COLIAS lY. 



COLIAS KEEWAYDIX, n. sp. 1—9. 



Male. Expands from 1.6 to 1.8 inches. 



Ujiper side sulphur yellow, the disk of both wings more or less tinted with 

 orange, which occasionally has an oi)aline reflection ; on primaries the orange is 

 deepest next base and on inner margin, towards hind margin insensibly passing 

 into yellow ; on secondaries the tint is less deep, extends quite up to the marginal 

 border but fades into yellow towards costal and abdominal margin ; base thickly 

 powdered with black which extends a little way along inner margin of primaries, 

 and, on secondaries, covers part of the cell and median interspaces; discal spot of 

 primaries black, sub-ovate, often much compressed, but sometimes almost circular ; 

 marginal border black, of median width, crossed at apex and often throughout by 

 yellow nervules ; regular on its inner edge, with a slight projection on sub-medi- 

 an and an indentation below that nervure, not quite parallel to the margin in its 

 general course, but approaching it somewhat near the disco-central ; beyond this, 

 curving roundly towarils costa and terminating (usually quite abruptly) on costal 

 edge at about one-fourth distance from apex to ba^sc ; on inner margin projecting a 

 short, attenuated spur. 



Secondaries have the discal spot deep orange, occasionally with a small atten- 

 dant sjwt on its anterior edge ; the marginal border narrowed, usually regular, but 

 sometimes a little excavated between the nervules, commencing above the upper 

 branch of sub-costal and ending acutely at or a little beyond the first branch of 

 median ; fringes yellow, edged slightly without by roseate, more decidedly at apex 

 of primaries. 



Under side uniform deep yellow ; costal edges and fringes roseate ; costal mar- 

 gin of primaries and the whole of secondaries much sprinkled with fine black 

 scales ; discal sjiot of primaries sub-ovate, sometimes triangular, black, with a dot 

 or streak of yellow, or sometimes white, in the centre ; the sub-marginal row of brown 

 spots faint, consisting of but a few scales and partly obsolete ; secondaries have a 

 similar row of spots, a small elongated patch on costa and a roseate sjiot at inser- 

 tion of median ; discal spot large, margaritaceous, in a narrow brown ring about 

 which is a paler halo ; the attendant spot, if any, a dot in the centre of a 

 similar ring. 



Body covered with yellow-grey hairs which are tipped with faint roseate on 

 the collar ; abdomen black 2')artly covered with yellow scales, beneath yellow ; tho-
