extended. Had it been introduced in an artificial way, would 

 it not be probable that it would have remained strictly 

 localised, or perhaps have only lasted a certain time, and then 

 have become extinct ? "

 R. South, Esq., F.E.S., Vice-President^ in the Chair. 



Mr. Frohawk exhibited a fine bred series of Colias edusa, 

 Fb., all the females being tinged with green on the hind 

 wings ; also a living larva of Carterocephalus palcemon, PalL 

 Mr. Carrington said few entomologists had had the good 

 fortune to see the larva of this species, although he had 

 an unpublished record of it dating as far back as the 

 fifties. 



Mr. Macmurdo exhibited a series of Bryophila perla, Fb., 

 and remarked that the lichens on the wall from which they 

 were taken varied considerably. Mr. Adkin said the varia- 

 tion appeared to him to arise from an increase in the size 

 and tone of the darker markings, the whole of the specimens 

 being of a form in which the ground colour was white ; in 

 some districts the ground colour of the wings assumed a 

 yellowish or buff tint. 



Mr. Turner exhibited bred specimens of Boarmia roboraria, 

 Schiff., and stated that he only successfully hybernated two 

 larvge, although they apparently did well till the early part 

 of March. Mr. Adkin related his experience of twenty- 

 five larvae, sleeved on oak in his garden last autumn, and 

 which, in due course, attached themselves to the twigs for 

 hybernation. All went well till the middle of December, 

 when the heavy gales dislodged them ; and although they 

 gradually regained their position, taking advantage of oc- 

 casional mild days to do so, they did not appear to thrive 

 afterwards, were restless, and did not take to their food well 

 as the spring advanced. Mr. Turner also exhibited Apamea 

 ophiogramma, Esp., and a bleached variety of Epinephele 

 ianira, L., from Leigh, Essex ; he said that several specimens 

 of this form had been taken from the Leigh district within 

 the last few years. 



Mr. Allbuary exhibited a lengthy series of Colias edusa^ 

 Fb., some remarkably fine specimens of the van helice, Hb., 

 and a large specimen of Deiopeia pulcJiella, L. ; also two bred 

 specimens of Vanessa urticce, L., in one of which all the
