PIERID.E. 55 



Since the above was written I have discovered the female of A. Evanthe 

 in the collection of the South African Museum. So different is its appear- 

 ance on the upper-side to the male insect, and so very delicate its structure, 

 that I had doubtingly referred it to the Genus Pontia. But more care- 

 fully examining it on one occasion, more recently, I was struck with the 

 resemblance of the under-side to that of the male of Evanthe already de- 

 scribed. On comparison, I no longer doubted its right to be considered as 

 the same species ; and I may add that my friend Mr. E. Layard agrees 

 with me in thinking it A. Evanthe. Mr. Layard took the two examples in 

 the Museum on the coast of Madagascar during the same voyage that the 

 $ specimens were captured.

White ; with blackish apical border. Fore-wing : no trace 

 of orange at apex, or of the blackish stripe that borders the 

 orange internally in the $ , but [a simple, rather broad, 

 blackish band, sinuate internally, commencing on costa 

 further beyond middle than in $ , and ending on hind-margin 

 a little below second median nervule ; greyish at base slightly 

 darker ; disco-cellular spot larger, black and conspicuous. 

 Hind-wing : base greyish ; minute black dots clouded with a 

 minute halo, as it were, of blackish scales, on hind-margin, 

 at extremities of nervules. UNDER-SIDE. Quite similar to 

 $ , excepting for the narrower apical marking, untinged 

 with the faint orange hue, and the larger disco-cellular spots. 

 Hind-wing : a little yellower in tint than in $ , and perhaps 

 a little more closely irrorated with grey.

 $. Bright pale sulphur-yellow ; with orange apical patch. 

 Fore-wing : orange at apex more inclining to yellow than in 

 any of the species already described, occupying nearly half 

 the area of forewing, bordered externally by a black stripe, 

 widest at apex, slightly indenting the orange, narrowing to 

 lower extremity of orange marking, beneath which (im- 

 mediately above anal angle) it suddenly widens, forming a 

 blackish spot and internally by an ill-defined, faint-blackish 

 stripe, variable in width, and sometimes all but obsolete ; base 

 blackish ; costa edged with black ; disco-cellular spot wanting. 

 Hind-wing : a few indistinct faint-blackish spots on hind- 

 margin at extremities of nervules, in some specimens scarcely
