410 MR. H. H. DRUCE ON BUTTERFLIES [Apr. 6, 
ACLEROS SPARSUM, sp.n. (Plate LX VII. fig. 4.) 
Male. Upper side: both wings uniform blackish brown, fore 
wing without markings, hind wing with the anal angle and 
outer margins almost to the apex irregularly pure white. 
Under side: fore wing blackish brown, with the apex and outer 
margin laved with white and grey, darkest along the costa. 
Hind wing laved with grey and white, whitest towards the base 
of the costa and at the anal angle. Thorax black above, white 
below. Abdomen black above, white towards anus and white 
below. Palpi: first jomt white, second joint white at the base 
then buff interspersed with black, terminal joint black. Legs 
black and white, spurs white. The antenne are black, with the 
usual pure white spot just before the apex. 
Expanse 1? inch. 
Hab. Bitje, Ja River, Cameroons, 2000 feet (G@. LZ. Bates). 
Dry season. 
Described from two specimens, 
This is a large species, and is perhaps nearest to A. lewcopyga 
Mabille*, originally described from Madagascar, but found to also 
inhabit W. Africa, but has less white on the hind wing above 
and is differently marked below. 
ACLEROS KASAI, sp.n. (Plate LX VII. fig. 5.) 
Female. Upper side light brown with whitish hyaline spots. 
Fore wing: three minute spots placed in a line from the costa, the 
lower one being the largest, about halfway between the end of 
the cell and the apex. Two spots in the cell at the end placed 
one above the other; a spot between the two lower median 
nervules and a smaller spot above and resting on the submedian 
nervure about its middle. Cilia brown. Hind wing with a 
distinct double spot forming a triangle towards the end of 
the cell. Anal angle, outer margin, and cilia pure white. 
Under side—Fore wing: costa rusty brown, discal area brown, 
spots as on upper side, outer margin with a pale pinkish-brown 
patch below the apex. Central inner marginal area broadly 
whitish. Cilia pale brown. Hind wing laved with pinkish 
brown, with darker shadings at the apex and along the inner 
margin. An outer marginal row of darker brown shades.  Cell- 
spot as above, brown-edged. Anal angle white. Cilia white. 
Abdomen brown above, with the ventral half pure white; white 
below. Antenne brown, with the usual white spot on the club 
just before the tip. 
Expanse 12 inch. 
Hab. Upper Kasai District, Congo Free State (P. Landbeck). 
This is a large species, not very closely allied to any which I 
can find described. The clear spots on the fore wing and the 
distinct central spot on the hind wing at once distinguish it.
