African sjiccies of the Lycaenesthes group of Lycacnidae. 9 
Cupidesthes arcscopa, sp, nov. (Plates I, fig. 2 ; IV, fig. 2.) 
g. Both wings blackish brown. Primaries with a restricted area 
of very pale silvery greenish blue, restricted to below the cell. 
Secondaries with the pale bluish area below vein 6, extending well 
beyond the cell and up to the abdominal margin and the tornus, 
these latter areas becoming whitish. Underside : both wings pale 
brownish almost entirely covered with white scales, so as to look 
w'hitish, the spots being only marked out by their brown margins, 
but being filled in with white. Primaries with a spot closing the cell; 
postmedian stripe very broad, the third and fourth spots confluent 
shifted outwards, fifth and sixth each slightly inwards ; to this point 
the spots form one continuous band, but the first spot on the costa 
is absent, the seventh spot is isolated and shifted right inwards 
so as to be below the spot closing the cell. Secondaries with a 
sub-basal subcostal pale brown spot, an oblique spot closing the 
cell; postmedian stripe with the third spot shifted out on to the 
outer edge of the second, fourth and fifth confluent shifted slightly 
out, sixth oblique shifted slightly in, seventh and eighth angled 
spot shifted far in below and almost to touch the spot closing the 
cell, an indefinite subterminal brown line interrupted at the veins, 
a trace of a preterminal interrupted line, a small black terminal 
spot between veins 2 and 3 and a larger one at the angle, with a 
trace of a few metallic scales and slight yellow internal edges. 
5. Both wings darkish brown. Primaries with a white central 
roundish patch. Secondaries with a larger patch below vein 6 to 
the inner margin, and occupying about half the radial area. Under¬ 
side as in the male.

Type in the National Collection. 
Mr. H. H. Druce has a series of this species from the 
same locality with females, and my description of this sex 
is from one of his specimens. I have no doubt in my 
own mind as to the determination of the sexes. 
Genitalia .—Harpago somewhat roughly and narrowly reniform at 
the extreme base, suddenly reduced to an exceedingly fine, narrow, 
long point, with long, strong bristles most of its length. Cingula 
rather narrow, tapering wider towards the tegumen, which is well 
excised in the front of the dorsum (or dorsal apex). Falces very long 
and narrow, well curved at a quarter from their sockets. Furca 
with short, narrow arms rising directly from the harpagines, and
