Mr. South exhibited and made some remarks upon Noctua 

 f estiva, Hiibn., and its varieties. The Shetland form of the 

 species, to which the varietal name of thiilei (J. tJiules) had 

 been e^iven, was very different from the smaller mountain and 

 moorland form known as var. conflua Treits. ; but there were 

 specimens among the Shetland /"^j-^zm, and others among the 

 Scotch mainland f estiva, which served to connect the two 

 named forms one with the other, and both with the type. 

 At one time, when he had only seen extreme forms from 

 Shetland, he was inclined to consider them distinct from N. 

 f estiva ; but now that he had a more intimate knowledge of 

 the various modifications to which the species is subject, he 

 was quite prepared to accept thulei as a form of N. f estiva. 



Mr. Carrington said that some of the specimens reminded 

 him much of some that he used to take at Rannoch, and 

 which he considered were N. conflua, Treits., these were easily 

 picked out {xox'Cl f estiva^ as the two forms settled on the sugar 

 in different ways. 



Mr. T. D. A. Cockerell exhibited Colias eurytheme, Bdv., 

 forms — (i) amphidusa, Bdv., (2) keewaydin, Edw., (3) ariadne, 

 Edw., (4) eripliyle, Edw,, from the United States. He 

 remarked that these had now been shown to be one species ; 

 it was interesting as showing how species might be made, and 

 how circumstances produced a certain form, which in course 

 of time entomologists called a species. 



Mr. C. Y&x\x\ty^)^\\.&d Agrotis simulans, Hufn.,^. nigricans, 

 L., Acronycta euphorbi(E, Fb., and Sciaphila octoniaciilana, 

 Haw., from Shetland, all showing a tendency to melanism. 



Mr. C. G. Barrett exhibited the specimen of Plusia inoneta, 

 Fab., taken by Mr. Holland at Reading, and expressed an 

 opinion that the species was moving northwards; it was an 

 inhabitant of Eastern and Southern Europe, but within the 

 last few years it had been seen in Belgium and Holland, and 

 there were several records of its being found in this country 

 during the present year: its foodplant was the common 

 monkshood, found in every cottage garden, and it might 

 therefore establish itself here. 



Mr. South added that the first recorded specimen was taken 

 flying over Delphinum in a garden near Dover ; another had 

 been taken at Tunbridge Wells. 



Mr. Tutt, on behalf of Lieutenant Brown, exhibited Agrotis 

 simulans, Hufn., from Portland, where he stated the species 

 had occurred freely ; he called attention to some of the 

 specimens having a well-developed central band, and two of 

 the specimens being of an ochreous colour ; the whole series
