AURIVILLTUS, AFRICAN LASIOCAMPIDAE. 9 



Striphnopterygridse. 



Drepanojana apicalis n. sp. — ^. Upper side: both wings 

 uniformly dark umbra-brown ; före wings at the costa near 

 apex in the areas 7 and 8 with a creamy spöt and with a 

 similar small submarginal dot in 6; ciliae yellowish speckled 

 with brown. Under side: as above but the ground colour 

 more reddish brown. Body above dark reddish brown, below 

 yellowish; antennae dark grey, bipectinate. Expanse 40 mm. 



Gold Coast: Bibianaha, 70 miles N. W. of Dimkwa; 

 700 ft; Nov. 27. 1910. — H. G. F. Spurrell. — British 

 Museum. 



Agrees in venation and other structural characters com- 

 pletely with Drepanojana fasciata and belongs undoubtedly 

 to that genus. The outer margin is, however, completely 

 straight and not falcate as in the female of fasciata. The 

 form of the före wing may be different according to the sex. 



Phiala incurva n. sp. — J". Wings above white; fore- 

 wing dusted with a few black scales in the cell, a little 

 behind the middle with a continuous rather thick black 

 fascia, which is slightly but distinctly convex basad; the 

 fascia begins at inner margin about 8 mm. from the base 

 and ends quite near costa a little before the apex; hind wing 

 with a straight, postmedian fascia of black scales, more de- 

 veloped at the veins, from inner margin to costa about 

 5 mm. from the apex. Wings below påle yellow without 

 markings. Antennae, forehead, breast, legs and abdomen 

 brownish yellow; tarsi speckled with black. The female 

 only differs by both wings, but espeoially the före wing, being 

 above densely speckled with black scales and the ground 

 colour being more greyish. Expanse 38 — 40 mm. 



German East Africa: Usanga District, 3,500—4,500 ft; 

 November and December 1910. — S. A. Neave. 



Easily distinguished from allied forms by the incurved 

 fascia of the före wing and the straight fascia of the hind 

 wing.
