on the sides. Tegmina hyaline with reddish nervures ; hind 

 tibiae rather hairy, with eleven teeth on the outer edge. 



Four specimens (1 c? , 2 5 , 1 nymph) from Baringo, Dec, 20, 

 1899. 



There are several closely allied species from East Africa, of 

 which one only (P. alierna1.a Schulthess, nee Brunner) has 

 hitherto been described.

Fifteen specimens, Baringo, Dec. 20, 1901. 



None of these specimens exactly agree with the unique type of 

 the species, which is, besides, in rather poor condition ; . but they 

 vary so much among themselves that I cannot consider them 

 distinct. The males have indefinite longitudinal dusky markings 

 on the head and thorax (chiefly on the sides) as in Walker's type ; 

 but the latter has the outer central area of the femora much 

 more completely filled up with blackish than in any of tie 

 Baringo males, which have only isolated and variable blackish 

 patches on that area, the largest towards the extremity. In the 

 female there is a broad blackish band running backwards fi'om 

 the eye, over the sides of the pronotum, and a portion of the 

 tegmina, and more or less distinctly bordered above and below by 

 yellow lines. The central area of the hind femora is filled up 

 externally in its vipper half with a black stripe, broken into three 

 parts, and is bordered on the upperside above by two longer and 

 narrower black stripes.

Exp. al. 80 mm. ; long, corp. 36 mm. 



Female. Rufo-testaceous ; carina of the pronotum very slightly 

 raised, subobsolete behind, hinder half set with lai-ge granules, 

 and shoi'ter and more rounded behind than in Ilumbe tenuicornis 

 Schaum. Tegmina with two oblique brown bands, the first at 

 one-quai-ter of the length, and the second, much narrower and 

 less complete, about the middle, bounding the outer subhyaline 

 area. Costal area spotted with bi-own, especially about the 

 first brown band. Beyond the lower extremity of the narrow 

 outer band a series of linear blackish marks runs along the 

 inner margin. Wings greenish yellow (possibly bright yellow in
