On a small Collection of Butterflies from the Nandi District, Uganda Protectorate, Eastern side of Lake Victoria; made by Captain Hobart, of the Grenadier Guards. By A R T H U R G. BUTLER, Ph.D., F.L.S., F.Z.S., &c. [Received November 1, 1899.] The collection of which this is an account is small but interesting, the whole of the specimens having been captured by Capt. Hobart on the march. Among them is a Gymoihoe which appears to be quite new, and of considerable interest from its affinity to Western forms; also Planema poggei 6, and Acrcea leucographa, an extremely beautiful variation of the Western Acrcea admatha. NYMPHALIDcE. 1. AMAURIS ALBIMACULATA Butl. The white spots on the primaries are reduced in size in all the specimens, but we have similar examples in the Museum collection. 2. CHARAXES CANDIOPE Godt. One male example. 3. CYMOTHOE HOBARTI, sp. n. The male above vermilion suffused with carmine, the costal and outer margins narrowly black ; primaries with a small apical patch and one subapical spot, sometimes continued indistinctly as a submarginal series ; secondaries with well-defined submarginal black spots commencing with a sagittate spot at apex and terminating in an obtusely biangulated linear marking above anal angle; abdominal border pale brown; body bronzy brown, the palpi and under surface of antennal club tawny. The under surface is of a sandy-brownish hue, with fleshy and weak olivaceous changeable tints ; the general pattern is that of C. uselda, the markings on the basal half being sharply outlined in black; the nearly straight dividing line beyond the middle is dark rich brown in the type, but weakly defined in a second smaller male ; the series of A-shaped markings beyond the dividing stripe are alternately pale pearly pink and olivaceous greyish, the outer series of the latter tint uniting into a continuous wavy submarginal line dotted with blackish between the nervures ; the femora are whitish. Expanse of wings 42 to 58 millim. The female nearly resembles that sex of G. aclela, excepting that the basal area is internally suffused with olivaceous greyish and externally with pale sandy yellowish, the discal series of sagittate markings is weaker in the primaries and very much more so in the secondaries; on the under surface the general appearance is |
