1896.] BUTTERFLIES OF THE FAMILY HESPERIID ®. 43 
bright rufous, with the costal margin broadly black, the inner 
margin somewhat broadly margined with black, the outer margin 
detined with a moderately broad black marginal line. The cilia are 
rufous. On the cell is a broad oval patch of raised scales, dark 
brown in colour. On the underside the wings are more obscurely 
marked, the spots of the,upperside reappearing upon the primaries, 
but much less sharply defined. The secondaries lack the black 
costal border and are marked on the disc by a number of minute 
silvery spots, surrounded by fuscous shadings. Of the spots, the 
one at the end of the cell is the most conspicuous. 
@. The female presents the usual broad divergence from the 
male which is characteristic of the genus, and superficially does not 
apparently differ very widely on the upperside from the female of 
O. adosus, Mab., an allied species. On the underside, however, it 
agrees almost absolutely with the male in the style of marking.

Hab, French Congo (MMocquerys). 
This is one of the most distinctly marked species in the genus.

3. Very closely allied to 0. chrysauge, Mab., of which it may 
be a small variety. It differs from the type of O. chrysauge in 
having the apex more broadly black, the subapical yellow spots not 
being confluent with the broad orange-yellow discal tract as in 
chrysauge. The outer marginal black border is also relatively 
wider than in chrysauge, and the raised patch of scales on the cell 
of the secondaries is bright fulvous, not dark brown as in chrysauge, 
elongated, and not broadly oval as in the latter species. On the 
underside of the secondaries the outer margin is not so broadly 
marked with fulvous as in chrysauge. 
Expanse 22 mm. 
Hab. Gaboon (Mocquerys). 
141. O. rHops, sp. nov. (Plate IV. figs. 43, 69.) 
3. Closely allied to O. thora, Ploetz, from which it is to be dis- 
tinguished by the fact that the black margin of the primaries is 
narrower than in thora and not irregular inwardly as in thora, 
but uniform, and by the fact that the underside of the secondaries 
is dark brown over the greater portion of the area, whereas in 
thora it is light, the outer margin being pale yellow in thora, and 
the basal half pale glaucous clouded here and there with darker 
brown. 
¢. In the female the spots upon the primaries are broader than 
in the female of thora, while on the secondaries the fulvous spot 
in thops is smaller than the corresponding spot in thora. 
I have a long series of both males and females, some of the 
examples taken in coitu, and it is perfectly plain that the two 
species are distinct, though superficially thops and thora show 
considerable likeness to each other.
