to illustrate the colour variation in the species. In the 

 thirteen specimens shown the colour of the spots of the fore- 

 wings and the area of the hind-wings, other than the extreme 

 margin, graded from the typical rich crimson through shades 

 of terra-cotta and pinkish yellow to a pale clear yellow, 

 the gradations of colour being so gradual that it was almost 

 impossible to distinguish the difference from specimen to 

 specimen, except in the case of the first step from crimson 

 to the darkest of the terra-cotta forms; also an example of 

 the same species of typical colour, in which the four basal 

 spots of each fore-wing were united, forming an irregular 

 elongated patch. 



Mr. Adkin also exhibited a specimen of Pararge megcera 

 in which the usual ocellated spot was absent from the apical 

 portion of the right fore-wing, its place being taken by a 

 minute black dot ; the same variation also showed on the 

 under side. The specimen was taken among a number of others 

 at Folkestone some years ago, and the absence of the spot 

 was not noticed until the insects were removed from the 

 setting-boards ; all the others were typical. 



Mr. Hy. J. Turner exhibited a box of butterflies, chiefly 

 from South America, including a considerable number of 

 more or less hyaline species belonging to numerous genera, 

 particularly Ithomia. 



Messrs. Harrison and Main exhibited : 

 (i) Aplecta nebulosa, bred from larvae taken in Delamere 

 Forest this year. Altogether n per cent, of the very dark 

 and black forms were obtained, and a considerable propor- 

 tion of forms intermediate between these and the ordinary 

 grey 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 last specimen is of the extreme black form, with deep 

 white fringes and margin. For comparison a row of the 

 same species taken in the New Forest was 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. 



(2) Hypsipetes sordidata, series bred from larvae taken at 

 Windermere, Seal Chart, and Delamere, and a few captured 

 specimens from Barmouth. The Windermere insects show 

 considerable variation, from light mottled forms to almost 

 black. 



(3) Xylophasia rurea from the New Forest, Delamere, and 

 Lancashire, and specimens of var. combusta from the two 

 latter localities.
