B52 THE entomologist's record. 



continued the discussion. Mr. R. Adkin exhibited a long and in- 

 teresting series of Triphcena comes {orbona), from various parts of the 

 South of England, Yorkshire, Forres, the Isle of Man, the Isle of Lewis, 

 and the North of Ireland. Mr. G. F. Hampscm exhibited a series of 

 varieties oi Flotheia frontalis, Walk., which was the only species in the 

 genus, and confined to Ceylon. He said that the varied forms of this 

 species had been described under twenty-one different names by Walker, 

 Felder, and Moore. Mr. F. Merrifield showed a number of specimens 

 of Selenia ilhisiraria^ of three different stocks, proving that the spring 

 brood of this species, which passed the winter in the pupal stage, was, 

 like the sununer pupa, materially affected in colouring by the tempera- 

 ture to which the pupa had been exposed in its later stages. He 

 thought this fact, coupled with similar results ascertained with respect 

 to the single-brooded Ennomos autiimnaria, indicated that the operating 

 cause was one of wide general a])plication, and that valuable results 

 might be looked for if entomologists would turn their attention to the 

 subject. Capt. Ehves said that in his experience in many parts of the 

 Palaearctic region, in Japan, in the Taunus Mountains, on the north- 

 eastern part of the Mediterranean, in the Canary Islands, and else- 

 where, where there was a combination of heat and moisture, all the 

 commoner species of Lepidoptera occurring in this country attained a 

 larger size and a greater brilliancy of colouring than in colder and drier 

 regions ; and he referred to such species, amongst others, as Pieris 

 hrassiae and Argyntiis paphia. The discussion was continued by Mr. 

 Tacoby, Mr. Fenn, and others. Mr. W. H. B. Fletcher exhibited a long 

 series of Zygcena lonicercB from York, and Zygcena filipendulce from 

 Shoreham, Sussex ; also a series of hybrids obtained by crossing these 

 two species. He stated that the eggs obtained from these hybrids 

 were all infertile. Lord Walsingham jaid this latter fact was extremely 

 interesting. Mr. F. W. Frohawk exhibited a living specimen of an 

 ichneumon which had just emerged from a chrysalis of Papilio tatmiis. 

 Mr. C. J. Gahan exhibited a number of species belonging to the genera 

 Lema and Diabrotica, and read a paper on them, entitled " On mimetic 

 resemblances between species of the Coleopterous genera Lema and 

 Diabrotica" Lord Walsingham, Mr. Jacoby, Colonel Swinhoe, and Mr. 

 Champion took part in the discussion which ensued. — H. Goss and W.
