Show 1896.] FROM NYASA-LAND. 837 somewhat worn example of the South-African T. speciosus, to which it approaches much more closely than to any other violet-tipped Teracolus: it is the only known species which can be accurately described as having the apical black border " divided transversely and obliquely by a violet band, very brilliant, rounded externally " : it is moreover, in m y opinion, worthy of consideration that Dr. Boisduval, who (in the Pierince especially) was apt to cut species very fine indeed, regarded the southern insect as typical T. lone, as there can be little doubt that the Doctor had examined the original type. One fact, however, must not be lost sight of:-Mr. Trimen includes T. jalone in the synonymy of his T. lone and says that he does not consider it to be even a marked variety. N o w T. jalone has a conspicuous discocellular spot on the primaries, and its wet-season form bas no more ray on the under surface tbau exists in T. speciosus; only the apical border is conspicuously dusted with white scales, and the violet band is too close to the inner edge of the coloured apical area to be correctly spoken of as an oblique band crossing the border at apex. Air. Trimen gives " White Nile " as the locality of m y type of T. jalone, and that certainly was the locality on the specimen. Should not this have suggested to him the possibility of T. jalone being the dry-season male of T. phleggas, rather than a hardly separable variation of T. Imperator W e certainly have one or two specimens wdiich tend to link T.phlegyas and T. jalone; and the two male examples taken on March 9th represent the spotted and unspotted tyrpes, although neither of them has the pink under surface with transverse ray of the typical dry-season form T. jalone. 95. TERACOLUS HILDEBRANDTI. Callomne hlldebrandtli, Staudinger, Exot. Schmett. p. 44, pl. 23 (1884-88). o*, Mrali, west coast of Lake Nyasa, Sept. 22nd, 1895. A dry-season form of this species, which cannot easily be confounded with any form of T. annce, but must stand between the latter and T. eupompe. The dry-season form differs from the (typical) wet-season form in its superior size, the scarlet instead of orange colouring and greater width of the apical patch on the primaries, the greyer basal area and the pinky yellowish apical area of primaries and groundcolour of secondaries on the under surface ; the black terminations to the nervures are also almost obliterated : it comes nearest to T. annce, var. wallengreni, but the marginal spots are too small, the colouring below too yellow, and the scarlet above too pronounced. 96.
