larval existence ; thus most of the winter wingless females would reach 

 a suitable place to lay their eggs when the time came for them to do 

 so. — J. F. Bird, The Nurtons, Tintern, Monmouth. December 1st, 1905. 



^OCIE TIES. 



South London Entomological and Natural History Society. 

 November 2Srd, 1905. — British Aporia crat^gi. — Mr. J. P. Barrett 

 exhibited a long series of this species, including specimens taken in 

 the New Forest in 1871, and in East Kent in 1901-1905. Aberra- 

 tions. — Mr. J. P. Barrett also exhibited (1) an aberration of Argynjiis' 

 adippe from Three Bridges, the hindwings considerably suffused with 

 black, and the markings thereof running into streaks. (2) An aberra- 

 tion of Melanargia galathea, the black markings of all four wings 

 almost entirely confined to the marginal and submarginal areas. 

 Aberrations of Anthrocera filipendul^. — ^Mr. K. Adkin exhibited a 

 series of this species to illustrate the gradual change in the colour 

 from the typical rich crimson [filipendulae) through shades of terra- 

 cotta (ab. interviedia) and orange (ab. aurantia), to a pale clear yellow 

 (ab. iiava) ; also an example in which the four basal spots were united 

 into an irregular elongated patch (ab. bipunctata). [These forms are 

 all described in Tutt's Nat. Hist, of the British Lepidoptera, i., pp. 

 508-520] . Aberration of Pararge meg^ra. — Mr. Adkin also showed 

 a Pararge megaera in which the apical ocellated spot was absent from 

 the right forewing, there being only a minute black dot. It was also 

 without the ocellus on the underside. Aberrations of Aplecta 

 NEBULOSA. — Messrs. A. Harrison and Main exhibited a series of Aplecta 

 ■nebulosa bred from larvfe taken in Delamere Forest, in 1905. 

 Altogether 11 per cent, of the black and very dark forms were 

 obtained, and a considerable proportion of forms intermediate between 

 these and the ordinary Delamere form. The difference between the 

 two extremes is very great, and the gap between them is bridged over by 

 an almost regularly graded series of intermediates. The most extreme 

 specimen is of the wholly black form with white fringe and margin. 

 For comparison a few taken in the New Forest were shown. From 

 the Delamere larvae 18 per cent, of ichneumons were bred, whilst in 

 1904, from larvae taken on the same ground, no ichneumons were 

 obtained. Aberrations of Hypsipetes sordidata. — They also exhibited 

 a series of this species bred from larvaB taken at Windermere, Seal 

 Chart, and Delamere, with a few taken on the wing at Barmouth. 

 The Windermere insects show a considerable variation, ranging from 

 light mottled forms to almost black. Twenty-two specimens bred from 

 Windermere larvae gave 4 almost black (forewings), and the remaining 

 18 are graded from very dark to light mottled, difficult to classify 

 and give proportions. Aberrations of Xylophasia rurea. — Also a 

 series of this insect from the New Forest, Delamere, and Simonswood 

 Moss, Lancashire, with specimens of ab. combusta from the two latter 

 localities. Agrotis exclamationis ab. picea. — A black aberration of 

 this species from SimonsAvood Moss, Lancashire. Aberrations of 

 Xylophasia monoglypha. — A varied series from Barmouth and Crosby 

 sandhills, showing one very dark aberration from the latter locality. 

 Cymatophora DUPLAEis AB. oBscuRA. — Also a iiielanic series of C. duplaris 

 from Simonswood Moss, where this species, so far as the experience of the
