1910.] FROM TROPICAL WEST AFRICA. 357 



Hah. Bitje, Ja river, Oameroons, 2000 ft,, wet season 

 (6r. L. Bates). 



Type, Mus. Druce. 



The markings on the under side' of the hind wing give this 

 insect a very different appearance from any other described in the 

 genus. 



Pentila pardalena, sp. n. (Plate XXXIII. fig. 1, d •) 



Male. Upper side : both wings pale yellow, darker towards the 

 base, heavily spotted with black over the cellular and discal areas ; 

 apex and outer margins broadly black, containing rows of pale 

 yellow spots. Under side clear pale yellow, darker on the hind 

 wing and towards base of fore wing. Discal and cellular black 

 spots as above, except on the hind wing where there are several 

 additional black basal spots. The apex and outer margin have a 

 marginal and a submarginal row of large elongated black spots 

 running alternately. 



Expanse 1 T 7 ^ inch. 



Hob. Bitje, Ja river, Cameroons, 2000 ft., dry season (G. L. 

 Bates). 



Type, Mus. Druce. 



This is a more heavily spotted form than Pentila christina 

 Suffert* (a photograph of the type of which I have before me) and 

 the ground-colour below is clear, not speckled as in that insect. 



Pentila inconspicua, sp. n. (Plate XXXIII. fig. 3, § .) 



Female. Upper side : allied to Pentila petrea Hew., paler and 

 without the reddish tinge. In the fore wing the dark apical 

 border is much broader, and there is an additional black spot 

 on the disc situated near the base of cell 2. On the hind wing 

 there is trace of a submarginal row of small black spots situated 

 between the veins, which in some specimens is clearly indicated. 

 Under side : differs from that of P. petrea by the addition of the 

 black spot in cell 2, by the absence of the two black spots at the 

 angle in the fore wing, and by the submarginal row of spots 

 on the hind wing being placed further in from the margin. 



Expanse 1 ^ inch. 



Hah. Upper Kasai district, Congo Free State, Uganda. 



Type, Mus. Druce. 



This insect is even paler than P. preicssi Staud., a large series 

 of which we have received from the same locality. 



The British Museum collection contains six specimens from 

 Entebbe, Uganda. 



Pentila paradoxa, sp. n. (Plate XXXIII. fig. 4, ^ .) 



Male. Upper and under sides : both wings semitransparent, 

 creamy white, without markings. Basal third of costal margin of 

 fore wing on both surfaces grey. "When held at an angle the 

 whole of the upper and under surfaces is suffused with a greenish
