103 THE ENTOMOLOOist. 



attentiou to the subject. Capt. Elwes said that in his experience in many 

 parts of the Palsearctic region, in Japan, in the Taunus Mountains, in the 

 Canary Islands, and elsewhere, 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 hrassiccB and Argynnis papliia. The discussion was continued by 

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

 long series of Zygcena lonicerce 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 said 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 Pupilio taunus. Mr. C. J. Gahan 

 exhibited a number of species belonging to the genera Lema and Diahrotica, 

 and read a paper on them, entitled " On mimetic resemblances between 

 species of the Coleopterous genera Lema and Diahrotica^ Lord Walsing- 

 ham, Mr. Jacoby, Colonel Swinhoe, and Mr. Champion took part in the 

 discussion which ensued. — H. Goss and W. W. Fowler, Hon. Sees.

 — February 2Qth, 1891. Mr. W. H. Tugwell, President, in the chair. Mr. 

 K. J. Anderson, of Suez, was elected a member. Mr. Adye exhibited an 

 unusually dark form of Notodonta camelina, L., with other forms of the 

 species. Mr. H. Moore, Erebus odora from South America. Mr. Turner, 

 Melanippe fluctuata, L., taken at Brockley; the specimens showed con- 

 siderable variation. Mr. Cockerell, Heliothis armigera, var. umbrosa, Grote, 

 from Wet Mountain Valley, Colorado, larger than the type, the upper wings 

 more or less olivaceous above, the under wings almost without markings 

 below. Mr. Cockerell made some remarks on Leucania unipuncta, which 

 he stated was a great scourge in America, and was there known as the 

 army worm. Mr. R. Adkin exhibited long series of the species of the 

 genus Triphcena, Och., from many localities in the British Islands, together 

 with continental series of some of the species for comparison, and read notes 

 dealing with the geographical distribution and general and local variation of 

 the species exhibited. In dealing with T. comes he pointed out Hiibner's 

 typical form, the varieties adseqna and j^^'osequa of Treitschke, and curtisii 

 of Newman, also Hiibner's consequa, which he considered should be regarded 

 as a form of this species rather than of orhona, Hufn., to which it had 

 hitherto been referred, and supported his contention by specimens known 

 to be forms of comes, Hb., which agreed with Hiibner's figure of consequa. 

 He also described the distinguishing characters of these varieties, and gave 

 notes on the nomenclature of the species. Mr. C. Fenn exhibited examples 

 of the genus Triphatna from Forres. Mr. McArthur, T. comes from the 

 Isle of Lewis, and T.ianthma from Northumberland. Mr. Turner, T.pro- 

 nuba from Brockley, Kent. Mr. South and Mr. Tugwell also showed 

 varieties of many species of the genus, and a discussion ensued, Messrs. 

 South, Fenn, Tugwell, Adkin, and others taking part. Mr. E. Step 

 exhibited an hybernating specimen of Vespa germanica[iema.\e); Mr. Billups 

 remarked that he had taken this species as early as the 17th January in a 

 previous year.
