Race agoranis. Grose-Smith. Differs from typical agottina as 

 follows : $ . Upperside, fore wing : apical third to nearly apical 

 half shaded with diffuse black scaling ; the curved series of spots 

 of the white ground-colour so conspicuous in agostina present, but 

 more or less blurred. Hind wing : terminal margin with very 

 diffuse dusky-black spots at the apices of the veins. Underside, 

 fore wing : the black edgings to the A'eins very diffuse. Hind wing 

 a much paler yellow than in typical agostina ; the terminal dusky- 

 black border as in the typical form but broader, the black scaling 

 more diffuse. $ . Upperside : very similar to $ agostina, but the 

 dusky-black colouring on both fore and hind wings less pronounced ; 

 the cell and greater part basally of the interspaces with the white 

 of the ground-colour more conspicuous. Underside : as in 

 agostina, but the yellow on the hind wing paler, the dusky-black 

 terminal border broader, inwardly not well-defined, the superposed 

 white spots blurred with black scaling and diffusely spread inwards. 

 Antennae, head, thorax and abdomen as in typical agostina. 



Exp. <5 $ 78-81 mm. (3-08-3-19").

c? . Upperside : dusky brownish black to black. Fore wing with 

 the following diffuse white markings : Cell with an oblique sub- 

 apical bar, an angulated discal series of three upper spots inclined 

 obliquely outwards and three lower spots inclined obliquely 

 inwards ; in most specimens the oblique bar in the cell and the 

 lower two of the discal series of spots are extended diffusely 

 inwards ; finally, a subterminal series of large rounded spots white 

 inwardly, irrorated with black scales outwardly. Hind wing : 

 dorsal margin, including interspaces la, 1 and 2, basal half whitish, 

 apical half more or less strongly tinged with pure canary-yellow ; 

 a large oval yellow spot at base of interspaces 7 and 8 ; a broad, 

 ill-defined diffuse whitish streak in cell ; a discal series of diffuse 

 whitish spots that is angulated outwards at interspace 5, the 

 posterior spots more or less tinged with yellow ; followed by a
