Mr. Austin, of Highbury, was elected a member. 



Mr. E. C. Goulton exhibited a bred series of Hypsipetes 

 sordidata (elutata) from various Surrey localities ; the larvae 

 were fed on nut and willow ; and two males of Cosmotriche 

 botatoria captured at Wicken, and wholly of the very light 

 female coloration. 



Mr. A. J. Willsdon exhibited a gynandrous example of 

 Crocallis elinguaria, from Manor Park. 



Messrs. A. Harrison and H. Main exhibited Odontopera 

 bidentata. A melanic series bred this year from black 

 parents from Horbury, Yorkshire ; and another bred series 

 from rather dark parents from the same locality. 



The brood from the black parents were almost all black, 

 there were a few less dark specimens, but unfortunately they 

 were not able to give the exact percentage. No black 

 specimens were obtained from the dark parents. 



Also a series bred from a very light female taken at 

 Wisley in 1906,011 one of the Society's excursions; and 

 various series from Epping Forest, New Forest, N. Corn- 

 wall, Wallasey, Delamere Forest, Liverpool and Durham, 

 a few being captured specimens, but most of them bred 

 from collected larvae.; together with a varied series from 

 the Isle of Lewis, which have been exhibited here on a 

 former occasion. 



Pieris napi, var. bryonice : four broods, bred from specimens 

 captured in July, 1906, on the Kleine Scheidegg Pass, 

 Switzerland. The females of all the broods exhibited a 

 considerable amount of variation, especially in broods B. 

 and C. The majority had a yellow or brownish-yellow 

 ground colour, with the black marking boldly defined. 

 Some had no yellow in the ground colour, and in these the 

 black markings varied very much. One specimen in brood B 

 had almost obscured grey scales, similar to those at the 

 base of the wings in the females of the English napi, being 

 spread over the whole surface of the primaries, and giving 

 an almost unicolorous effect. A specimen in brood C was 

 very similar to some of the British examples. 



Variation in the males consists mainly in the presence or 

 absence of the central spot in the fore-wings, and in the 

 quantity of dark scales along the veins on the under-surfaces. 



Bryonice is single-brooded, appearing in July in the 

 locality in which the parents of these broods were taken. 

 As regards size, they are much larger than our spring form, 

 and fully up to the average of the summer emergence ; but 

 as regards markings, especially on the under surfaces, they
