188 MISS E. M. SHARPE ON NEW [Mar. 3, 



ochreous between each nervule. From the costa, near the apex, is 

 a row of uhie ovate yellow spots forming a transverse band down to 

 the inner margin, the spots distinctly separated from each other by 

 a line of brown, marking each nervule ; the spots on the disk below 

 the radial and median nervules being much larger. Between 

 the second and third subcostal nervules, and situated at the base of 

 these two nervules, is a small hastate spot, smaller in size than in 

 P. constantinus and nearly obsolete. 



Sind wing. Similar to the fore wing in colour and markings, the 

 transverse band of ochreous spots being continued in the same line 

 as on the latter ; the hind margin similarly scalloped with a fringe 

 of ochre between the nervules, the tail being scalloped on the inside 

 only. 



The ochreous markings on the hind wing are more longitudinal in 

 form than on the fore wing : those of the disk are in the form of longi- 

 tudinally-ovate twin spots, between which is a scarcely visible line 

 of brown ; the spot near the anal angle very small and rounded. 



Underside. Resembles the upper surface in general character of 

 its colour and bands, but the transverse band on the hind wing is 

 of a pearly appearance. 



The general colour of the under surface is dark brown, but there 

 are irregular mottlings of lighter brown on the basal area of the 

 hind wing, causing the darker brown ground-colour to take the 

 form of a baud in continuation of the ochreous band, which does not 

 extend higher than the second radial nervule. 



Exp. 4g inches. 



Hab. Between Sotik and Kavirondo, Oct. 1889. 



The female is very similar to the male in colour, but the ochreous 

 markings are larger, especially on the hind wing, where they form a 

 broad band composed of entire (not twin) spots, which are obtusely 

 oval towards the base of the wing and scalloped towards the hind 

 margin. 



Exp. 4| inches. 



Hab. Kikuyu, August 1889. 



2. Papilio jacksoni, sp. n. (Plate XVII. figs. 1, 2.) 



Nearest to P. cynorta of Fabricius, but differing in the white 

 band of the fore wing, which, instead of being continuous with that 

 of the hind wing, is broken up into spots. 



General colour black, with white bands, spots, and markings. 



Fore wing. Hind margin obsoletely scalloped with a white fringe 

 between the nervules, a transverse row of eight spots slanting from 

 the apex towards the inner margin, those between the radial and 

 median nervules much smaller and more hastate in shape than in 

 P. cynorta ; the submedian spot of white consisting of a twin spot 

 longitudinal in shape. Below the discoidal cell, the areas of the 

 wing adjoining the nervules are marked by a shade of ashy brown, 

 the texture of the wing at the same time being hirsute. 



Hind wing. Hind margin distinctly scalloped with white between 

 the nervules ; a submarginal row of five white spots, rounded in
