allied to the insects beloDging to that section of the genus lUiopalo- 

 campta which contains R. unicolor, Mab., and R. Z«6eo»t, Di'uce, but 

 thoroughly separate from them by reason of the diflfereut structure 

 of the palpi and the antennae. 



319. A. DiMiDiA, sp. nov. (Plate V. fig. 7.) 



S . Antennae, 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. 



Hah. Gaboon (Mocquerys). 



The type of this insect is contained in the collection of 

 Dr. Staudinger and is unique. On comparison with A. holocausta, 

 Mabille, the chief points of difference are the smaller size and the 

 more obscure colouring, for A. holocausta 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 Cacies is quite distinct, though the species 

 are very closely related.

 This species was described by Mons. Mabille from a defective 

 example. It is evidently very near R. libeon and R. unicolor.
