I30 SOUTH-AFRICAN BUTTERFLIES. 



antennas black, ringed beneath with white. Thorax black above, here 

 and there tinged with blue ; breast and legs white. Abdomen black 

 above, white beneath. 



$ Rather dull palc-hlue ; borders fuscous in fore-tving, fuscous-grcy 

 in hind-ioing. Hind-wing : a discal transverse interrupted fuscous 

 streak extending from second subcostal nervule to first median nervule ; 

 two black spots near anal angle enlarged and with large orange-fulvous 

 centres ; a similar brighter spot, inferiorly blue-scaled on anal angular 

 lobe. Under side. — Hind-iving : anal-angular spot more crimson than 

 fulvous. 



The above description of the ^ is adapted from Wallengren's, as I have 

 not seen an example of that sex.^ The 5 agrees with it in all respects except 

 those just noted. 



In tint of blue, /. Trimeni ^ appears to resemble /. Sielus, to which species, 

 as regards form, Wallengren compares it. In its large size, however, and 

 very feebly-marked under side, Trimeni is much nearer to Silas, Westw. ; 

 but the (J appears to want the crimson upper-side spots near the anal angle 

 of the hind-wing, while the $ 's orange spots are very much less developed ; 

 and on the under side the red transverse discal streak is wanting in both 

 wings. 



This appears to be a rare species. The single specimen received by 

 Wallengren is noted as having been taken in December on the crest of a 

 mountain on Schoman's Farm near the Vaal River. The $ here described 

 and figured was sent to me in 1873 by Mr. H. Barber, who took it in some 

 part of the Transvaal, but made no note of the particulai' locality.

$ Soft pede blue ; apical hcdf of fore-wing hlach ; circular costal 

 patch on hind-wing large, conspicuous, glistening-whitish, broadly 

 ringed with blackish. Fore-unng : costa grey, edged with pale-reddish 

 near base, abruptly widening and deepening into apical black before 

 extremity of discoidal cell ; blue forming an imperfect semicircle, having 

 for its base the inner margin of wing, but not reaching anal angle, to 

 which the apical black (covering the entire hind-margin) narrowly 

 extends. Hind-wing : hind-margin edged with a .black line ; three 

 tails precisely as in Silas, but less twisted ; i"nner-margiual groove 

 dark-grey, clothed and fringed with whitish hairs ; lobe of anal angle 



^ Though "9 " is printed in Wallengren's descriptimi, it is certain, from the mention of 

 the circular costal spot of the hind- wings, that the 6 was intended.
