LYC/ENID.E. 131 



marked with a pale crimson-red spot, outwardly black dotted, and 

 marked with a few bluish scales ; a small, indistinct, similar spot 

 immediately above it. Cilia greyish in fore-wing, white in hind-wing 

 (tinged with yellow near anal angle). Under side. — White, tinged 

 with greyish ; one transverse ferruginous-red streak in fore-wing, two 

 in hind-wing ; costa and hind-margin of fore-wing and hind-margin of 

 hind-wing with an orange edging. Fore-ioing : ferruginous-red streak 

 rather broad, straight from costa beyond cell, in direction of anal angle 

 to second median nervule, where it abruptly terminates ; a semicircular 

 patch of grey on inner margin near base, and lying over it a curious 

 row of long black hairs springing from edge of inner margin ; near 

 anal angle, above submedian nervure, an elongate blackish mark. 

 Hind-iving : first red streak as in fore-wing, from costal nervure (before 

 middle) as far as first median nervule, where it narrows, and is thence 

 a biangulated thin Uack streak to inner margin a little beyond middle ; 

 outer red streak not far from and almost parallel to hind-margin, narrow- 

 ing and becoming almost obsolete after passing discoidal nervure ; space 

 between streak and hind-margin greyish, enclosing an additional red 

 spot between second and first median nervules similar to that at anal 

 angle, which is larger than on upper side, merged with the smaller red 

 spot, and outwardly edged with a bluish line ; from discoidal nervure 

 the hind-marginal edging is black. 



$ Violaceous-ivhitish, suffused ivith hi ice from bases. Fore-iving : 

 border narrower and dusky-blackish. Hind-umig : costa with a dusky 

 border, widest at apex ; from it run two diminishing dusky streaks 

 along hind-margin, the outer as far as second median nervule, the inner 

 indistinctly to inner margin ; spot on anal angle, with that above it 

 (which is large) centred with white ; a third, conspicuous, subquadrate, 

 orange, black-dotted spot between second and third median nervule. 

 Under side. — Quite like that of ^, save for the absence of any grey 

 patch on inner margin of fore-wing ; and the spots on hind-wing being 

 less conspicuous. (Described from single specimen.) 



The $ is readily distinguished from ^ /. Silas, Westw., by its 

 smaller size, less glittering blue surface, strongly and doubly streaked 

 under surface, with its orange edging, and more conspicuous circular 

 patch on up]3er side of hind-wing. The front of the head and bases of 

 pterygodes, which are both black (the former being white striped) in 

 Silas, are ferruginous-red in Sidus. The fringe of hairs on inner 

 margin of fore-wing, which is yellow in Sileis, is black in the latter 

 species. The $ is very different in the two species. 



This very handsome lolaus was discovei'ed by Colonel Bowker in Ivaffraria 

 in the year 1862, and in the following year Mr. H. J. Atherstone met with 

 it on the coast of the Bathurst District in Cape Colony. The former noted 

 it as rare and local, occurring from December to April,^ and took most of his 

 specimens on a Sneezewood tree [Pteroxylon utile) at the edge of a forest. I 



^ He subsequently wrote that he had observed it throughout the year.
