(4) The most striking effect is noticeable in certain species 

 of Andrena {A. hbialis and A. chrijsosceles) in whicli tlae (J 

 normally has a yellow clypeus and the $ a black one. 

 Stylopisation may lead in these cases to a $ assuming a yellow 

 clypeus as in the 3, and the S may lose the yellow and acquire 

 a partially black clypeus. 



South European Butterflies.— Mr. E. B. Ashby ex- 

 hibited some South European butterflies, chiefly from the 

 south of France, including Melanargia galathea var. procida 

 and ab. leucomelas, another aberrant Melanargia from Barcelona 

 showing characters both of M. galathea and M. lachesis, 

 Polyommatus admetus, var. rippartii, from Clelles where it 

 had been taken this year by the exhibitor and Dr. Keynes, 

 the most northerly locality recorded, and P. meleager with 

 blue ? from Digne, whereas all the ? ? from St. Martin -Vesubie 

 were of the brown form ab. steeveni. 



Mr. Rowland-Brown remarked that as a rule the ? ? of 

 P. meleager were brown at higher elevations, whereas at Digne 

 the two forms were about equally numerous. 



The Rev. G. Wheeler observed that farther south at 

 Roccaraso in the Abruzzi he had found only the blue i' ^^, at 

 a height of over 4000 ft. 



Xanthic Psilura monacha. — Mr. Rippon exhibited a 

 variety of P. monacha, which, as far as he had been able to 

 ascertain, had not been previously recorded. The variation 

 consists in the body being banded with black and yellow 

 instead of black and crimson. The examples exhibited were 

 bred by him this year from a strain that he had had going for 

 two or three years with the object of increasing the black 

 wing coloration. He judged that possibly one-third of one 

 brood were of the yellow variety, but unfortunately was unable 

 to give any exact figures as he did not observe the yellow form 

 till most of the brood liad emerged. 



Triphaena Fimbria. — Mr. Rippon also exhibited five 

 specimens of Triphaena fimhria, bred from Pamber Forest 

 larvae, one of which showed a tendency to melanism even in 

 the hind- wings, and the others showing some modification of 

 the two usual forms. 

 South Russian Heteroceba. — Mr. A. H, Jones exhibited
