under surface of the secondaries, the costal border and an interno- 

 median streak from the base only being saffron-yellow. Though 

 this may perhaps be a distinct species, there is not at present 

 sufficient material to warrant its separation on mere colour-characters 

 apart from marking. 



108. Belenois dentigera, sp. n. 



cJ . Belongs to the B. calypso group ; above white : the primaries 

 with blackish costal edge ; the subcostal furca widely blackish- 

 bordered ; five other blackish triangular marginal spots in a de- 

 creasing series ; three widely separated grevish dots in an angular 

 subapical series ; secondaries with four small black marginal spots ; 

 thorax greyish, abdomen white. Wings below white ; primaries 

 with black costal edge, a black dot on the lower discocellular veinlet; 

 five unequal black spots in an angular subapical series ; seven black 

 marginal spots at the extremities of the veins : secondaries very 

 faintly rose-tinted ; costal border orange on basal and apical thirds ; 

 an ill-defined orange basi-abdominal streak ; a black dot at end of 

 cell ; a submarginal series of seven unequal black spots and a mar- 

 ginal series of six. Expanse of wings 60 millim. 



Stazione Gadda, 10th February, 1884. 



Only one male of this very distinct species was obtained ; it comes 

 nearest to an unnamed male in the Museum collection from Angola.

110. Belenois SEVERiNA. 



Papilio severina, Cramer, Pap. Exot. iv. pi. 338. G, H (1/82). 



111. Belenois infida, sp. n. 



(S . Above like B. severina, excepting that it is a little smaller, 

 and has a distinct black bar, commencing with a cuneiform black 

 costal spot, at the end of the discoidal cell of primaries ; the border 

 of secondaries narrower and interrupted by larger white spots. 

 Below, the costal border of primaries is not yellowish, the ground- 

 colour of the apical area is considerably browner, this border narrows 

 abruptly from the second, instead of remaining wide to the first 

 median branch ; the secondaries have a whitish abdominal border 

 and all the veins and the outer border are widely rufous-brown, the 

 latter interrupted by the usual yellow spots. Expanse of wings 46 

 millim. 



$ . Extremely variable, the primaries either pinky white or 

 chrome-yellow with a black external border occupying from one third 

 to more than half the wing ; a broad oblique black bar across the 

 end of the cell, connected by black veins with the outer border, or, 

 in some examples, perfectly lost in it, a small costal spot of the 

 ground-colour alone remaining to show the point of union ; three.
