Hab. Kikuyu, Sept. 1889. 



9. AcR.EA MELANOXANTHA, sp. n. (Plate XVII. fig. 4.) 

 Black and yellow as in A. circeis, wliicli it somewhat resembles, 



especially on the underside ; it is, however, much smaller, and has 

 fewer transparencies on the fore wing. 



Fo7-e wing black, with a double row of spots ; two are twin- 

 spots, one being at the posterior end of the cell, and the other 

 adjoining it at the base of the disk, between the first and second 

 median nervules. These two spots are irregularly oblong in shape 

 and of a yellow colour. A second row of siibapical spots consists of 

 three, also irregularly oblong in shape, but transparent white ; these 

 are situated in juxtaposition, below the fifth subcostal and second 

 radial nervules. 



Hind wing blackish, with a patch of yellow, irregular in shape, 

 occupying the middle of the wing. The basal area of the wing is 

 black, extending in a black band along the costal margin, which 

 joins the broad black border of the hind margin. The yellow colour 

 of the hind wing reaches to the inner margin about its centre ; the 

 black nervules are indicated plainly as they cross the yellow area, 

 and two black spots are also visible on the yellow of the upper 

 margin of the discoidal cell. 



Underside. Fore wing ashy brown for the basal two thirds, 

 the white spot of the upperside indicated below, with a dusky spot 

 at the base of the fifth subcostal nervule ; apical area and hind 

 margin of the wing coppery bronze, each interspace with a black 

 mesial line, the nervules also marked out in black ; the hind margin 

 fringed with black. 



Hind wing. Basal area ochreous yellow, deeper near the base, all 

 this pale area numerously dotted with black sjiots, clustering nearer 

 to the base and on the inner margin ; hind margin with a broad band 

 of coppery bronze, with the same mesial line of black and the black 

 lines of the nervules also strongly indicated ; the hinder margin 

 fringed with black. 



Exp. 2 inches. 



Hab. Mount Elgon, Feb. 1890. 



10. AcR^A OREAs, sp. H. (Plate XVII. fig. 5.) 



Resembling A. melanoxantha on the upper surface, with two rows 

 of triple white spots, the subapical ones, however, not being trans- 

 parent. The hind wing is further different in the yellow central 

 patch being entirely shut in by black. The under surface, however, 

 is totally different from that of A. melanoxantha and is more in the 

 style of A. cabira. 



Fore wing. Upper surface black, with two rows of oblong white 

 spots : one row about the middle of the wing consisting of three 

 dissociated spots, one in the middle of the cell, a second below the 

 base of the second median nervule, and the third near the hind 

 margin below the first median nervule. The second row of white
