PSEUDALETIS MAZANGULI, Sp. 11. (Plate II. fig. 6, $ .) 



Creamy white with black markings. Allied to zebra Holl. 

 2 . Upperside. — Primary. The ground-colour creamy white ; 

 costa dusky ; base of wing dusky, narrowly so toward hind margin ; 

 a black band across middle of cell to median ; a second black band 

 across end of cell to vein 2, filling up angles formed by median 

 and veins 2 and 3 ; a third black band from costa bej^ond end 

 of cell to vein 3, where it becomes confluent with outer margin ; 

 a broad dusky outer margin from apex to posterior angle, where 

 it is especially wide and black in colour. 



Secondary. Creamy- white ground, with traces of underside discal 

 row of spots in areas 2, 3, 4. A well-defined median black outer 

 margin enclosing three small creamy-white spots at anal angle ; 

 black tails on 1 and 2, of which the former is the largest. 



Underside. — Primary. As upperside but outer margin nar- 

 rower, at apex enclosing a narrow whitish line ; at posterior angle 

 much invaded by creamy-white ground-colour leaving only a mark 

 like a ? in area 1 b. 



Secondary. Ground-colour as upperside ; a black streak extends 

 from base along area 1 b for half its length and then turns sharply 

 to inner margin ; a discal line of confluent spots from costa ending 

 in a narrow streak in area 2 ; black outer margin broken up into 

 narrow marginal and submarginal lines enclosing band of ground- 

 colour, flushed with ochreous on nervules 2, 3, 4 and in area 2. 

 Anal lobe broadly covered with black scales enclosing a marginal 

 and narrow submarginal line of silver ones. 



Fringe dusky ; patyri, which are very small, ochreous ; abdomen 

 banded black and white, in mid-ventral line a well-defined 

 ochreous streak from head to anus. 



Length of primary 25 -5 mm. 



Type 2 in British Museum. Mazanguli's S. Kaluli river, 

 Lualaba valley, Katanga, 23.iv.07. 



This species seems most nearly allied to P. zebra Holl., but 

 differs in many points as regards the distribution of the black 

 markings. 



Hypolycjena hatita Hew. 



This species occurs over a wide area, but is nowhere common. 

 I found it least rare on the upper Kafue river, x., and in the 

 same month on the lower Chambezi and Lake Bangweolo. It 

 usually frequents the edges of patches of forest, generally high up 

 in the trees, making it difficult to catch. 



Hypolycjena liara H. H. Druce. 



Occurs sparingly over a wide area. The females are scarce. 

 Has somewhat the same habits as the last species. 



Hypolyc^na philippus Fabr. 



This is a common species almost everywhere.
