African Species of the Gemts Acraca. 165 



tuwards margin. F.-w. apiciil black and li.-w. hind-marginal 

 border a little broader than in ^ . 



Thorax and abdomen black above with white markiii'fs. 



A. pudorella detecta, snbsp. 



^. Expanse 48-54 mm. Closely resembles A. cahJarena. 

 Wing.s rather thinly scaled. F.-w. reddish oclireous to rusty 

 red at base becoming distinctly paler beyond end of cell. A 

 slight dusky suffusion at base and along costa, and a black 

 apical tip 5 to 7 mm. broad, the inner edge of which is usually 

 less well defined than in c(ddarcna. The spots are rather 

 variable and usually much reduced. One in cell above origin 

 of 2, a black mark on upper part of discocellulars. Beyond 

 cell a discal row of five (some often absent) in a straiglit line 

 at right angles to costa. One in 2 near median, one beneath 

 this in lb, but nearer margin, and occasionally a subbasal spot 

 in the same area, near median. In some examples traces of 

 submarginal spots in lb and 2. 



H.-w. with a slight black basal suffusion and a narrow black 

 hind-marginal border formed of a series of arches on a marginal 

 line enclosing more or less distinct spots of the ground-colour. 

 The inner edge of this border is often rather suffused. The 

 spots of the h.-w. up])erside correspond to those beneath, but 

 those near base and inner margin are frequently only faintly 

 indicated. 



Underside f.-w. ground-i/olour as on uppei\side but thinly 

 scaled and shiny. Apical black replaced by greyish ochreous. 

 A black spot at base of costa, other spots as on upperside. 

 H.-w. pinkish ochreous with a few reddish marks near base. 

 Marginal border formed of black arches on a thin marginal line, 

 enclosing whitish internervular spots. Black spots as follows : — - 

 Discal series, one in 7 about middle, one in 6 nearer margin, 

 one in 5 still nearer margin, and more distally jilaced than in 

 caldarena. One in 4 slightly removed from end of cell. One 

 in 3 about midway between end of cell and marginal border, 

 one in 2 touching median and 2, and distinctly more proo:im,(dly 

 placed than in caldarena. A spot in Ic nearer margin than 

 that in 2. One in lb on a level with that in 2. A spot in 

 8 near precostal, a subbasal in 7, two in cell, one at base of 

 5 on m.d.c, a basal and a subbasal in Ic, the latter contiguous 

 with a spot in lb, close to which is a spot in la. Also a 

 subbasal spot in la, and some irregular black about the bases of 

 the nervules. 



Head black with a pale line between the eyes, and two tufts
