274 NOVITATES ZOOLOGICAE XXIII. 1916. 



Forewing very pale buff, fading to whitish ; costal margin black as far as SC ; 

 the usual black apical patch rather more obliquely edged than in libyssa Hopff., the 



contained white spots as in libyssa. Hindwing concolorous, the black border as 



in rather narrow-bordered libyssa, the contained white spots rather broader in the ¥ 

 than in the <?. 



Underside the same, except that the costal margin of the forewing is only very 

 slightly mixed with black. 



Nyassaland : Mlanje Plateau, 6500 ft., December 18, 1913 (type <J and 4 ? ?), 

 December 17, 1913, 2 ??; Mount Mlanje, December 23, 1912. All in coll. 

 Brit. Mus. ; collected by S. A. Neave. 



6. Cartaletis tenuimargo spec. nov. 



i?, 42 mm. Head and antenna black; pectinations moderately stout, about 

 twice as long as diameter of shaft. Body black ; tegula with a white spot ; meso- 

 and metathorax and abdominal somites each with a white dorsal spot; abdomen 

 also with ill-defined white lateral spots. 



Forewing slightly broader than in the allies, the costal margin being slightly 

 bulged just beyond the middle, the termen slightly less oblique, the tornus some- 

 what better defined ; ochraceous-rufous with a black apical and distal border ; this 

 is 6 or 7 mm. wide anteriorly, but with a very slender proximal continuation for a 

 short distance along costa, narrows rather rapidly (the ground-colour making a 

 curved outward sweep behind R 2 ) and ends in a point at submedian fold ; enclosed 

 are a rather narrow white patch from SC 5 nearly to R 3 , a very small spot midway 



between R 3 and M 1 and a dot between M 1 and M 2 . Hindwing concolorous, with a 



very narrow, unmarked black border, near apex scarcely 2 mm. wide, for the most 

 part scarcely 1 mm. 



Underside the same. 



Kwidgwi Island, Lake Kiwu, 1500-2000 m., November 1907 (R. Grauer). 

 Type in coll. Tring Mus. 



Superficially — on account of its small size and the lack of white spots in the 

 border of the hindwing — more like Mesomima (section of Terina ?), but the vena- 

 tion is typically that of Cartaletis, except that the connecting bar between C and 

 SC of the hindwing is obsolete, though these remain farther apart than in the 

 Bracca group. Abdomen not very robust (section Leptaletis). 



7. Cartaletis gracilis variegata subsp. nov. 



Differs from name-typical gracilis (Sierra Leone and Gold Coast) in that the 

 ochreous markings are more deeply and brightly coloured (tawny or inclining to 

 rufous) and commonly much extended. In gracilis gracilis there is no ochreous 

 colour on the hindwing, on the forewing there is often only the ill-defined basal 

 patch, while the additional markings, when present, consist of at most two small 

 patches (much oftener one only) in the black apical patch proximally to the white 

 spots ; in^. variegata the basal patch is extended, better defined, continued on the 

 hindwing (though here usually small), the two tawny spots in the black border 

 are rarely absent, often confluent and not rarely extended into an interrupted or 

 continuous tawny band across the wing. Sometimes also the veins are in part 

 blackened.
