This is supposed to be an extreme wet-season form of T. evenlm: Mr. Trimen's note in his ' South African Butterflies,' vol. iii. p. 128, seems somewhat contradictory. Of T. slpglus he says :- " The male is inseparable from the larger darker specimens of male evenlna . . . ., though it is somewhat more heavily marked." I consider T. sipylus to be a distinct representative form. 98. TERACOLUS PROCNE. Anthopsyche procne, Wallengren, Kongl. Svensk. Vetensk.-Akad. Handl. 1857, Lep. Shop. Caffr. p. 12. Mpata, west of Lake Nyasa, August 2nd, 1895. Probably only a varietal form of T. theogene; but both are dry-season forms, of which it is extremely likely that TT. ocale, microcode, angolensis, and arethusa are more or less localized wet-season forms. 99. TERACOLUS CINCTUS. Teracolus cinctus, Butler, Ann. & Mag. Nat. Hist. ser. 5, vol. xii. p. 105 (1883). Dry-season form o* 2 J Loangwa Biver, Senga, Sept. 5th and 13th,' 1895. Differs from the typical wet-season form in the reduction of the internal black streak on tbe primaries, which is represented by a greyish smear ending in a darker spot, and in the rosy colouring of tbe secondaries on the under surface. 100. TERACOLUS SUBFUMOSUS. Teracolus subfumosus, Butler, P. Z. S. 1876, p. 139, pl. vi. fig. 3. 6", Loangwa Biver, Senga, Sept. 12th, 1895. This is doubtless a wet-season form of some other named Teracolus and allied to T. elone: it is not at all likely to be a form of the West-African T. antlgone, unless the latter can be linked by a perfect series of intergrades to T. elone, which at present I am not prepared to admit to be a fact. If T. antlgone and T. clone are distinct species (as claimed in the ' South African Butterflies '), the forms from Western Africa must be kept separate from those of the South. T. phlegetonla is allied to T. eione, but does not closely agree with it in pattern, though both represent the extreme wet-season types of the country which they inhabit. In like manner, T. xanthus will probably prove to be a wet-season form of T. odysseus, inasmuch as both forms inhabit the White Nile, and are so much alike that their proper females were originally transposed ; the differences between them are similar to those which exist between T. eione and T. subfumosus, or between T. phlegetonla and T. antlgone.
