Tutt said that he had repeatedly seen the yellow form of C. 

 dominula on the Continent, but that it was undoubtedly rare 

 in this country. With regard to A. grossulariata, he said 

 that Mr. Merrifield had remarked how commonly the species 

 was found feeding on the Euonymus in the squares of Brighton. 

 Mr. Adkin said that years ago it was most abundantly found 

 on hawthorn, and Mr. West had taken it commonly on 

 spindle. 



Mr. Dennis exhibited specimens of the filmy fern, Hymcno- 

 phyllum wilsoni, from Wales. It was found in much drier and 

 more exposed situations than its close ally, H. tunbridgcnsc. 



Mr. H. Moore exhibited a series of blue females of Polyom- 

 matus {Lyccena) icarus from Folkestone. Mr. Tutt remarked 

 that in the south of Europe he had very rarely seen blue- 

 marked females ; they were nearly all of the dark type form 

 of the sex. 



Mr. Mansbridge exhibited a series of under sides of the 

 female of Plebius (Lyccena) cegon, selected to show the ordinary 

 range of variation in the species as it occurred in St. 

 Leonard's Forest. He was of opinion that with most of the 

 blues the females were getting more blue than they were 

 years ago. He related a curious experience that had 

 happened to him with both Polyommatus {Lyccena) icarus 

 and P. agon, viz. that of a male taking up the position of a 

 female, and actually attracting other males. That these were 

 males he verified by capture. Mr. Tutt referred to P. argus, 

 and stated that although the difference of these two species 

 from each other was so slight that some entomologists 

 considered them specifically identical, yet even when they 

 occurred in the same valley they were perfectly distinct as 

 regards locality. 



Mr. Montgomery exhibited an exceedingly fine dark suf-
