Show 616 MR. H. Hi DRUCE ON BORNEAN LYC.ENID.E. [June 18, near the costa and becoming more distinct towards the sub-median nervure, on which it broadens into an irregular spot. Hind wing with a similar faint wavy line beyond the middle, starting on the costa and running nearly straight to the second median nervule, where it turns at right angles, and becoming suddenly darker and thicker reaches almost to the anal margin just before the extremity of the abdomen; a large black spot on the lobe crowned wdth metallic green ; a black mark between the submedian nervure and another joining it between the two lower median nervules, both covered with metallic green scales ; a thin black marginal line above the lobe, running into tbe dark band, also dusted wdth metallic green; dark anteciliary lines towards the anal angle. Cilia of fore wdng dark brown, of hind wing pale brown at apex, nearly white towards anal angle. Tails on both surfaces unmarked. Head, thorax, abdomen, and legs concolorous with wings ; tarsi black-spotted. 2 . Differs from the male only by upperside being rich dark brown in place of purplish blue, aud the anal region pure white in place of cream-white. Underside as male, but the pale brown replaced by rich ochreous brown. Expanse, cf l-rV* ? If ^ncn- Kina Balu (Waterstr.). 1 have named this fine species after Dr. Staudinger, whose kindness and generosity have enabled me to describe and figure it here. The types are in his collection. It is not a httle remarkable in that both sexes are nearly alike on the upperside, the female only differing from the male by being brown in place of blue. The third (upper) tail is very slightly developed in the male, but is well marked in the female. B. staudingeri is not closely allied to any other species. BlDUANDA SIMILIS, Sp. n. cf . Upperside-fore wdug dark rich brown ; hind wing shining ca?rulean blue, wdth brown apex and costal margin, two black spots near anal angle; cilia of fore wing brown, of hind wdng w'hite. Underside-fore wdng reddish orange with brown markings; hind wing white, with dark brown markings and bands, reddish along the costal margin and dusted with shining silvery green scales towards the anal angle. Outer margin of fore wing more convex, about equal to that of M. moorei § . Expanse ly^ inch. Borneo. Type Mus. Druce. This butterfly differs from the common Marmessus moorei, Distant, with which it occurs, only by the presence of an additional subcostal nervule, and by the outer margin being more convex. The type specimen, so far as I know, is unique, as after examining a large series of M. moorei I have failed to find another example. This specimen, together with the type of B. imitata, mihi, next described, was formerly in the Rev. R. P. Murray's collection, but unfortunately the precise locality in Borneo is not noted. |
