Ar, several mm broad, the second lietwocn JI' and .SM-, the two sejjarated ov coii- 

 tigiioiis ; two equally iudistiuet aud ill-defined bands or traces of snch on disc, the 

 external one more or less dentate, widened at costal margin, here inelnding a white 

 Innule (wliieh stands reall_v at the jiroximal side of the dentate line proper) ; the 

 marginal area partly or almost totally filled np with brown sealing, especially 



between R- and M-, this brown area absorbing more or less tlie dentate line. 



Hindwing : the tawny red speckles large, becoming blackish brown at the abdominal 

 mar<;-in, the two bands formed by the speckles broad, the external one not always 

 distinct. 



rndrrsidc : speckles of both wings large. -Forewing : bands as above, bnt 



those in the basal half red : snbapical white jiateh larger than above, more scjnare ; 



fringe black at ends of veins. Hindwing : discal band not tonching lower angle 



of cell, abont 'J mm. broad : the others nearly jiarallel to margin, not concave beyond 

 niiitdle : costal margin more than twice as long as abdominal margin. 



J. Abdomen open behind owing to the peculiar development of the claspers. 

 Tenth tergite (PI. XL. f. 11, ventral view) broad, sinuate, lobes rounded ; sternite 

 broad, strongly narrowed to apex, which is truncate, middle of sternite sunken. 

 (_'las])er (PI. XL. f 8) : dorsal margin produced distally into a long process which 

 is armed with thin acute teeth ; ventral part of clas]ier reduced, rounded, densely 

 clothed with sniall scales ; a snbbasal rather sliglit fold, and another fold situated 

 more distally beset with bristles ; harjie represented by a long ])ointed process ; the 

 processes of the two harpes close together. Penis-sheath (PI. XL. f 14) short, 

 stout, curved, ending in a short process which appears clubbed in side-view, but 

 is compressed and therefore pointed in dorsal view. 



¥. Vaginal plate (Pi. XVIL f. '2) larger than in the other species ; vaginal 

 orifice (T') on a kind of postament which is compressed to a ridge at each side, 

 the ridge truncate with the angles projecting : behind this elevated structure there 

 is a deep cavity the hinder (or upper) wall of which is formed by the large, strongly 

 chitinised, post vaginal ])late (y;*-/;), this plate mesially carinate within the cavity, 

 and transversely rugate or folded distally. 



]l(ih. Congo basin and East Africa : its range extends proliably farther north.

?. ^Vings comparatively sliorter and broader than in the other species ; body 

 and wings paler, 



AVings, iijtpcy«i(-lc, speckles sj)arser, on hindwing in size midway between 



those of constrij/ilis and stit/matiai. Forewing: hinder angle less rounded; 



subbasal line indicated by an oblique indistinct line in cell in front of base of M' ; 

 a line in apex of cell, broader than in constvi(/ilis, much narrower than the respective 

 patcii in s^/yw^/w, forming as in the latter species an obtuse angle with IP, a short 

 elongate costal mark at base of fork indicating a discal line, another narrower mark 

 hallway to apex, a brown apical patch, sharply defined behind, wiihin it a trace of 

 the white spot of the other species ; speckles somewhat denser in marginal area 



between !{• and M- and along W. Himlwing: abdominal margin jialer than in 



the other species, with few speckles : the inner discal band vestigial, nearly straight, 

 the second and third ^iresent in cona/ru/ili.i not marked.
