Lycaenesthes otacilia, Trimen. (Plates II, fig. 1; 
VI, fig. 14.) 
L. otacilia, Trimen, Trans. Eut. Soc. Lend., 1868, p. 90; 
id. S. Afr. Butt., p. 102, PL 7, f. 8 (1887); id. Aiiriv.,

Nassau, Iv, p. 156 (1902). 
d. With the blue of a dullish, sub-lustrous violaceous shade, 
confined in the primaries to the cell, the fold, and below vein 3 in 
the radial area ; in the secondaries the blue is evenly di.stributed 
with a broad brown termen. The undersurface is warm greyish 
brown with the spots closing the cells in both wings, and the post¬ 
median fasciae broadish and prominent; the secondaries have a 
prominent small dark round sub-basal spot below vein 8, another 
paler one in the cell, and a third just below the cell. 
I have a female which is entirely brown, without any 
blue colour at all. It is a small, well-marked species, 
widely distributed. Dr. Pagenstecher’s L. dulcis, the type 
of which is before me, is only a small specimen of it.

Genitalia. —The harp)ago is somewhat lozenge-shaped, with the 
front termination divided into three deeply excised points or fingers. 
The cingula is strongly developed, with the lower basal hind 
extremity well produced backwards and strong, the sides approach¬ 
ing the tegumen broad ; the tegumen is well developed, very 
deeply excised at the front apex, with the hind apex practically 
level with the cingula ; the falces are long and broadish, very broad 
for the size of the insect, well curved and tapering gradiially to the 
extremity ; the furca is rather long with arms of moderate width. 
The penis sheath is almost boat-shaped for nearly half its length ; 
a short depression occurs after this point, but it rises again, and 
then tapers to the front tip rapidly, the upper portion being more 
or less open—it is unusually stout. 
Lycaenesthes otacilia kikuyu, var. nov. 
(Plate II, fig. 2.) 
(J. Differs from otacilia. Trimen, in that all the wing is blue, 
leaving only the apex of the primaries broadly brown tapering 
rapidly along the termen to the torniis, whilst the secondaries have 
also a larger blue area practically up to the termen, except just at
