African species of the Lycaencsihes group of Lycaenidae. 49 
which is deeply excavated at front apex and less so at the back, the 
narrow neck being slightly raised ; the cheeks are evenly rounded 
off to their lower angle ; the falces being very long and strong, curved 
sharply well above their sockets, and with the tip developed into a 
sharp, strong hook ; the furca is very long, curved well back, with 
arms long and narrow. Penis sheath very wide for its hinder half, 
gradually tapering narrowly to the tip, whose orifice is excavated into 
a hollow point. The cheeks of the teguinen are furnished with fine 
hairs, and the upper apex has also a few shorter ones sparingly placed 
down the front edge. 
Lycaencsthes versatilis, sp. nov. (Plate II, fig. 10.) 
^. Both wings blackish bi’own. Primaries with the area below 
the cell and between veins 1 and 2 dull lustrous purplish blue to a 
quarter from the termen ; below vein 2 there is a trace of a yellow 
dash showing through the blue. Secondaries with a short, dull, 
lustrous blue stripe across the wing in the postmedian area from 
vein 2 to 5. Underside white with greyish-brown markings. 
Primaries with a basal subcostal dash, below which is a broad dark 
mark along the inner edge, angled suddenly upwards at vein 2 ; cell 
closed by a large spot, with another below it below vein 2 ; post¬ 
median stripe further out than usual, slightly curved, shifted out at 
vein 6; subterminal line broad, touching the postmedian stripe at 
vein 2. Secondaries with a broadish basal dash, having a dot below it 
on the inner margin ; cell closed by a largish spot; postmedian stripe 
so broken up as not to appear in sequence at all, viz. costal spot 
very dark, with an indefinite mark below’ it; a dark, confluent spot 
between veins 4 and 6, shifted well out, follow’ed by a less dark spot 
between veins 2 and 4 shifted iirwards ; angled spot below this very 
dark ; subterminal line broadish ; a black terminal spot between 
veins 2 and 3, and another at the angle, both with metallic scales 
and margined with reddish. 
Expanse 27 mm.

Type in the National Collection. 
I have described this underside as white ; it is no doubt 
brown, almost entirely covered with white superimposed 
scales, and there are therefore, strictly speaking, no white 
lines around the spots. The species is in markings nearest 
to Neurypexina lamproclcs, Hew., but the neuration is 
different, and it will therefore, with L. huchholzi, Karsch, 
hold a somewhat isolated position in this genus.
