Show 854 ON LEPIDOPTERA F R O M NYASA-LAND. [Nov. 17, broader wings, the pretence of the apical subcostal bifurcation, and in the form and greater intensity of the apical marginal black spots : wings above milk-white ; primaries with the basal third bright cadmium-yellow bordered wdth gamboge; costal border irrorated with black; apical border narrowly pearl-grey, the apical furca and a series of triangular spots terminating the nervures intense black : secondaries faintly tinted with yellow at the base ; a marginal series of eight intensely black spots: body normal. Primaries below white, with extreme costal margin and dots at extremities of nervures black; base almost to end of cell brilliant orange edged with yellow ; apical border creamy buff: secondaries creamy buff, palest over end of cell, base suffused with orange, the costal areole brilliant orange, external border washed with deep buff; black spots as above: body whitish. Expanse of wings 64 millim. Two males. The following Heterocera are new:- LlPARIDjE. A N T I P H E L L A ATRINOTATA, sp. n. (Plate XLIII. fig. 5.) Pearl-white, wings semitransparent; primaries with three subapical spots in a slightly curved series parallel to outer margin and two spots placed obliquely near external angle, all blackish and very small; costal margin also black, very distinctly so at basal third : antennae pale testaceous; body of similar colouring, but densely irrorated, rather than clothed, with white scales: under surface as above. Expanse of wings 34 millim. One male. NYCTEMERIDJE. PH^EGORISTA ZEBRA, sp. n. (Plate XLIII. fig. 4.) o". Like P. similis, Walk. (= helcitoides, Dewitz), but the subapical patch ou the black area of primaries broad and almost wholly ochreous as in P. formosa, the spot towards external angle also ochreous ; secondaries orange-vermilion, with the usual black border and white-chequered fringe: body as in P. slmllls. Expanse of wings 71 millim. One male. NOCTUIDAE. E O D I N A JOHNSTONI, sp. n. (Plate XLIII. fig. 6.) Close to F. alblclncta, but with the primaries more closely resembling those of F. postmaculata in pattern, the wing being crossed as in that species by an oblique buff band ending at external angle in a greyish lobe ; outer margin also buff; fringe greyish. Expanse of wings 17 millim. One rather poor example. This is doubtless the African representative of the Ceylonese F. postmaculata, from which the more buff-tinted markings of the |
