The single example is rather darker than the specimens in the Museum series, but differs in no other respect. 55. CRENIS CRAWSHAYI, sp. n. (Plate LX. fig. 5.) Greyish blue, the whole centre suffused with rosy lavender; the base and costa of primaries, and the body above, slightly greenish ; wings with slightly sinuated black outer margins and delicate white fringes ; veins black externally; disk of wings crossed by three series of black spots beyond the middle, the innermost series angulated and very oblique on the primaries, almost obliterated on the secondaries, the first two spots of the series cuneiform, the others rounded; second series double towards costa, the first three spots being preceded by elongate blackish streaks ; a minute white dash between the first pair, which would otherwise be lost in the black veins, of which they form a mere thickening; the spot on interno-median area divided; submarginal series formed of more or less lunate spots ; costa of secondaries and hairs on abdominal area somewhat brownish. Underside most like that of C. rosa, but deeper in colour, the primaries with two complete series of black spots towards outer margin, the first of the inner series and the first two of the outer series enclosed by a pale silvery blue apical costal streak, the three following pairs united by longitudinal streaks of the same colour, the fourth pair by a few blue scales ; all the spots of the outer series united to pale blue marginal spots ; extreme margin blackish, with white fringe : secondaries having the general aspect of those of G. rosa, but entirely different in details ; costa broadly pale blue, -with a black interrupted longitudinal Une above the costal vein ; a black spot below it at centre of costa and a cuneiform orange spot enclosing the precostal veinlet; a broad almost triangular blue patch nearly covering the cell, within which are black irregular characters similar to those of Argynnis or Euthalia; a blue streak runs down the abdominal border, and a second, enclosing the submedian vein, unites with it to form a large anal patch, which encloses a slender black sub-marginal line and the last twro spots of the discal series ; from the submedian streak a curved series of triangular blue spots, terminating externally in blackish angular markings, runs across to the cell, with the large patch on which the triangular spots are fused; two series of black spots parallel to the outer margin enclosed in clavate longitudinal pale blue streaks, the outer series submarginal. Body below bluish white. Expanse of wings 65 millim. Lake Mweru. A strikingly distinct new species. 56. EURYTELA DRYOPE. Papilio dryope, Cramer, Pap. Exot. i. pi. Ixxviii. E, F (1779).
