being morphologically identical with 7. pulchripes and 
T. jeanneli, has light blue wings, as in the latter species, 
and violet tibiae—of a shade intermediate between the 
two. Two specimens (g and 9) of 7’. guineensis from Sierra 
Leone are quite indistinguishable from Uganda specimens, 
except that their wings are light orange at their base and 
strongly infumated towards the apex; they are very close 
to the true ZT. pulchripes. I believe that the whole of 
Tropical and South Africa is inhabited by the one species— 
very variable in the coloration of the wings and hind 
legs, as well as the head (but not in morphological 
characters)—T’. pulchripes, which may be divided into many 
geographical races, connected by transitional forms. These 
races have been described by different writers as distinct 
species, and I believe that the following should be included 
in pulchripes, as subspecies of it only :— 
coerulipes Sjéstedt, 1913. 
guineensis Krauss, 1891. 
ie var. maculosa Krauss, 1891. 
nigrovittatus I. Bolivar, 1914. 
jeanneli I. Bolivar, 1914. 
Some of these, after careful investigation and examina- 
tion of large series of specimens from different localities, 
may even prove to be mere individual aberrations of the 
same subspecies. More material is certainly wanted to 
confirm this opinion, but I think it more useful to raise 
the question im this form than to describe every colour 
variety as a distinct species.

The only differences of this form from the typical one 
consist in the coloration of the wings, which are light blue 
at the disk and slightly infumated towards their apex, 
and in the coloration of the hind tibiae, which are not 
sanguineous in the distal part, as in the typical form, 
but more violaceous. I believe this form to be a kind of 
link between the subspecies pulchripes and jeannelv.
