adaptation of the electric light for microscopical and surgical 

 purposes. 



Mr. Dadswell and Mr. Macer, who were present as 

 visitors, also exhibited, the former botanical, and the latter 

 entomological objects. 



APRIL \^th, 1887. 

 R. Adktn, Esq., F.E.S., President, in the Chair. 



Mr. C. A. Briggs exhibited a large number of Lyccena 

 bellargus, Rott., including many forms of the male and 

 female, dwarfed forms, and some remarkable varieties of the 

 under side ; also a pale yellow variety of L. cEgon, L., and 

 varieties of the under side of L. icarus, Rott., and L. astrarche, 

 Bgstr., of which the following were the most important : — 



Var. of L. {astrarche) medoit, U. S, 



Ground colour of all the wings pearly white, shaded in 

 parts with pale ash colour. The marginal row of red spots 

 very bright and distinct, owing partly to the absence of the 

 usual outer row of black dots. 



Except the central spot on each fore wing, and three 

 spots — of which two are very minute — on each hind wing, the 

 usual black spots are entirely absent. 



The specimen was captured near Dover in 1878. 



L, icarus c?, U. S. 



Very similar to the preceding. All four wings pearly 

 white, shaded in parts with dark grey. All the black spots 

 absent, except the central one in each wing. The red marginal 

 band of spots normal, the row of black points outside them 

 in the fore wings very faint, and the inner crescentic row 

 unusually strongly marked. 



Captured near Dover in 1879. 



Mr. Goldthwaite exhibited living larvae of Pericallia 

 syringaria, L. 



Mr. R. Ad kin exhibited several pupa cases of Eupczcilia 

 ambiguella, Hb., from the New Forest, and commented upon 

 their similarity to the bark of the twigs and stem of the 

 Alder Buckthorn {Rhamnus frangula), to which they were 

 attached.
