course of the subsequent discussion, agreed with this view. Mr. 

 Porritt said that the melanic variety had occurred to his knowledge 

 for several years in the Bradford district, and that similar varieties, 

 e.g. in A. hetnlaria, showed no signs of depauperization. Mr. Kirkaldy 

 exhibited an example of the rare macropterous form of Vella currens, 

 Fabr., taken at East Grinstead, and one of Cicadctfa montana, Scop., 

 from Brockenhurst. Mr. Burr exhibited a series of grasshoppers with 

 red and blue hind wings of the family ffidipodidse, to show the re- 

 markable variation in colour seen in this group. Ked, blue, and 

 yellow forms are found alike in the same species, the blue being due 

 to the failure of the red pigment, and therefore an incipient albinism, 

 the yellow being a further form of albinism. Mr. Champion com- 

 municated a paper on the Elateridas and Rhipidoceridfe collected by 

 Mr. H. H. Smith at St. Vincent, Grenada, and the Grenadines, and 

 exhibited the specimens. Dr. Forel also communicated a paper on 

 the Formicidffi collected by Mr. Smith in the same islands. — W. F.

April 7th. — Mr. Roland Trinien, F.R.S., President, in the chair. 

 The following Memorandum of an Association for the Protection of 

 Insects in danger of extermination, which had been drawn up by a 

 Committee appointed for the purpose and approved by the Council, 

 was laid before the Society and signed generally by those present : — 

 "We, the undersigned, being desirous of protecting from extermination 

 those rare and local species of Insects which are not injurious to 

 Agriculture nor to Manufactures, do hereby agree, by our own example 

 and by the exercise of our influence over others, to discourage the 

 excessive collection and destruction of those species of Insects which 

 from their peculiar habits are in danger of extermination in the United 

 Kingdom. We further agree to accept for the purposes of this Asso- 

 ciation such list of species in need of protection as shall be drawn up 

 and, if necessary, from time to time amended by the Committee of the 

 Entomological Society of London appointed to that end." The draft 

 of alterations and additions to the Society's Bye-laws, recommended 

 for adoption by the Council, was read for the first time, Mr. 

 McLachlan showed, on behalf of Mr. Gerald Strickland, a magnified 

 photograph of Jh-achi/cerus aptenis, obtained by direct enlargement in 

 the camera, and extremely clear in definition and detail. Mr. Tutt 

 exhibited some of the silk used by Tephrosia historta to cover its ova, 

 and discovered by Dr. Riding. It was contained in a pouch at the 

 extremity of the abdomen in the form of dense bundles about 2 mm. 

 long, and resembling in miniature locks of wavy flaxen hair. Hitherto 

 all such coverings were supposed to consist of scales from the anal 

 segment. Papers were communicated by Prof. Miall, F.R.S., on 

 " The Structure and Life-history of JJmnohia replicata," and by Messrs. 

 Godmau, F.R.S., and Salvin, F.R.S., on " New Species of Central 

 and South American Rhopalocera."
