allied to the insects belonging to that section of the genus Rhopalo- 
campta which contains R. unicolor, Mab., and R. libeon, Druce, but 
thoroughly separate from them by reason of the different structure 
of the palpi and the antenne. 
319. A. DImmpIA4, sp. nov. (Plate V. fig. 7.) 
¢. Antenne, body, and wings both above and below uniformly 
dark brown, with a slight greenish sheen on the disc of the primaries 
when viewed in strong sunlight. The palpi on the lower side are 
orange-coloured. Expanse 40 mm. 
Hab. Gaboon (Mocquerys). 
The type of this insect is contained in the collection of 
Dr. Staudinger and is unique. On comparison with A. holocausia, 
Mabille, the chief points of difference are the smaller size and the 
more obscure colouring, for A. holocuusta has the primaries and 
secondaries somewhat plentifully sprinkled with golden-orange 
scales near the base, and the general coloration is brighter. There 
is no doubt in my mind as to the specific distinctness of this form 
upon comparison. The facies is quite distinct, though the species 
are very closely related.

Very common on the Ogové River.

Rhopalocampta libeon, Watson, P. Z.S. 1893, p. 129. 
Hab. Angola (Druce). 
Closely allied to R. unicolor, Mab. 
323. R. Brussavxi, Mab. 
Ismene brussauai, Mab. Bull. Soc. Ent. France, 1890, p. ccxxi. 
Hab. French Congo (Mabille). 
This species was described by Mons. Mabille from a defective 
example. It is evidently very near R. libeon and R. unicolor.
