Genitalia .—Harjjago roughly oblong with its front extremity 
extended into two strong, long tusks, the upper one being the longest 
and strongest; the cingula is well developed with the hind lower 
extremity projected backwards to a moderate length, the sides 
developing well as they approach the tegumen, which is deeply 
excised in the front, with the falces long and strongly arched and 
having a hook at their extremities; the furca has its arms bent back¬ 
wards, of moderate length and width ; the penis sheath is long and 
straight, the hind half being broad, tapering very rapidly in the 
middle and narrowing to half its width or less, the orifice being tongue¬ 
shaped, with apparently a small opening ; the cheeks of the tegumen 
are clothed with strong hairs, and the extremity of the harpagines 
have also a few scattered hairs which are long and fine.

^. Both wings intensely dark purple blue with very fine dark 
termen. Below both wings pale greyish brown, with the radial 
area whitish; the postmedian stripes very confluent, rather irregular, 
very as to its outer edge in the secondaries, standing out very promi¬ 
nently on the pale ground ; a series of three round almost black sub- 
basal spots, one below vein 8, one in the cell, and one on the 
abdominal margin. 
This is probably the largest of this genus, and its 
strongly-marked underside should enable it to be recog¬ 
nised at once. On the West Coast it is common in many 
places, but I have been unable to trace it into Central, 
South or Eastern Africa.
