CIREOCHROA. AKGYNNIS. 429 



the subterminal line is distinct. Hind wing much as in the 

 dry-season specimens of a oris, with the discal and subterminal 

 markings also obsolescent. Underside similar to that in aoris, 

 but the inner margin of the pale discal band crossing both fore 

 and hind wings is nearly straight, not highly sinuous, and the 

 outer margin is very sharply defined by a dark line ; the apex of 

 the fore wing is wiiite, as in aoris, but the black on the apex and 

 on the termen on the upperside shows through as a dark, almost 

 brownish terminal band. — 2 • Upperside differs from the typical 

 form conspicuously in the broad white transverse discal band 

 confined to the fore wing ; on the hind wing the space between 

 the transverse black line limiting the basal area and the postdiscal 

 series of slender lunular black markings is of the same shade as 

 the ground-colour of the wing, except that the discal black line is 

 anteriorly bordered on the outer side by a small white patch. 

 On the fore wing, the inner margin of the white discal band is 

 bordered by a broad black line, and the apex and termen, beyond 

 its outer margin, are broadly dusky black. Underside purplish 

 white ; the markings somewhat as in the 3 , but the white discal 

 band on the upperside of the fore wing shows through by trans- 

 parency, and the discal band on the hind wing is pale blue; the 

 dark line defining the band on the hind wing crosses also the fore 

 wing and is prominent on both wings ; the markings beyond the 

 discal band on the hind wing are suffused with pale blue.
