Show 1895.] THE COUNTRY WEST OF LAKE NYASA. 629 disc of wing rosy blood-red, wdth diffused ochreous external edge; external border jet-black, with white spots on the fringe at extremity of internervular folds : body blackish ; eyes coppery bronze, varied with blue-black ; head deep brown, wdth two white spots before and behind; pterygodes and front of thorax bronze-green, sides of thorax clothed with copper-brown hair; base of abdomen hairy, shot with blue and green. Below differing from E. zaddachii in the regular creamy bauds of the primaries, the inner edge of the subapical band slightly concave, instead of elbowed, the lower half of the first band not incised internally; a large yellow patch filling the end of the cell of secondaries, and a still larger patch or abbreviated band beyond the cell, commencing at subcostal vein in an elongated subpyriform patch, the inferior portion of which is occupied by an acutely angled, almost 1-shaped streak; from the first subcostal to the third median nervule the band is of a clearer yellow and gradually widens, its inner edge being unequally trisinuated and not accompanied by black spots : the submarginal spots are uniformly smaller than in E. zaddachii, but the remaining characters are similar. Expanse of wings 80 millim. cf, Lumpi Eiver, Nyika, west of Lake Nyasa, Sept. 19th, 1893. " Cream, velvet, and crimson" (R. ft), 4. METACRENIS ROSA. 2 . Crenis rosa, Hewitson, Ent Month.

It is of swift flight, and very difficult to catch, as it perches on trees, high up, out of one's reach as a rule. I at first took this insect for another which I got at Mweru, and which M r . Butler was kind enough to name after me-viz., Crenis crawshayi; but, on closer examination, I see it is not the same except in general tone of colour." 5. ARGYNNIS SMARAGDIFERA, sp. n. (Plate XXXV. figs. 1, 2.) d. Intermediate in character between A. lathonia and A. euphrosyne ; size, form, and general pattern of the upper surface of the latter, but the base of the wdngs wdth the basal area broadly greyish green, the marginal spots of the primaries pale yellowdsh towards apex, and the centre of the secondaries spotted almost as in A. lathonia : wings below perfectly intermediate between these two very distinct species, the ground-colour of the apex of the primaries being characteristic of A. euphrosyne, clear yellow with similar ferruginous patches; the greater portion of the primaries, however, is of a dull tawny hue ; the subbasal D-sbaped black marking in the |
