Am. eyialea, Cram., lecently received from Mr. W. A. Lamborn. 

 The " paper " enclosing the specimen bore the following note: — 



"8 a.m. Half mile [from Oni clearing]; Jan. 30, 1912. 

 Observed flying up and down. It then settled on upper 

 surface of leaf and started to pass its brushes to and fro over 

 its scent-patches, exactly as Amaitris niavius did. Wings 

 were rather over-flexed." 



The latter statement was illustrated by a diagrammatic 

 section which showed that the hind or outer margins of both 

 wings were in contact with the surface of the leaf and thus 

 below the level of the body. The observation was a most 

 interesting confirmation of the conclusions to be inferred 

 from Mr. Lamborn's earlier account of the behaviour of 

 Ain. niavius, L. (Proc. Ent. Soc, 1911, pp. xlvi, xlvii). Together 

 with Mr. Lamborn's specimen, was exhibited a male of Am. 

 egialea in which the brands of both hind wings had been 

 entirely eaten out by ants, and a male of Am. niavius in 

 which the right brand had been partially eaten. The injury 

 was probably inflicted on the dead specimens by house ants. 

 The egialea had been previously exhibited to the Society 

 (Proceedings, 1907, p. x), but in view of this recent observa- 

 tion it was thought well to show it again. 



These observations on the relationship between the anal 

 brushes of male Danainae and the brands on their hind wings, 

 were conBrmatory of Fritz Miiller's remarkable inference, 

 published in the year 1877 ("Butterfly-hunting in many 

 Lands." G. B. Longstaff, 1912, p. 619). 



Dr. F. A. DiXEY said that among Professor Poulton's series 

 of exhibits, that illustrating Dr. Lamborn's valuable observa. 

 tion on Amauris egialea, confirming as it did a previous obser- 

 vation by the same naturalist, had for him a special interest. 

 It was well known that the scent-distributing apparatus in 

 Rhopalocera took the form sometimes of specialised scales 

 scattered broadcast over the surface of the wings, as in many 

 Pierines and Lycaenids ; sometimes of scales or hairs collected 

 into definite patches, as in other Pierines and in the sub- 

 family to which Dr. Lamborn's Amauris belonged. That the 

 patch near the costa of the hind wing in Colias edusa was 

 really a scent-patch, the speaker knew from personal obser-
