eud. Abdominal tergites with weak spines all over, the spines dense at the edges. 

 Distal margin offorewing entire, apex prodneed, inner margin sinnate before angle, 

 this produced backwards ; stalk of SC- and R' of hindwing rather long, D- twice 

 as long as D', somewhat angled, very oblique, D' efjualling BK Eighth tergite 

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

 ('irj}) membranaceous, folded; at each side of the vaginal orifice (!') there is a 

 strongl)' chitinised ridge, continued mesiad, ending in front of the orifice, prodneed 

 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 consjiicuous sjiot. Forewing without basal dot. Mid- and hindtibia with 

 a white spot at the base.

? . Distal margin of forewing convex between R- and hinder angle. Body and 

 wings more ])inkish above than in the West African form, underside washed with 

 brick-red ; longer scales of fringe of hindwing white. The ridge connecting, in

One ? in coll. < "harles Obertbiir. 



This is one of tlie instances of the East African form having the distal margin 

 of the forewing more convex than the West African form. 



a05. Polyptychus affinis spec. nov. (PI. 1. f 13, ?). 



Agrees closely with jijigarya /ii/yaiya 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/(/ai-(/a. Forewing with a dark brown subbasal spot. Hind- 

 tibia greyish white above from base to apex. Vaginal armature (PL XVIII. f- ^A) 

 very different from that of pyynr-ga ; the jiostvaginal plate {j'vp) small, triangular, 

 sunken : before the vaginal orifice there is a high triangular ridge (rrry.!), which ends 

 in two irregular points. 



d". A t? in the Staudinger collection, also from the ('ameroons, belongs perhaps 

 to this species ; it is nearly as grey as yrayi ; the harpe has a long, cylindrical, 

 pointed, horizontal process which j)rojects beyond the end of the clasper ; there
