This form of MV. 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: IW. trochiloides therefore will probably 
prove to be a dimorphic form of M. trochilus which becomes 
permanent on the N.W. coast.

When in fresh condition this must be an exceedingly beautiful 
insect.
