4. Lyonetia clerkella, long series bred from cocoons found at 

 Reigate on cherry by Dr. T. A. Chapman, which had not 

 produced a single typical example. The specimens are dark, 

 and some nearly black, with the markings very indistinct 

 and suffused. 



Mr. C. P. Pickett exhibited a large number of aberrations 

 of British Lycasnidse, Mimas tilicc and Angerona pritnaria, 

 including — 



Polyommatns {LyccEua) corydon — (i) " dwarfs," size of 

 Ctipido {LyccEua) minima ; (2) unusually large, measuring 24- 

 inches in expanse ; (3) nearly white cilia ; (4) deep suffused 

 black submarginal bands ; (5) with P. adonis coloration of 

 male ; (6) females perfectly blue ; (7) females, one or more 

 wings shot with blue; (8) males and females, absence of 

 ocelli ; (9) males and females with large ocelli ; (10) with 

 ocelli united into streaks; (11) various shades of ground 

 colour on undersides; (12) females assuming ground colour 

 of typical males ; (13) female very light brown ; (14) 

 females, very conspicuous spots on margin of hind wings. 



P. hellargns, showing similar lines of variation to P. corydon, 

 and also (i) having coloration of P. corydon; (2) having 

 coloration of P. icarus ; (3) having shape of wings of 

 Cyaniris argioliis ; (4) females, lead-coloured. 



P. astrarche — (ij dwarfs ; (2) underside ground almost 

 white ; (3) fore-wings with spots joined. 



Cyaniris [Lyccena) argiolus, female with unusually deep 

 bands. 



Cnpido {Lyccena) minima, right underside with spots obso- 

 lete, the left normal. 



Mimas {Smerinthus) tilicB, all bred from dug pupae — (i) males 

 of female coloration ; (2) dark and light forms ; (3) well- 

 developed bands ; (4) with band partially or wholly sup- 

 pressed ; (5) with asymmetrical markings; (6) females with 

 male coloration ; (7) female measuring 3I inches in expanse ; 

 (8) almost black hind wings. 



Angerona prunaria, the results of four years' interbreeding 

 and selection between a dark male taken at Raindean 

 Wood, Folkestone, and a light-banded female from Ching- 

 ford. Those exhibited ranged from plain orange males and 

 females to deep chocolate-banded forms of both sexes. The 

 chief aberrations were — (i) exceptionally dark ; (2) with 

 asymmetrical markings ; (3) very slightly banded ; (4) por- 

 tions of the band suppressed ; (5) very deeply mottled.
