intermediate forms. Darwin gives analogous instances in 

 chap. XV. of his * Variation of Animals and Plants under 

 Domestication.' But the question how far this tendency to 

 resemble the parents goes has never been definitely settled, 

 and much may yet be done — by experimental crossing — to 

 determine the point. Will not those Lepidopterists who 

 breed so many insects annually take this matter up .? They 

 might without much difficulty obtain crosses between varieties 

 of several species, and the results, if recorded and tabulated 

 when numerous, would furnish statistics more powerful than 

 any amount of argument from probabilities. 



NOVEMBER 2%th, 1889. 

 T. R. BiLLUPS, Esq., F.E.S., President, in the Chair. 



Messrs. M. Cameron, C. G. Barrett, F.E.S., F. P. Trewicke, 

 A. V. Legros, L. W. Harris, A. J. Robertson, C. H. Lemmon, 

 W. Howgrave, L. H. Strong, and W. E. Nicholson were elected 

 members. 



Mr. Jenner Weir exhibited specimens oi Lininas cJirysippus, 

 L., and HypoUmnas iiiisippus, L., and remarked that there 

 were four specimens of H. misippus and four of L. chrysippiis- 

 alcippus, Cramer, which he had received from Dr. Percy 

 Rendall, from the Gambia ; one of the females of the former 

 was a mimic of Limnas chrysippiis, one of Limnas chrysippus- 

 alcippus, and the other intermediate between the two, the 

 white of the under wings characteristic of the latter being 

 reduced to a spot. Dr. Rendall informed him that he had 

 never seen a specimen of the typical L. chrysippnis in the 

 district, so it might be suggested that a widely distributed 

 species as H. misippus had reached the Gambia subsequent 

 to the differentiation of Z. alcippus, and that the mimicry had 

 in some specimens not yet commenced, in others it was in- 

 cipient, and in some complete. 



Mr. Weir also exhibited Limnas dorippus, Klug., from 

 Eastern Africa, and a female mimic of HypoUmnas misippus ; 

 Limnas chrysippus from Ceylon, and its mimic HypoUmnas 

 7nisippus ; Limnas cJirysippus from Natal, with a white spot 

 on the under wing similar to that of the intermediate female 

 of HypoUmnas misippus referred to above.
