In T. leo the saffron-yellow of the primaries extends only from the inner margin upwards to the first median branch, whereas in T. halimede it spreads to above the third branch ; all the black markings are smaller and much more prominent in T. leo, but the female has a blackish bar across the cell of primaries, limiting the grey basal area ; this sex also has the apex of primaries and the whole ground-colour of secondaries of a sandy-buff hue, the latter wings having a conspicuous white spot at the end of the cell and an unevenly arched series of brown spots across the disc ; some females have no saffron-yellow on the upper surface. The female of T. miles proves to be a black-and-white form, not unlike the white female of T. pseudacaste, but with less black above, the veins at apex of primaries below not blackened, and the secondaries buff instead of white; there is, however, a red-tipped female which, I think, belongs to the same species and which has the apex of primaries and ground-colour of the secondaries below sulphur-yellow. The female of T. citreus from Kilima-njaro is, on the upper-side, very like that sex of T. topha, but the black markings are reduced and more sharply defined ; below it more nearly resembles T. xanthevarne 2 > the secondaries white with pale yellowish-brown markings and olive and black mottling as in T. eucharis $, but with a conspicuous brown-edged white discocellular spot. The synonymy of T. incretus will, as I suspected, stand as follows:- TERACOLUS INCRETUS. 2 . Teracolus incretus, Butler, Ent. Mouth. Mag. xviii. p. 146 (1881). o* . Callosune vulnerata, Staudinger, Exot. Schmett. pi. 23. fig. 21 (1884). Both sexes of this, the largest species of the T. evarne group, were obtained both by Bishop Hannington and Mr. Jackson ; so that there is now no doubt of the correctness of my expressed opinion that C. vulnerata would prove to be the male of m y species ; the fio-ure by Staudinger is poor, the colouring of the secondaries being exaggerated and the black bordering of the primaries incorrectly drawn, still it is as good as the majority of the illustrations in this book, which (whatever its faults may be) has the merit of being cheap. As with other species of the T. evarne group, a white form of the female is by no means uncommon ; it is a little smaller than the yellow female and, excepting in its superior size and in the details of marking on the under surface, greatly resembles that sex of T. topha. The male, on the under surface, is extremely variable ; indeed no two specimens are alike ; the following may be noted:- a. Secondaries below whitish sulphur, excepting at the borders, which are pure sulphur-yellow ; a minute dusky costal spot, dark |
