18 Miss A. E. Piout on some 



subtermina], wliicli is faintly visible as a pale streak on costal 

 half ot' the apical dark patch, then represented by pale dashes 

 on the veins ; fringe purple-brown, paler between M- and 

 tornus. 



Hind wing nearly uniform grey-brown, with a pale 

 terminal line, a pale subterminal dash from about M^ to 

 tornus and the fringe paler from behind SC" to R^ and from 

 M~ to tornus and outer one-fourth of abdominal margin ; 

 fringe with a pale central line. 



Underside of both wings gre^'-brown, the distal third 

 tinged with chocolate-brown. Fore wing with five white 

 spots on apical part of costa, a dark, distally pale-edged 

 postmedial line, almost obsolete behind E^, an indistinct, 

 dentate, pale subterminal line and bluish-white shading on 

 distal margin and basal half of fringe, especially on apical 

 half of wing. Hind wing with faint, pale postmedial and 

 subterminal lines and bluish-white shading on termen and 

 fringe from behind SC^ to tornus.

This species is extremely near to P. conjunctura, Wlk., 

 from Sierra Leone, but the distal margin of the fore wing is 

 distinctly more rounded, the under surface is more sharply 

 marked, the general tone of the fore wing is somewhat more 

 leaden, and conjunctura has the inner half of the medial area 

 of fore wing pale, the outer half bordered by a strongly 

 curved, distinct line, instead of the two areas almost shading 

 into each other, as in diffusa. The Rev. C. R. N. Burrows, 

 who has examined the genitalia of the two species, writes : 

 " I consider (these) distinct species. The difference in 

 detail is very marked indeed, although in general form the 

 suggestion is close affinity. The (?furca) is quite different. 

 So is the costal arm.^' The genitalia are figured on 

 PI. VII. : P. conjunctura, fig. 2 ; P. difusa, fig. 3. PI. VII. 

 figs. 4, 5 represent P. humilis and isotima [see Ann. & Mag. 

 Nat. Hist. (9) iii. p. 185 (1919)].
