360 THE ENTOMOLOGIST. 



male and female specimen of Anisolabis colossea, Dohrn., from New 

 South Wales — the largest known earwig in the world. 



November 7th, 1900. — The President in the chair. — Dr. John 

 Cotton, of 126, Prescot Road, St. Helen's; Mr. George H. Howes, of 

 Spey Street, Invercargill, New Zealand ; the Hon. F. M. Mackwood, 

 M.I.C., of Colombo, Ceylon ; Mr. William J. Rainbow, of the Australian 

 Museum, Sydney; and Mr, Percy Charles Reid, of Feering Bury, Kel- 

 vedon, Essex, were elected Fellows of the Society. — Mr, George S. 

 Saunders exhibited specimens, from Devonshire, of Pieris rapce and 

 Plusia gamma caught by the proboscis in flowers of Araujia albens, 

 Don, a climbing plant of the natural order AsclejnadacecB ; and ex- 

 plained the nature of the mechanism by which the insects were 

 entrapped by the flowers. He also showed specimens of the " bede- 

 guar " gall formed apparently on the " hips," or fruit, of Piosa canina, 

 the formation of the galls on the hips being considered unusual. They 

 were taken from a small briar about four feet high, having more than 

 thirty of these galls, which was growing on the top of the North 

 Downs near Reigate. Mr. Gahau remarked that the capture of insects 

 by Araujia albens had recently been investigated in France by MM. 

 Mai'chand and Bonjour, whose account appeared in the ' Bulletin de la 

 Soc. des Sciences Nat. de I'Ouest de la France ' for 1899. These 

 authors concluded that insects were captured only by immature flowers, 

 the anther-wings, in the cleft between which the proboscis of the 

 insect is caught, being at that time stiff and resistant ; but when the 

 flowers are ripe the anther-wings become less rigid and do not offer 

 sufficient resistance to the withdrawal of the proboscis, which carries 

 with it the pollinia ready to be transferred to the stigma of the next 

 flower visited by the insect. — Mr. Tutt exhibited, for the Rev. Mr. 

 Burrows, a large series of Epunda luudenta from Mucking, in Essex, 

 and made remarks upon several interesting variations included in the 

 series. — Mr, W. J. Kaye exhibited Hijdrocampa stagmdis, var., with 

 examples of the typical form for comparison ; the variety differed in 

 having the basal line nearly obsolete, the sub-median double line much 

 strengthened internally and reduced externally, and the cross-band 

 connecting the sub-median and post-median bands almost entirely 

 obliterated. — Mr. F. Merrifield exhibited a variety of Argynnis dia 

 taken with a few examples of the ordinary form at Ilanz, in the Vorder 

 Rhein Valley, early in September last, when what was, he believed, a 

 third brood of this species was abundant ; the variety was much 

 blackened on the basal half of all the wings. — Canon Fowler exhibited 

 a specimen of Orochures angustatus, Erichs., a Staphylinid beetle new 

 to the British list, taken at Leverstock Green, Herts, by Mr, Albert 

 Piffard. — The Rev, F, D. Morice mentioned as a fact of some interest 

 that in a nest of Formica sangidnea at Weybridge, in which he found 

 males and workers of that species, he found also males and females as 

 well as workers of the slave-ant Formica fusca, an experience samewhat 

 different to that of Huber and Darwin, who stated that workers only of 

 the slave-species were found in the nests of sangidnea. — The Secretary 

 read " Some notes on variations oiZeritis thysbe, Linn.," communicated 

 by Mr. H. L. L. Feltham, of Cape Town, and, on the latter's behalf, 

 exhibited one female and two male specimens of one of the rare forms 

 referred to in the paper. This form was originally noticed by Mr,
