(much rubbed ; possibly Thalassodes scissaria, Feld.). In this list the new forms are indicated by an asterisk ; these I now proceed to describe :-• PHYSCJENURA PIONE, var. LUCIDA. (Plate XLIII. fig. 1.) Differs from typical P. pione, of which we have a good series, in the larger white area on the upper surface of the primaries, the black internal streak being abbreviated or even sometimes almost obliterated, so that the lobe extending from the white area towards inner margin is of at least double the width : on the under surface the black striae are wider apart, far less numerous, and the yellow ocelli are paler; the three black lines on outer border are not equidistant as in typical P. pione, the two inner ones being nearer together. Expanse of wings, J 39 millim., 2 45. Two males and one female. It is possible that this form may prove constant to locality: it is probably from near Port Songwe, N . W . Nyasa. W e have received typical P. pione only from Zomba and Deep Bay. MYLOTHRIS YULEI, sp. n. (Plate XLIII. fig. 2.) d". Above milky wdiite, slightly tinted with primrose-yellow at the base ; apical border, a very slender marginal line, and a clot at extremity of second median branch black; costal border towards base irrorated with blackish ; secondaries with black marginal clots at extremities of median branches and submedian vein : primaries below golden orange (or cadmium-yellow) to middle of cell; apical area washed diffusediy wdth saffron-yellowish; seven marginal black dots, the last, at extremity of first median branch, very small: secondaries creamy buff, yellower at base, the costal areolet cadmium-yellow ; six black marginal spots, tbe smallest being the fifth from anal angle or that at extremity of radial nervure : body normal. Expanse of wings 51 millim. The female, which I formerly supposed to be a pale variety of M. rueppellli, differs chiefly on tbe upper surface in tbe pale saffron flush at the base of the primaries and the still paler tint at base of secondaries : on the under surface it agrees very nearly with the male. Expanse of wings 59 millim. The female example in the Museum is from Kilima-njaro. PHRISSURA NYASANA, sp. n. (Plate XLIII. fig. 3.) An exact copy of Mylothris rueppellli: differing chiefly in its \ |
