Nyankowa Mt., Nyika, 6500 feet alt,, April 9th, 1895. " Green and orange Humming-bird H a w k " (R. ft). _ This form of M. trochilus appears to cross the African continent from west to east; it differs from the southern type principally in the blacker and therefore better-defined outer border to its secondaries. There can, however, be no doubt, from the fact that an example of the southern type was obtained by Mr. Scott Elliot, that the ranges of the two forms overlap m South-eastern Africa: M. trochiloides therefore will probably prove to be a dimorphic form of M. trochilus which becomes permanent on the N . W . coast. 107. MELITTIA JENESCENS, sp. n. (Plate VI. fig. 10.) Allied to M. natalensis; primaries slightly narrower, purplish indigo, with the same transparent spot between the second and third median branches; secondaries hyaline with black veins, narrow black margins, and dust-grey fringe paler at the edge; head olive-brown ; antenna? purplish black above, shining straw-yellow below, and deep ferruginous in front; collar and thorax golden brassy, with green reflections; abdomen purplish indigo, with dorsal golden brassy transverse bands on the front of each segment: primaries below becoming brownish grey from beyond the cell; otherwise the wings are as above: palpi and face white stained with yellow; pectus slaty black, the sides in front and the front legs golden brassy, tibial and tarsal joints reddish; middle legs golden to the end of the tibia, tarsus purplish black ; posterior legs blackish brown, the tibial joints densely clothed with long black, red, and white hairs ; tarsi black externally, white internally.
