Show 1897.] BUTTERFLIES COLLECTED IN NATAL. 853 98. TERACOLUS ITHONUS, Butler. Intermediate form (large examples of T. hyperides), Tugela Biver, near Weenen, 2500 feet, 3, 23rd October; Durban, 2 , 7th August, 1896. These examples are labelled as the dry-season form of T. achlne, but T. simplex is the dry phase of typical T. achlne; whereas the dry phase of T. Ithonus is represented by T. Ignlfer (large), T. Ithonus, and T. harmonldes (small); the wet form being represented by T. hero (part), and the intermediate phase by specimens resembling those forwarded in the present collection. T. Ithonus may perhaps prove to be only a race of T. achlne, but it appears to me rather to represent T. antevippe in S. Africa. I do not believe in the presence or absence of a black inner bar to the male apical orange patch being immaterial in the wet phase of a species ; the dry-season forms usually want this black edging. 99. TERACOLUS ACHINE, Cramer. Wet phase, Estcourt, 15th October; Chuga's Hill, near Weenen, 29th October ; Tugela Biver, near Weenen, 6th, 9th, 10th, 12th, 13th, and 16th November. Intermediate phase, o*, 28th October, 3 (In copula, with wet phase), 10th and 14th November, 1896. 100. TERACOLUS ANNAE, Wallgr. Tugela Biver, near Weenen, 2500 feet, 9th, 11th, and 12th November; intermediate phase, 22nd and 30th October, and 12th November, 1896. 101. TERACOLUS MUTANS, Butler. Tugela Biver, near Weenen, 2500 feet, 28th and 30th October, 2nd, 9th, 10th, 11th, 12th, and 15th November, 1896. This is the T. vesta of Trimen and Marshall, but not of Beiche; the latter differs considerably according to the published figures, and is an Abyssinian species. 102. GLUTOPHRISSA CONTRACTA, Butler. 3, Durban, 6th August, 1896. This is labelled as " Pieris saba," but the latter is a very distinct and purely West-African species. 103. BELENOIS THYSA, Hopffer. 3, Durban, 6th August, 1896. 104. BELENOIS MESENTINA, Cramer. Estcourt, 14th and 15th October; Tugela Biver, 22nd, 23rd, 27th, 28th, and 29th October, 6th, 8th, 9th, 10th, and 12th November, 1896. 105. BELENOIS SEVERINA, Cramer.
