Show 86 MR. R. TRIMEN ON BUTTERFLIES [Jan. 20, A female from the Okavango River is the largest I have yet measured, expanding 1 in. 7 lin. The species is widely distributed over extra-tropical South Africa, and is also recorded from Kinsembo, a little to the N. of Ambriz in Angola. 64. IOLAUS PALLENE (Wallengr.). Myrina pallene, Wallengr. K. Sv. Vet.-Akad. Handl. 1857, Lep. Rhop. Caffr. p. 36. Okavango River (December). One male example. This species, so isolated in colour and marking, seems to be remarkably rare, although known to occur at widely-remote spots, such as Lakes Nyanza and Nyassa in tropical, and Swaziland and Natal in extra-tropical South Africa. From the latter region of the continent I have seen but one individual, but have been authentically informed of the occurrence of five others. Genus APHNCEUS, Hiibn. 65. A P H N C E U S ERIKSSONI, n. sp. (Plate IX. fig. 15 2 •) 2 • Exp. al. 1 in. 7 lin. Dull brownish red, with a common terminal hind-marginal fuscous line; cilia short, whitish. Fore wing : just at extremity of discoidal cell a good-sized rather iudistinct quadrate ochre-yellow spot; a little beyond it a transverse series of five smaller spots of the same colour, lying between subcostal nervure and first median nervule, of which the third (between lower radial and third median nervules) is nearer hind margin than the rest, and the fifth (lowest) is smallest and most indistinct. Hind wing : traces of three very indistinct ochre-yellow spots, one at extremity of discoidal cell, and two (very small) beyond it; anal-angular portion much elongated and produced, with a very prominent broad terminal lobe, fuscous, with bronzy-greenish scales; at extremity of submedian nervure a moderately-long rather stout tail, of the ground-colour. [Tail on 1st median nervule wanting, but probably present in uninjured examples.] UNDERSIDE.-Brownish ochre-yellow, with good-sized, rounded, thinly ferruginous-brown-edged ochre-yellow spots ; in both wings, a terminal discocellular spot, and an irregular discal series of contiguous spots, also a series of separate spots along hind margin. Fore wing : in discoidal cell two spots, one subbasal, the other median ; inner-marginal border dull pale yellowish ; six spots in discal series, of which the third (between lower radial and 3rd median nervules) is beyond, and the sixth (imperfect, and below 1st median nervule) before, the rest; seven spots in hind-marginal series. Hind wing: a subbasal series of four circular spots, of which the 2nd is in discoidal cell, and the 3rd (between 1st median nervule and submedian nervure) is considerably beyond the rest; nine spots in discal series, of which the 2nd, 3rd, 4th, and 8th are more or less beyond the rest; in hind-marginal series six separate spots, succeeded (below 1st median nervule) by three confluent into one; some metallic-greenish scales on extremity of anal-angular lobe, preceded (below submedian nervure) by a small dull crimson spot. |
