Male. — Expands 3.5 to 4.5 inches. 
Upper side usually bright yellow, but often pale, banded with black; costa of 
primaries black, dusted more or less throughout, and densely next base, with 
yellow ; a narrow band crosses the bases of both wings, and the abdominal mar¬ 
gin, and near the outer edge of the yellow discal area bends inward at an obtuse 
angle and meets the second band ; this rises on costa of primaries against the 
middle of the cell, and crosses both wings, is broad on primaries, but narrows 
gradually as it approaches the inner margin, and on secondaries becomes a 
slender stripe tapering to a line on the disk ; the third band crosses the outer 
part of the cell of primaries and terminates either at median nervule, perhaps 
projecting beyond this a cluster of scales, or passes on to the lower branch of 
median ; is often narrow, sinuous, but sometimes is a diffuse patch rather than 
a band ; the fourth lies mostly on the outer side of the arc, and varies in breadth 
and shape ; the fifth is sometimes narrow and reaches from costa to second 
sub-costal nervule ; but most often it forms a rounded knob to a club-like 
band which connects it with the hind margin and underlies the sub-costal ner- 
vure, and both knob and band are dusted with yellow ; the hind margins bor¬ 
dered by a common band, which varies much in width, and as a rule is much 
broader in examples from the south, though there are many exceptions; on 
primaries the inner edge of this band is either even, or it is slightly excavated in 
each interspace ; and through it runs a sub-marginal series of small yellow spots ;
