— the division of sex in the hind wing being shown in the 

 colour between two of the nervures, and also in their struc- 

 ture. Mr. Barrett also exhibited the following, lent by Mr. 

 F. Merrifield, of Brighton : Two broods of Vanessa levana^ 

 L., and Vanessa c~album, L., showing seasonal dimorphism 

 produced from the same batch of ova by means of artificial 

 heat and cold ; Vanessa polychloros, L., darker specimens than 

 any found at large, the result of slow development under a 

 cool temperature ; Vanessa io, L., showing obliteration of the 

 ocellus in the fore-wing, and increase of the blue spots, arti- 

 ficially produced. 



Mr. South exhibited a specimen of Ortkotcenia antiquana, 

 Hb., taken 28th June, 1893, on a shop window in St. John's 

 Wood ; also long series of Pyrausta purpuralis , L., and P. 

 ostrinalis, Hb., which he said he considered might possibly 

 be phytophagous forms of one species, several of the spe- 

 cimens he exhibited being intermediate between the two 

 species. He mentioned that the larva of P. ostrinalis^ ap- 

 peared to be undescribed, but that it probably fed on thyme 

 or catmint. A considerable discussion ensued as to the 

 specific distinctness of these two species, Mr. Tutt and others 

 taking the opposite view to that expressed by Mr. South, Mr. 

 Tutt stating that he never knew the two species to be cap- 

 tured together. 



Mr. B. W. Adkin exhibited a pair of Leiicania vitellina, 

 Hb., and a remarkably fine specimen of L. extrema, Hb., all 

 taken in the Scilly Isles in September last. 



Mr. Auld showed a specimen of Vanessa atalanta, L., 

 having the band on one hind-wing, orange, and on the other, 

 red. 



Mr. C. A. Briggs exhibited a female Lyc<2na bellargus, Rott. 

 autumn brood, from Folkestone, it being as bright a blue as 

 any male specimen. Mr. Weir remarked that these blue 

 females appear to be found more particularly in some localities 

 than others. 



Mr. A. W. Dennis exhibited examples of a partial third 

 brood of Pararge megcera, L., the remainder of the brood 

 hybernating as young larvae. 



Mr. Turner showed three very fine specimens of the Scotch 

 form of Arctia menthastri, Esp. 



Mr. J. M. Adye showed a specimen oi Deilephila livornica, 

 Esp., captured at Christchurch on the 25th May, 1893.

 data, L., from the south of Ireland, one specimen being 

 exceedingly dark.
