from East Afiica, phanara and ekinkei from West Africa, 

 kahldeni and homeyeri from West Africa. This exhibit con- 

 firmed the result of Mr. G. F. Leigh's breeding experiment 

 mentioned by Professor E. B. Poulton at the last meeting. 



•Melit^eas of the Athalia group. — The Rev. G. Wheeler 

 exhibited a pair of Melitxa dictynna, var. dictynno'ides, Horm., 

 received from Herr Hormnzaki the previous day, and exactly 

 corresponding with his description in "Iris," xi, p. 2 (1898). 

 These are therefore absolutely authentic. They ai-e the con- 

 verse of M. hritomartis, having the upper side of M. dictynna 

 but the under much nearer to M. parthenie. The form is 

 usually described as a var. of M. aurelia, Nick., but this 

 seems unlikely, as almost typical aurelia — a specimen of 

 which was exhibited — are found at the same place, Mt. 

 Cecina, near Czernowitz, Bukowina. It may probably be a 

 good species. A pair of M. athalia from the same locality 

 was also shown, somewhat small and light in ground colour, 

 but rather heavily marked. 



Experiments in crossing British Pieris napi with Swiss 

 PiERis NAPI, VAR. BRYONIA. — Mr. A. Harrison and Mr. H. 

 Main exhibited a number of examples to illustrate the result 

 of breeding experiments with British Pieris napi and Swiss 

 P. napi, var. bryonise. Ova were obtained from bryonise, taken 

 in July 1906, on the Kleine Scheidegg Pass, and from these 

 a series of imagines was bred in the spring of 1907. All the 

 females were the var. bryoniie. Although of course the form 

 known as bryonix is confined to the female, it will be con- 

 venient to refer to the males also as bryonise. Some of these 

 males were paired with English ?zapt from Cornwall, and 195 

 insects were bred as a result of these pairings, emerging as 

 follows : — 



In summer of 1907 . 

 In spring of 1908 .

Most of these insects were quite typical najn, only one
