Show 394 MR. H. J. ELWES O N SOME [May 6, b". With marginal bands present. White hind wings. 15, BIZONE ARIADNE, Leech, MS. This is a good species, distinguished from signa by marginal band and shape of the second and third bands ; in the male there is a pink spot on the costa above the black spot, which is separated by the fold from the pink band. It has been found in Central China, at Changyang, by Mr. Pratt. V". Red hind wings. 16. BIZONE PRATTI, n. sp. This was sent to m e by Mr. Leech under the name of B. san-guinea, Brem., but it is quite distinct from what I take to be that species, which is described further on. It is like B. ariadne, but differs in having the hind wings and abdomen bright pink as in B. bianca. There are three black spots in both sexes, but in the male the outer one is placed on the third bar instead of within it. As this species will doubtless be figured by Mr. Leech, I will not describe it more particularly. It was taken by Mr. and Mrs. Pratt at Changyang and Ichang in June 1888. Next we have a group of five species with four fawn-coloured bands (except in B. sikkimensis, which has only three), all, so far as I know, confined to the Himalayan region. They are all nearly allied but, as I believe, quite distinct. I have been obliged to name no less than three of them, which I should not have ventured to do if I had not examples of both sexes in good condition of every species. c. 4 yellow bands. c1. Pink body and pale pink hind wings. 17. B I Z O N E A R A M A , Moore, Cat. E. I. C. ii. p. 306, t. 7 a. fig. 10, $. A distinct species, which seems rare wherever found. The male, which is undescribed, I have only seen in Dr. Staudinger's collection. The middle spot in the male takes the form of a short bar, as though two spots were united. The outer spot is placed, as in B. pratti, rather outside the third band, which is broken by the fold, and appears as a spot on the costa. I have females from Kulu and Sikkim in m y collection, and there are others from Khasia in the British Museum. c2. White body and hind wings ; hind wings with a dark lunule. 18. B I Z O N E D O H E R T Y I , n. sp. (Plate XXXII. fig. 4, $ .) $ 2 • White, with pale yellow bands on the thorax and tegulae. Four pale yellow bands across the wings, of which the first does not extend to the hind margin, the second and third irregular. In |
