^ Grecnish-ichite, luith a hright 'pcarhj lustre, most hrilliant near 

 bases of iving. Fore-iuing : 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-ioing : a series of 

 seven minnte black dots (rarely absent) along hind-margin, at extre- 

 mities of nervules ; base more or less blackish. 



Under side. — Varialle. Fore-wing: a very small black dot at 

 extremity of discoidal cell ; costa narrowly, apex hroaclly, tinged with 

 very pale dull-yelloivisli, sprinhlcd more or less thichly with dark-grey 

 dots. Eind-iving : entirely of the same pcde-yellowish, thieliy sininkled 

 with grey atoms ; costa at base tinged with pialc hright 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-ioing. (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.) 



$ PMthcr more yclloivish than $, hut vjith the same pearly lustre, 

 which is indeed considerahly more extended in hasal area of fore-wing. 

 Fore-iving : 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 ; spiots on hind-margin very much larger than in $, 

 contiguous, somewhat rhomboidal inform, {in some instances almost form- 

 ing a margined stripe), the last spot on submedian nervure. Hind- 

 wing : dots on hind-margin larger than in ^, but not one-fourth the 

 size of those in fore-wiug; 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 

 deusely irrorated constitute his Varii'te B.
