PIERID.E. 79 



at apex, and continued more narrowly to anal angle, where 

 it again slightly widens, its inner edge forming very slight 

 denticulations on the nervules. Hind-wing : sub-angulated, 

 there being a slight projection of outline on second median 

 nervule ; yellow much paler on inner-margin ; a narrow, 

 black, hind-marginal edging, considerably dentate on its 

 inner edge, diminishing to a point at extremity of third me- 

 dian nervule or submedian nervure. UNDER-SIDE. Sulphur- 

 yellow. Fore-wing : tinged with pale-ferruginous at apex, 

 which colour diminishes along hind-margin to a point at anal 

 angle ; a streak of darker-ferruginous, slightly waved, be- 

 ginning near costa just before apex, touches first median 

 nervule ; a blackish, yellow-centred mark at extremity of 

 discoidal cell ; and a small, very faint, blackish dot within 

 cell, not far from base ; yellow much paler on inner margin. 

 Hind-wing : not irrorated ; marked as in T. Rahel, but with 

 ferruginous instead of blackish ; a very narrow, pale-ferru- 

 ginous line along hind-margin ; a minute black dot at ex- 

 tremity of each nervule.

Pale sulphur-yellow ; irrorated with blackish. Fore-wing : 

 irrorations darkest and thickest near base and along costa ; 

 bordering blackish, much broader than in $ at apex and 

 along hind-margin, not so sharply defined on its inner edge. 

 Hind-wing : less irrorated than fore-wing, principally so at 

 base and central portion ; inner-marginal portion very pale, 

 not irrorated ; hind-marginal band blackish, ill-defined, 

 forming dentations on nervules (in one specimen being little 

 more than nervular markings, just touching at their extreme 

 points), not extending beyond third median nervule ; pro- 

 jection of outline at extremity of second median nervule 

 rounder than in , but quite distinct. UNDER-SIDE. Much 

 paler than in $ ; the markings similar, but indistinct, and 

 more greyish. Fore-wing : minute dots at extremities of 

 nervules distinct ; in one specimen the ferruginous hind- 

 marginal edging is entirely wanting. 



The sub-angulated outline of the hind-wings of two female specimens 

 of Terias from Natal first induced me to separate them from other spe- 

 cimens which I have mentioned above as supposed females of T. pulchella, 

 Boisd. The male of T. Desjardinsii possesses this peculiarity, and noticing 

 the markings of the underside in these female specimens to be very similar 

 to those of the male of the last-named species, I give a description of them, 

 as a suggestion to those who may have an opportunity of investigating the 

 matter. Dr. Boisduval states that he was not acquainted with the $ of 

 this insect.
