among the butterflies or the Noctuae, but he thought con- 

 siderable interest attached to the extreme forms of Geometrae 

 (see Entomologist xxv., pp. 105-110). 



Mr, Barrett called attention to the forms of C<2nonympha 

 typhon, Rott., which, he said, were rather the extreme of the 

 mountain form of the species, and exhibited an unusual 

 number of white spots. 



Mr. J. Jenner Weir also thought the white spots to be 

 exceptional in mountain specimens of C. typJion. 



Mr. Barrett exhibited curious varieties of Melanippe 

 fluctuata, L. 



Mr. Frohawk exhibited living larvae of Melitcza mirinia, 

 Rott., M. cinxia, L., and M. athalia, Rott., Argynnis 

 euphrosyne, L., and A. paphia, L., and stated that one of the 

 A. euphrosyne had hybernated at the end of July, i8gi, and 

 did not commence feeding again until the beginning of April, 

 1892 ; and although the imago should be out by this time, 

 the larva was still feeding, and was 318 days old. The larvae 

 of A. paphia were 282 days old, they having hatched on the 

 8th of August last, and they at once hybernated without 

 eating anything. He had paid particular attention to this 

 point, and had carefully examined them every week, but 

 they did not appear to have moved at all ; they rested ex- 

 posed on the stems of the wild dog violet, and so hybernated. 

 On April 25 an examination of the plants showed four larvae 

 which had moulted, and one of the two exhibited did not 

 moult until four days afterwards ; they were now feeding 

 most rapidly. 



Mr. Frohawk said he understood it was the first time that 

 A. euphrosyne had ever been carried successfully through the 

 winter in confinement, and in reply to a question from Mr. 

 Barrett he stated that it appeared to be a matter of in- 

 difference to the larvae of this species whether the day was 

 sunny or not, as it went up and started feeding each day 

 about ten or eleven, and fed on until five, then going off 

 the plant and resting on the side of the flower-pot ; whereas 

 larvse of M. aurittia and M. cinxia only fed in the sunshine. 



Mr, C. G. Barrett exhibited a long series of examples of 

 Melitcea aurinia, Rott., from various parts of the United 

 Kingdom, in order to illustrate the local variation of the 

 species. Mr. Barrett pointed out that a form known in 

 Scotland, and in Ireland, and some parts of the north-west 

 of England, had the whole of the basal portion filled up with 

 black ; in the south of England a very rich fawn-coloured 

 form occurred ; and in Pembrokeshire a pretty yellow form
