 moths swarming about the same trees ; so abundant were
