TERACOLUS. 59 



Primaries with the dark basal area thickly sprinkletl with grey ; an oblong 

 blackish spot situated above the sub-median nervure near tlie centre of the inner 

 margin ; the orange apical patch larger than in 7'. bctlonl; the apex, hind-margin and 

 sub-apical line brownish-black in colour, and with two adjacent vermilion spots 

 situated in the paler orange area of the apical portion of the wing. 



Secondaries with the dark nervular spots on the hind-margin smaller than in 

 T. befioni, those near to the inner margin sprinkled with grey and gradually becoming 

 obsolete ; the transverse discal line only faintly indicated. 



Underside. — Excepting tliat the black markings are smaller and only faintly 

 marked, the lower surface of this species is similar to that of T. betfoni. 



Expanse 2"2 inches. {Spec. e.v. Lake Ni/asa ; Godincai-Salvin Coll.; Mica. Brif.) 



A white form of the female in Mr. Rothschild's collection (Fig. 1) only differs from 

 the one above described in having white on the apical area instead of orange ; the 

 brownish-black markings of the fore- wing are somewhat more heavily indicated, and 

 the nervular spots on the secondaries are larger, but distinctly separated. 



Underside. — The apex of the primaries pale ochre ; the sub-apical row of black 

 spots larger and more strongly marked than in the orange-tipped form. Secondaries 

 pale ochre, the transverse discal band dai'ker and plainly indicated. 



Expanse 2 inches. {Spec. ex. Belagoa Bay ; Mns. Bofhschihl.) 



"Dry-season" form of Male. — Smaller than the "wet season" form, with the 

 primaries creamy white, the nervules being also whiter and less distinct ; the purple 

 apical patch smaller, brighter in colour and enclosed on the inner edge by a narrow 

 black line, the apex reddish-brown tinged with grey. Secondaries creamy white; the 

 blackish nervules scarcely indicated. 



Underside. — Central area of the primaries white; the apex sandy pink sprinkled 

 with light brown vermiculations. Secondaries entirely sandy pink, thickly vermicu- 

 lated with light brown ; a distinct brown transverse band crossing t)ie discal area; a 

 minute brownish spot at the end of the cell. 



Expanse 2 inches. [Spec. ex. Shire Biver; Godman-Sahin Coll.; Mas. Brif.) 



" Dry-season " form of Female. — General colour of the primaries pale yellow, 

 becoming somewhat deeper towards the brilliant orange apical patch ; the apex 

 brownish, a sub-apical row of dark brown crossing the orange jjatch, which is bordered 

 on its inner aspect by a further interrupted narrow line of brownish-black ; a 

 yellowish -green shade overspreading the area of the cell, with the usual black spot at 

 the end of the latter. Secondaries entirely pale yellow with only four nervular 

 spots on the hind-margin more or less faintly indicated. 



Underside. — Primaries pale yellow, the orange on the apical area relieved by a 

 sub-apical row of five brownish spots ; the basal area sprinkled with grey.
