NOVITATES ZOOLOGICAE XXIII. 1916. 275 



Bitye, Ja River, Cameroons, April — June 1910, lesser veins (G. L. Bates), 

 type c? in coll. Tring Mus. Several others (both sexes) from the same locality, 

 coll. Tring Mns. et coll. L. B. Pront. 



Subfamily HEMITHEINAE 

 8. Pingasa hypoxantha spec. nov. 



c?, 47-51 mm. Head whitish, the face and npperside of palpus mixed with 

 ochreons. Collar and patagia ochreons, thorax and abdomen mostly whitish. 



Forewing white, with scattered rufons-ochreous, more or less black-mixed 

 scales; lines formed of accumulations of the same scales, sometimes (especially the 

 postmedian) much more strongly black-mixed ; antemedian placed as in most of 

 the genus, angled outward in and again behind the cell, rather variable, the angles 

 generally moderate or rather sharp; discal mark distinct, elongate ; postmedian 

 line from costa midway between antemedian and apex, with small outward teeth on 

 the veins, oblique outward to R 1 , here slightly angled, from R 1 forming a broad, 

 shallow outward curve, somewhat incurved behind M 2 , reaching hindmargin midway 

 between antemedian line and tornus,or nearer the former; subterminal line strongly 

 dentate, feeble, indicated by weak rufous or greyish proximal shading ; terminal 



line slight, waved, thickened into clots between the veins ; fringe unspotted. 



Hindwing with the cell-mark smaller, weak, sometimes obsolete ; postmedian line 

 curved almost parallel with termen, the outer teeth strong ; the rest as on forewing. 



Both wings beneath white, at the base shaded with bright yellow, which some- 

 times extends to the middle of the wing and even shows itself in isolated spots 

 against the dark borders. Forewing with cell-mark strong; a blackish, not very 

 intense terminal band, enclosing a white apex ; extending from costa to R 3 and 

 often with a narrow submarginal extension to M 1 or M 2 ; terminal dots present, 

 variable in strength. Hindwing with cell-mark weak or wholly wanting, dark 

 border restricted to confluent or isolated spots on R 1 and R 2 , and sometimes small 

 isolated ones on M 2 and SM 2 . 



Rau, Nandi Country, February 23-24, 1899 (Dr. Ansorge), 12 <$ 3 in coll. 

 Tring Mus., determined by Warren as rhadamaria Guen., to which variable species 

 it bears much resemblance on the upperside (though the outward sweep of the 

 postmedian line is differently formed), but which has a deep black band on the face 

 and clear white underside with extended black borders. 



As subsp. holochroa I describe a form from Bopoto, Upper Congo, 1898 

 (Rev. K. Smith), in which the upperside is more strongly marked, more shaded 

 with rufous proximally to the subterminal line, and with grey distally hereto, the 

 undersurface almost entirely orange-yellow, with an interrupted black border, con- 

 taining on the forewing merely some small white spots at apex, midtermen and 

 near tornus and on the hindwing a very narrow, in place's interrupted, white distal 

 margin. Type in coll. Tring Mus. 



9. Comibaena rufitornus spec. nov. 



S , 28 mm. Head green, the face sprinkled with red on sides and lower part, 

 the palpus white, strongly mixed with red except at base. Antenna whitish, the 

 shaft with a few reddish dots proximally; pectinate to the twenty-iifth joint (in 

 leucospilata to the twenty-third). Thorax above green, abdomen with a reddish-
