LYCzENID^E. 127 



only species as yet met with in the western districts of the Cape Colony 

 is /. Bowkeri, of which I captured several specimens at Robertson in 

 1875 and 1876; but in the eastern districts /. Silas, Sidus, Mimosa;, 

 and Aphnccoidcs occur, — the last-named being apparently of extreme 

 rarity, /. Pallene is a tropical species, and has hitherto not been found 

 in South Africa proper, except in Swaziland. 



Of the thirty- seven species recorded, no fewer than eighteen are 

 African ; and of the rest, one is Arabian, ten are Indian, seven from the 

 Malayan Archipelago, and one from some unregistered locality.

$ Metallic purc-hlue, vjithout any jmrj^lish tinge. Fore-iving : blue 

 forming a large semicircle ; a moderately-wide black border on costa 

 becomes very broad at apex, extending thence rather broadly to anal 

 angle ; inner-marginal tuft of hairs ochrey-yellow. Hind-wing : a black 

 costal and hind-marginal border, rather variable in width, but becom- 

 ing very narrow towards anal angle ; a more or less complete black 

 streak parallel to it, between discoidal nervule and submedian nervure, 

 interiorly edges two crimson-red spots between submedian and second 

 median nervule ; on anal-angular lobe, a crimson, blue-dusted spot ; 

 inner margin rather widely dark-grey ; tails black, white-tipped, that 

 on submedian white-edged ; shining costal circular space black, filling 

 nearly whole of cell. Cilia of fore-wing grey ; of hind-icing white. 

 Under side. — Glistening white ; a common, transverse, didl, crimson-red 

 line leyond middle. Fore-wing : line commencing near costa, inter- 

 rupted on each nervule, not reaching inner margin, often indistinctly 

 marked. Hind-wing : streak well marked, straight from costa to second 

 median nervule, where it bends outwardly, forming a spot (correspond- 

 ing in position with the superior of the two spots on upper side), 

 beyond which it is black, interrupted, and inclining inwards to inner 

 margin ; immediately before this part of line, a similar interrupted 

 black one, not reaching beyond submedian ; spot on lobe conspicuous, 

 including a black spot ; an indistinct greyish clouding between line 

 and hind-margin, which is black-edged towards anal angle. 



$ Blue 2mle, faint, inclining to violet, not metallic, occupying a 

 smaller space, so that the dark margins (which are dull-blackish) are 

 broader, especially in hind-wing. Fore-wing : blue much paler on 

 median nervules, occasionally almost white. Hind-wing : black streak 



^ In this figure the dentation at the extremity of the second median nervule of the hind- 

 wings has been erroneously lengthened into a linear tail.
