 Distal margin (if ibrewing entire, apex produced, inner margin sinuate before angle, 

 this produced backwards ; stalk of >S('- and II' of hindwing rather long, D- twice 

 as long as ])■', somewhat angled, very oblique, D' e(|ualling 1)'. Eighth tergite 

 truncate. Vagiiuil jilate (PI. XVIII. f. 14) characteristic, the antevaginal part 

 Qir])^ membranaceous, folded; at each side of the vaginal orifice (I') there is a 

 strongly cliitiniscd ridge, continued mesiad, ending in front of the orifice, produced 

 into a long, curved, horn-like process (/), which is generally visible in the specimens 

 without dissection ; the edge of the ridge irregularly denticulate. 



The scales at the edge of the last stigma of the abdomen are white, forming 

 a rather conspicuous sjiot. Forewing without basal dot. Mid- and hindtibia with 

 a white spot at the base.

Agrees closely witli pinjuniii jti/i/ur<i(i in the shajie of the wings, but differs as 

 follows : 



? . Head and thorax with a darker brown ill-defined middle stripe ; the 

 posterior abdominal stigmata with a very few white scales, the last stigma-spot 

 much smaller than in pi/gnrf/a. Forewing with a dark browu subbasal spot. Hind- 

 tibia greyish white above from base to apex. Vaginal armature (PI. XVIII. f. 13) 

 very diflerent from that of pi/garga ; the jiostvagiual plate {pvp) small, triangular, 

 sunken ; before the vaginal orifice there is a high triangular ridge (c/ryj), which ends 

 iu two irregular points. 



S . A S in the Staudinger collection, also from the Cameroons, belongs perhaps 

 to this species ; it is nearly as grey as (/rai/i ; the harpe has a long, cylindrical,
