Teraco/us ephyia is distinguished from T. evanthides by having the dark transverse 

 line on the primaries more distinct and not broken up as in the latter species. 

 Scarcely any suffusion of yellow is visible. 



Male. — Central area of the primaries creamy- white, faintly dusted with grey at 

 the base; the orange apical patch very bright in colour, narrowly edged along the 

 costa, and on the apex and hind-margin with brownish-black to as far as the first 

 median nervule ; the brownish-black transverse band is broader, with a slight suff'usion 

 of pale yellow ; the usual minute black dot is visible at the end of tiie discoidal cell. 

 Secondaries entirely creamy-white ; the nervules terminating in black hastate spots on 

 th(! hind-margin. 



I nderside. — Ground colour of tiie primaries whitish ; the apical area pale yellow ; 

 the base greenish-yellow, extending to the discoidal cell ; the black dot at the end of 

 the cell strongly marked. Secondaries white, with a greenish-yellow shading on the 

 hind-margin ; the usual minute black dot in evidence at the end of the cell. 



Expanse 1-3 inches. {Spue, e.r " Upper Eyypt" ; Coimd Pefherick ; Mm. Brif.) 



Female. — Central area of the jjrimaries creamy-white ; the orange apical patch 

 not quite so bright as in the male ; the costa, apex, and hind-margin dusty-brown to 

 as far as the first median nervule ; the dusky transverse band somewhat irregular in 

 outline ; the pale-yellow suffusion somewhat more distinct, and the minute black spot 

 at the end of the cell rather larger than in the male. Secondaries, general 

 colour creamy-white, the dusky-brown nervular spots on the hind-margin also larger. 



Utider-side. — Centre of the primaries white ; the base, costal margin, and apical 

 area pale yellow ; the usual black spot visible at the end of the cell ; no other spots 

 or markings indicated. Secondaries creamy-white ; hind-margin and nervules 

 yellowish-green ; the usual black dot present at the end of the cell. 



Expanse 1-4 inches. {S2jec. loc. u/n., Godman-Salvin Coll.; Mus. Brit.) 



" Dry-season " form of Male. — Central area ot the primaries yellowish-white ; 

 the orange apical patch somewhat brighter in colour ; the black markings much 

 reduced and almost obsolete ; the •'^l?..?k transverse line likewise indicated by a tew 

 faint streaks; the pale yellow line more strongly marked than in the ' wet-season"
