gradate cross-veins just behind the nexus. There are also slight touches of brown along 
the basal portion of the cubital vein where joined by cross-veins in the fore wing, and 
there are two conspicuous oblique brown streaks ; one covering the cubital are and being 
half a dozen or more cells long, and the other traversing the base of the terminal forks of 
the radial sector, and being parallel to the hind margin. In the hind wing there is but 
one streak, corresponding in position to the one last mentioned, but being a little larger, 
filling the space between the marginal forks and the last gradate series of cross-veins and 
extending to the apex of the wing. 
Legs slender, yellow, sprinkled with fuscous dots that are more or less confluent 
about the apices of femora and tibiz. The colour is paler on each succeeding pair, the 
hind femora being wholly yellow, except a spot at the tip. The spines that thinly clothe 
all the legs are blackish, and the spurs and claws are brown. The spurs are gently 
curved, but the claws are straight to very near their tips. The terminal tarsal seement 
is clothed beneath with a thick brush of deep black clavate hairs. Abdomen wholly

obscure pale brownish, with a suggestion of two dark brownish areas toward the ends of 
each segment dorsally. The first tarsal segment is slightly shorter than the fifth, which 
nearly equals the second, third and fourth taken together. 
This species lacks the prothoracic stripes of Ff’. bistrigatus and also the brown dashes 
along the cubital vein, and it has, along with lesser markings, the distinct conspicuous 
brown streak along the cubital are in the fore wing, which that species lacks. It falls in 
the subgenus Distoleon Banks.

I refer two specimens from Aldabra with considerable hesitancy to Walker's species, 
the type of which I have not seen. They agree fairly well in colour and markings but are 
smaller in size than the measurements given by Walker.
