1910.] FROM NORTHERN RHODESIA. 63 



Lualaba valley, iv. and v., and a single male from the Bimkeya 

 river, north of Kambove, viii. 



Belenois pict a, sp. n. (Plate III. figs. 1 J , 2 J .) 



This species exhibits some points of resemblance with B. thysa 

 Hopff., in the almost evanescent discocellular spot to the primary 

 and the orange-yellow basal flush on the underside of that wing, 

 but on the whole seems to be nearest to B. theora DbL, in general 

 distribution of its markings. With the exception of theora, it 

 differs from all the truly African species of the genus that I can 

 find described, in the presence of an orange-yelloio discocellular 

 spot on the underside of the secondary. This character may, 

 however, be seen in B. grandidieri Mab., from Madagascar. Dr. F. 

 A. Dixey informs me of the interesting fact that in the case of 

 theora, the yellow discocellular spot is presant only in West Coast 

 specimens, not in those from the Congo. 



Type d , wet-season. 



TJppERSiDE.^-PHmary. Creamy-white, the base dusted with a 

 few black scales. A minute black discocellular line may or may not 

 be present ; costa narrowly black ; a well marked apical and 

 outer-marginal black area enclosing six internervular white 

 streaks ; this black margin projects inwardly in area 3, and is 

 continued to posterior angle by a large spot at end of vein 2 

 and a smaller one on vein 1. 



Secondary. Base and ground-colour as primary ; a submarginal 

 row of small internervular black spots, those in areas 4 and 

 1 c usually evanescent ; a marginal row of seven large black 

 spots on ends of veins, those on 7 and 1 b the smaller. 



Underside. — Primary. Ground-colour as upperside, the base 

 with an ochreous flush, sometimes of considerable extent ; black 

 apex replaced by a subapical row of four spots of which third 

 from costa is the largest, and by a marginal row of spots on ends 

 of veins extending to posterior angle ; a large submarginal spot 

 in area 3 (the largest spot on the wing) ; whitish ground- 

 colour of apex marked by internervular streaks of pale sulphur- 

 yellow. 



Secondary bears a costal streak of bright vermilion (occasionally 

 orange-coloured) ; base of wing flushed with orange, of varying 

 extent, radiating from base along internervular spaces, especially 

 marked in area 1 c. A tvell-marked orange-yelloio discocellular spot ; 

 marginal spot much as upperside, but submarginal row of spots 

 better developed and joined to margin by rays of orange -yellow. 



Fringes of both wings black with white patches on the inter- 

 nervular spaces ; palpi covered with white hairs tipped dusky ; 

 thorax and abdomen whitish. 



Length of primary 3T5 mm. 



Type d 1 i n British Museum, from 150 miles west of Kam- 

 bove, near the Lufupa river, xi. Cotypes in Hope Coll., Oxford. 



The dry- season male is a smaller insect, length of primary 

 27-28 mm. It has all the markings somewhat reduced, but is
