PIERID.E. 51 



wardly bordered by a greyish band ; disco-cellular spot 

 almost always distinct ; inner-marginal band greyish, darker 

 at its extremity, where there is an upward projecting streak. 

 Hind-wing : slightly darker than in $ ; costal band indicated 

 by greyish ; band beyond middle rather darker ; connecting 

 streak but faintly indicated, except on costa.

A more thoroughly sylvan insect than A. Achine, being found more com- 

 monly in pathways and open spots m the woods than on their outskirts. 

 Its flight did not appear to me to be so rapid as Achine's, and it flew nearer 

 the ground, and settled more frequently. I only saw this species at Plet- 

 tenberg Bay, where it was very common in two kloof woods bordering the 

 valley of the little Bitouw river. It has, however, been taken at the 

 Knysna during this year (1860) ; which is an instance of how little de- 

 pendence can be placed on the experience of a single season, however 

 carefully and energetically one may work and observe.

$ . White ; with orange-red apical patch ; no trace of 

 longitudinal blackish bands. Fore-wing : apical red as in 

 $ of Omphale, a little more sharply indented by its outer 

 blackish border, its inner border slightly more obliterated a 

 little below costa ; base greyish ; no disco-cellular dot. Hind- 

 wing : base narrowly greyish ; a row of blackish spots along 

 hind-margin at extremities of nervules (obliterated alto- 

 gether in one specimen, below discoidal nervule). UNDER- 

 SIDE. Fore-wing: apical marking dull-orange inwardly, 

 pale-yellow outwardly ; a very small disco-cellular dot ; base 

 (in one specimen) tinged with pale-yellow. Hind-wing : 

 yellowish-white, or pale-yellowish, with a pinkish tinge ; 

 curved stripe beyond middle, and mark on costa, as in $ of 

 Omphale, but much paler in colour ; disco-cellular dot distinct, 

 orange, and black-dotted as in Omphale ; a few, very faint, 

 greyish irrorations along costa, from base. 



? . " Rather less than $ : bases of wings dusky ; red patch 

 paler and narrower ; inner-margin of fore-wings blackish, 

 ending in a spot which, as in the allied species, forms the 

 commencement of an arched, sinuate stripe crossing the hind- 

 wings ; hind-margin of the latter divided by rather large,
