than the ab. rondoui. The males are, however, nice varieties with 

 discal spots and marginal chevrons. 



Also living specimens of Aphidius ervi, Halliday, from the Aphis 

 of (hwnis arreiisis. It would appear that each species of Aphis has 

 an Aphidius more or less attached to it only — forming an interesting 

 field of observation to anyone tired of the more beaten track. 



Mr. B. S. Curwen exhibited some first brood females of 

 Polyommatiis icarus from Pigott's Hole, Eanmore Common, all of 

 which were much suffused with blue scaling. Two specimens were 

 of the underside aberration melanotoxa (arcuata). 



Dr. Chapman called attention to the fact that a large proportion 

 of the females of Polyonnnatns icarus in Mr. Curwen's exhibit had 

 the conspicuous wedge-shaped submarginal blotch of light colour 

 faithfully reproduced on the upperside. 



Mr. A. Sich exhibited coloured drawings, beautifully executed by 

 himself, of the larvae of the British species of the genus Acronicta, 

 and referred to the figures of the larva) of Tricena (A.) ])si and 

 T. tridens, with remarks on the various points of wide difference of 

 the two species at this stage contrasted with their extreme 

 similarity in the imaginal stage. 



Mr. B. W. Adkin exhibited a large series oi Apaturairis and made 

 remarks on the species as it occurred in Britain. He stated that he 

 considered this species showed far greater variation than is 

 generally supposed, and but for its rarity, would be a far more 

 variable insect than many of our other species of British butterflies. 



Two of the specimens shown approached ab. iole, a male had a 

 brown costa, and a female with heavily marked brown costa had 

 much brown suffusion over both fore- and hindwings. 



Mr, Gibbs said that A. iris formerly occurred in Hertfordshire, 

 and that Stephens in his "Illustrations," recorded its presence near 

 Hertford in July, 1833. It was reported to still linger on in the 

 county, and Dr. A. H. Foster, of Hitchin, had informed him that 

 he had seen a specimen in 1899 or 1900, just outside Hitch Wood. 

 Gamekeepers in some of the large Hertfordshire woods confirmed 

 Dr. Foster's statement, for they said very positively that they 

 occasionally saw a large purple butterfly, settling on dead birds, 

 rats, etc., hanging in their " larders." Mr. Gibbs much hoped to 

 be able to report some day the capture of iris in a locality so near 

 to London. 



Mr. Turner said that one of the old localities was near East 

 Grinstead, Sussex, but he had sought for it there in vain, and local 

 report said that it had disappeared many years before.
