Show 596 MR. H. H. DRUCE ON BORNEAN LYCEENIDEE. [JunelS , ARRHENOTHRIX, de Nicev. It is with much pleasure that I am able to add another species to this interesting genus ; I have carefully examined the specimen and find that it agrees exactly in venation with A. penicilligera, de Nicev.,-thus proving that Deccctlana and Arrhenothrix are found flying together. ARRHENOTHRIX LOWII, sp. n. (Plate XXXIII. fig. 2 d •) d. Upperside much like A. penicilligera, but of a much duller and more purple shade of blue ; the apex and outer margin of fore wing considerably less broadly black. The outer margins of both wings, especially that of the hind wdng, much more convex than in A. penicilligera. Tbe whitish tuft of hairs covering the brown patch on the fore wing as in A. penicilligera. Underside differs from that species iu the more russet-brown colour and by the complete absence of the conspicuous white band which crosses both wings. The lobe also is smaller and the tails shorter and more slender, especially that one on the submedian nervure, which is scarcely half the length of the corresponding tail on A. penicilligera. Expanse 1| inch. Labuan (Low). The type of this species, and the only specimen known to me, is in Messrs. Godman and Salvin's collection. A glance at the underside will at once distinguish this from its congener. PRATAPA, Moore. PRATAPA LUCIDUS, sp. n. (Plate XXXIII. fig. 3 c?') Iolaus cippus, Druce, P. Z. S. 1873, p. 351. d. Closely allied to P. cippus, Fab. Differs on the underside by the entire absence of the linear band, excepting over the orange patch at the anal angle of the hind wing, wdiere it is present but very narrow. The black spots are smaller, and the orange patch is darker and not divided as in P. cippus. Expanse as P. cippus. Labuan (Low and Waterstr.). Type Mus. G. & S. The specimens before me show no variation. Messrs. Godman and Salvin's collection also contains this species from Sumatra. PRATAPA SANNIO, sp. n. (Plate XXXIII. fig. 15 d •) ci1. Allied to P. anysis, Hew. Upperside much the same, but with the shining surface on the hind wdng extending further down towards the apex. Underside differs from P. anysis by the band which crosses both wings being narrow and more sordid white, by the shining surface along the inner margin of the fore wdng being blacker, and by tbe broken black line in the hind wing being more curved outwardly towards the apex and more inclined to be semi- |
