Genus STIBOLEPIS, Butler. 

 STIBOLEPIS ATOMARIA, new species. 



Male. — Front reddish. Collar, pata<ii;i'. and ujjper side of tnorax 

 gray. Legs and mider side of thorax and upper and under side of 

 abdomen ocherous. The wings are uniformly light gray upon the 

 upper side, and thickly sown with dark scales, producing a " salt and 

 pepper" effect. Upon the costa of the primaries tliere is a faint tend- 

 ency of these black atoms to arrange themselves in bands, especially 

 near the base of the wings. The margin is very narrowly dark gray 

 and the broad fringes are pale ashen. The under side of the wings is 

 uniforml}- pale gray, shading into ocherous at the base. The wings 

 are thickly dusted over with dark scales upon the outer half and on 

 the costa. These scales are so arranged, just beyond the cell, as to 

 present the appearance of four or five faint and narrow bands. The 

 anterior wings, near the base and beloM^the cell, have few markings. 



Expanse of wings, 55 mm. 



The type is unicpie in the collection, and is labeled '• Zanzibar'* by 

 the authorities of the Museum. But I have a specimen in my own col- 

 lection which came from near Taveta, and was collected by a French 

 naturalist, so that the type was probably from the interior. 



Family LIMACODID.E, Boisduval. 



Genus COSUMA, Walker. 



COSUMA MARGINATA, new species. 



(Plate YII, fig. 11.) 



Male. — Antenuie, head, and body dark olivaceous. Upper side: An- 

 terior wings pale olivaceous and the posterior wings still i>aler. Both 

 wings have a silky luster. There is a well-defined round, cream-col- 

 ored mark at the end of the cell of the primaries. The margins have a 

 very narrow stramineous border interrupted by the darker nervules. 

 The fringes are of the same color as the body of the wings. Under 

 side: Both wings are marked as upon the upper surface, but are paler, 

 and the marginal maculations are larger and more distinct. 



Expanse of wings, 28 mm. 



The type, in the Kational Museum collection, is unique.
