Exp. al., {$) I in. — i in. 3 lin. ; ($) i in. 3-4^ lin. 
Orange-yelloio, not metallic, luith hlack spots; base of both ivings 
broadly blackish and densely blue- scaled ; hind-wing of $ richly shot 
with a shifting blue lustre. Fore-wing : costa and hind-margin bordered 
with black ; costal border broadest near base, where it is powdered 
with fulvous-ochreons, but usually much narrowed beyond middle ; hind- 
marginal border very regular, of even width, very slightly crenelated 
on inner edge ; just beyond basal clouding a small round spot in dis- 
coidal cell, a longer quadrate spot closing cell ; beyond middle an 
irregular row of six spots, of which the three first form a continuous 
costal stripe, the fourth is nearer base, the fifth in a line beneath the 
three first, and the sixth (above submedian nervure) in a line beneath 
the fourth. Hind-iving : a row of six spots as in fore-wing, except 
that the three first spots are more separate, — in $ the first spot is 
almost merged in costal blackish band, which is wider than in $ ; on 
hind-margin a row of black arches (sharper in ^) intersecting the 
ground-colour between nervules, which carry the orange to edge ; 
closing cell is a black streak usually merged with basal clouding. 
Cilia fuscous mixed with white ; in hind- wing mingled with red. 
Under side. — Costa and apex of fore-iving and whole of hind-iuing pale 
creamij-ferruginous. Fore-wing : two cellular spots and first spot of 
transverse row silver-centred ; a third black dot near base in cell, 
and another (silver-centred) on costa beyond cell ; beneath central 
spot of cell a good-sized rouiided spot below submedian nervure ; close 
and parallel to hind-margin a row of fuscous spots, indistinct near 
costa. Hind-ioing : often almost spotless ; a pale glistening line clos- 
ing cell ; near it, towards inner margin, a pale dot ; a submarginal 
row of pale dots, sometimes replaced by a faint reddish line ; transverse 
discal row sometimes represented by spots barely distinguishable from 
ground-colour except by their fusco-ferruginous outlines. . 
From its allied congeners, Z. Zeuxo and Z. Chrysaor, mihi, this species is 
at once distinguished by its blue-giistening basal patches, while its entire out- 
line of M'ings and plainly-tinted under surface preclude its being mistaken 
for the angulated Z. Thysbe, Linn. In the two species first named, also, the 
ground-colour is metallic, strikingly so in Chrysaor. The width and evenness 
of the hind-marginal border of the fore-wings resemble the corresponding features 
in Zeuxo, Linn. 1
