Ppjmaries much produced, costal margin strongly arched, hind margin straight 
or concave; tails long, narrow, and as in Zolicaon ; the sexes alike in color and 
markings. 
Male. —Expands from 3.5 to 4 inches. 
Upper side of primaries black, marked and spotted with bright yellow; of 
secondaries, bright yellow from base to marginal border ; primaries have a sub¬ 
marginal row of eight spots, equal, mostly rounded, and a discal series of eight 
which form a transverse band; above them a long patch of yellow scales, and 
a little within this, towards base, a subovate spot, truncated on apical side; the 
first discal spot is deeply and roundly excavated on anterior side; the second is a 
little shorter than first, and third still shorter, after which there is a gradual in¬ 
crease in length, to the seventh, which is broad and sub-rectangular; the eighth 
is narrow and marginal; at the extremity of cell within is a sub-lunate trans¬ 
verse yellow spot and a broader one in the middle, of irregular shape, the two 
being separated by a black space; the basal area thickly dusted with yellow 
scales. 
Secondaries have a broad black marginal border, which incloses a series of six 
yellow lunular spots, the first, at outer angle, small; above these spots are clus¬ 
ters of blue scales, never distinct, sometimes nearly all wanting; the inner mar¬ 
gin bordered with black, sometimes to median nervure, but in other cases very 
narrowly ; the anal spot small, yellow below, fulvous above, with a rounded black 
spot in the middle and which is connected with the narrow black edge of the 
margin; above the fulvous is a distinct blue crescent; tails of moderate length, 
narrow; fringes black, yellow in the interspaces. 
On the under side, the larger part of the marginal border of primaries is oc¬ 
cupied by a yellow band, and the remainder includes a nebulous stripe of dull
