106. MACROGLOSSA TROCHILUS, var. TROCHILOIDES. 



Macroglossa trochiloides, Butler, P. Z. S. 1875, p. 5. 



Nyankowa Mt., Nyika, 6500 feet alt., April 9th, 1895. 



" Green and orange Humming-bird Hawk " (R. (7.). 



This form of M. trochilus appears to cross the African con- 

 tinent 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 in 

 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 ^NESCENS, 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 ; antennae 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 inter- 

 nally. Expanse of wings 37 millim.

" Black-plumed Humming-bird. Taken in tent fluttering round 

 candle-lantern by night" (R. G.}. 



When in fresh condition this must be an exceedingly beautiful 

 insect.
