the pupal skins. These young rufa ^ ^ were exhibited 
mounted on card. 
Nest No. 2 consisted of a mixed nest of Formica rufa and 
F. fusca. This nest which was very small but built of F. 
rifa materials, was dug up in Parkhurst Forest on August 
21st, 1910. It was found to contain 1 rufa $, some rufa 
5 ^, and many fusca 5 ? > ^ number of cocoons—these 
as they hatched proving to be rufa 5 5- It is therefore clear 
that this o'ufa $ must have founded her nest in a fusca nest- 
The fusca were underground with the rufa ? and cocoons, 
but no fusca $ was present. 
PlERIDAE FROM FRANCE AND ItALY. —Mr. A. H. JoNES 
showed a series of Pieris manni, males only, from the valleys 
of the lower slopes of Mont Canigou, near Veimet-les-Bains, 
taken at the end of June last, with examples of P. rapae, 
and P. ergane from Italy for comparison. 
Mr. P. J, Barraud brought for exhibition a case containing 
Pieridae from the neighbourhood of Formia, Central Italy, 
including Pieris rapae, L., and var. metra, Stephens ; Pieris 
manni, Mayer, and var. rossii, Stefanelli, and ab. erganoides, 
Stefanelli; and Pieris ergane, Hiibn. With these he showed 
also enlarged photographs of male and female examples of 
the summer forms of the above-named species to illustrate 
the difference in the character of the markings and shape of 
the wing; and enlarged photographs of the male genitalia of 
each, exhibiting the difference in the shape of the clasper. 
Butterflies from the Abruzzi. —The Eev. G. Wheeler 
gave an account of an entomological excursion made by him 
in the Abruzzi, and exhibited two drawers containing speci¬ 
mens taken at Assergi, Sulmona, Aquila, Roccaraso, Palena, 
Scanno, and Villalago; and a few also from Subiaco in the 
Latian Apennines. Pieris ergane was found to be somewhat 
widely distidbuted, having been taken at Sulmona, 1,300 feet; 
above Subiaco, about 2,000 feet; and at Roccaraso, over 
4,000 feet. There was also a series of very strongly mai'ked 
Hesperia carlinae var. cirsii, some of Avhicli approached somewhat 
closely to H. cynarae. Polyommatus eros, of a much deeper blue 
than is usual in the Alps was abundant at and above 4,000 feet, 
i.e, nearly 2,000 feet lower than is normal in the Alps; other
