[March, 1889. 



South America, which were quite unknown over a vast extent of the intermediate 

 latitudes, but it should be borne in mind that there was in the American continents 

 an almost continuous chain of mountains from the Arctic Ocean to the Straits of 

 Magellan, which might have formed a connected temperate region, by which the 

 migration of species from the North to the South was effected, at a time when the 

 temperature of the earth was different to that which now obtains. 



Mr. Carrington, parasites from larva of Acronycta alni, L. Mr. Tugwell, on 

 behalf of Mr. Porritt, two very dark specimens of Boarmia repandata, L. 



Observations were made upon a reported case of stridulation by a species of 

 Vanessa, and a discussion ensued. — H. W. Barker, Son. Sec. 



Entomological Society of London: February 6th, 1889. — The Eight Hon. 

 Lord Walsingham, M.A., F.E.S., President, in the Chair. 



The President announced that he had nominated Mr. H. J. Elwes, F.L.S., 

 Mr. F. Du Cane Godman, F.B.S., and Dr. Sharp, F.L.S., Vice-Presidents for the 

 session 1889— SO. 



The Eev. F. D. Morrice, M.A., of Eugby; Mr. A. Eobinson, B.A., of Brettanby 

 Manor, near Darlington ; and Mr. H. Burns, of Fulham, S.W., were elected Fellows. 



Lord Walsingham exhibited a larva of Lophostethus Dumolini, Gruer., sent to 

 him by Mr. Gilbert Carter, from Bathurst, West Coast of Africa. 



Mr. G. T. Porritt, exhibited several melanic specimens of Boarmia repandata 

 from Huddersfield, and, for comparison, two specimens from the Hebrides. Mr. 

 McLachlan remarked that melanism appeared to be more prevalent in Yorkshire and 

 the north midlands than in the more northern latitudes of the United Kingdom. 



Mr. Elwes read a paper " On the genus Erebia, and its geographical distribu- 

 tion." The author, after referring to the number of species and named varieties, 

 many of which appeared to be inconstant as local forms, made some remarks on 

 the nomenclature of the genus, and suggested that a better system of classification 

 might be arrived at by anatomical investigation. It was stated that little was known 

 of the early stages and life-history of species of this genus, the geographical distri- 

 bution of which was Alpine rather than Arctic. The author remarked that it was 

 curious that there was no species peculiar to the Caucasus, and that no species 

 occurred in the Himalayas, where the genus is replaced by Callerebia; that none 

 were found in the Himalo-Chinese Subregion, and none in the Eastern United States 

 of America. He also called attention to the similarity of the species in Colorado 

 and North-West America to the European species. Lord Walsingham, Mr. 

 Waterhouse, Mr. O. Janson, Mr. McLachlan, Dr. Sharp, and Mr. Jenner Weir took 

 part in the discussion which ensued. 



Mr. W. Warren read a paper " On the Pyralidina collected in 1874 and 1875 

 by Dr. J. W. H. Trail in the Basin of the Amazons." 



Mr. C. J. Gahan read a paper entitled " Descriptions of new or little-known 

 species of Glenea in the Collection of the British Museum." 



Mr. J. S. Baly communicated a paper entitled "Notes on Aulacophora and allied 

 genera." — II. Goss, Hon. Secretary.
