one at the upper and the other at the lower outer angle. In one or two specimens 

 these spots are quite indistinct, and in others they are quite conspicuous. In one or 

 two specimens the costa of the fore wing at the base has a few dark scales. 



9 . Like the male, but with greater expanse of wing, and with heavier bodj- and 

 reduced antennae. Expanse, cf, 38-42 mm.; 9 , 50-54 mm. 



Tliis insect runs to Sopelia, according to the table given by Aurivilliiis 

 (1904, Arkiv Zool., II, part 4, p. 62), and I have no hesitation in locating 

 it here, but I have not been able to find a description or figure in that or 

 any allied genus which fits the species and therefore describe it as new. 

 There are seven males and four females in the collection. They were all 

 taken at Medje in June and July, except one male caught at Gamangui 

 on February 17 and a female captured at Medje on April 6, 1910. The 

 types are in The American Museum of Natiual History; paratypes have 

 been reserved for the Holland Collection in the Carnegie Museum.

There is a single male specimen of this interesting insect which 

 agrees absolutely with the description of the genus and species given by 

 its author. His description is fovmded upon a single male contained in 

 the Museum at Brussels. There are two females in our collections, one 

 in the Holland Collection from the valley of the Ogove, the other in the 

 general collection from Cameroon, as well as a male in the Holland Col- 

 lection. The female is much larger than the male, but in neuration and 

 markings the two sexes agree exactly. The antennae also, as might be 

 predicated without any information, are less plumose and shorter in 

 the female. Elxpanse, 9 , 47-52 mm. 



'I cannot resist the opportunity to describe another species of this rare genus of insects to the 

 existence of which my attention has been called by my assistant, Mr. Hugo Kahl. 

 Leucoperina kahli, new species 



d". -Agreeing structurally in every particular with L. atroguttata .Aurivillius, but differing in having 

 the pnnianes pale uniformly semi-translucent fawn-colored, and the secondaries, which are white, 

 clouded at the inner angle with pale brown. The wings are less diaphanous than is the case in atro- 

 guttata; the black mark on the fore wings at the origin of vein 2 is the same. Expanse, 38 mm. 

 Cameroon. Type in Carnegie Museum.
