BUTLER ON BUTTERFLIES [Jan. 14, first and second median branches terminating in black spots and the spots on the disc much larger; the secondaries show a broad bright saffron-yellow costal streak and a paler longitudinal sub-median streak, and the nervures are tipped with black. 3 , Foot of Jakwa Mt., 3210 feet, Henga-Nkamanga, Jan. 29th; o* 2 , Henga, Jan. 30th and 31st, 1895. 3, " Black and gold-tipped White "; 2 , " Black-tipped mother-of- pearl underwing White" (R. ft). The female now received is smaller than the type from Delagoa Bay, and has a broader black internal border to the primaries (in which respect it more nearly corresponds with the male); but of a pair received from the Victoria Nyanza, this border in the female corresponds with that of the type. As more examples of these representatives of T. eris come to hand, the fact that they are true to locality seems to be gradually established on a firmer basis. 76. TERACOLUS MUTANS. 2 . Teracolus mutans, Butler, Ann. & Mag. Nat. Hist. ser. 4, vol. xix. p. 459 (1877). 3 . Nearly resembles T. vesta on the upper surface, but the base of the wings is dusted with bluish grey instead of black, the outer area creamy ochreous (less salmon-tinted than in T. vesta), pattern exactly as in the female, therefore much more yellow throughout than in T. vesta. 3, Henga, west of Lake Nyasa, Feb. 1st, 1895. "White-centred, yellow and black-mottled White. Difficult to take and not common" (R. ft). The arrival of this male is especially interesting to me, as Prof. Aurivillius was inclined to believe m y T. rhodesina to be the male of T. mutans, considering that the differences of pattern might be sexual: it is now satisfactorily proved that there is no difference of pattern between the sexes, but only in the colouring of the outer half of the upper surface1; precisely what might have been expected, from what we know of the sexes of T. hanningtonii and T. amelia. 77.

A n especially well-marked specimen, with bold black spots on the under surface. It has recently been suggested that this may be a seasonal form of T. regina, of which Mr. Trimen formerly regarded it as a variety; the only odd thing is that typical 1 This buff colouring is limited by the black band as in T. vesta. |
