Exp. aL, ($) I in. S^-io^ lin. ; (^) i in. 7^—9 lin. 
J Greenish-white, ivith a bright pearli/ hostre, most brilliant near 
bases of loing. Fore-ivi7ig : base blackish ; costa narrowly edged with 
blackish, wider so close to apex ; on hind-margin a row of black dots, 
lessening towards anal angle, one at extremity of each nervule, but 
none at extremity of submedian nervure. Hind-iuing : a series of 
seven minute black dots (rarely absent) along hind-margin, at extre- 
mities of nervules ; base more or less blackish. 
Under side. — Variable. Fore-wing : a very small black dot at 
extremity of discoidal cell ; costa narrowly^ a]oex broadly, tinged ivith 
very pale dull-yellowish, sprinkled more or less thichly with dark-grey 
dots. Hind-iving : entirely of the same pale-yellowish, thickly sprinkled 
with grey atoms ; costa at base tinged with pale bright green, and some- 
times faintly edged with yellow ; a distinct black dot at extremity of 
discoidal cell ; some dark-grey ill-defined spots near base, arranged 
transversely ; beyond middle, parallel to hind-margin, a band of about 
seven darker spots, commencing on costa with a rather conspicuous 
larger mark ; hind-marginal dots larger than those in fore-wing. (The 
grey irroration of the under side is often very thinly sprinkled, and is 
frequently altogether wanting in the central portion of the hind- wing.) 
% Bather wiore yelloivish than but loith the same pearly lustre, 
which is indeed considerably more extended in basal area of fore-wing. 
Fore-wing : a more or less distinct disco-cellular dot ; beyond middle a 
row of brownish spots parallel to hind-margin, consisting of three small 
spots forming a streak from costa almost to lower radial nervule, and a 
rounded larger spot between third and second median nervules ; occa- 
sionally a fifth indistinct diffused spot between first median nervule 
and inner margin ; sp)ots on hind-margin very much larger than in J, 
contiguous, someiuhat rhomboidal in form {in some instances almost form- 
ing a marginal stripe), the last spot on submedian nervure. Hind- 
iving : dots on hind-margin larger than in but not one-fourth the 
size of those in fore-wing; occasionally a row of spots beyond middle, 
similar to that on under side of ^, but not so distinct. Under side. — 
As in ^, but often with hind- wing and apex of fore-wing of a more 
decided yellow tint. Fore-iuing : the spots beyond middle faintly 
marked ; hind-marginal dots barely larger than in $ ; base faintly 
tinged with very pale greenish-yellow. 
In Boisduval's description of this species, the examples in which 
the under-side irroration is wanting or slight are typical, while those 
densely irrorated constitute his Vari6te B.
