336 Mr. Roland Trimen on 



with silvery on anal angular lobe. Underside. — As in 

 $ , but the bars and spots proportionally narrower, leaving 

 more of the silvery-white ground colour unoccupied. 

 (Described from ten S and one ? specimens.) 

 This AphncBus is a^ near ally of A. Phanes, mihi 

 {Tr. Ent. Soc. 1873, p. Ill, pi. i., figs. 4, 5), resembling 

 the latter particularly in the silvery-white ground colour 

 of the underside, and the great development of the yelloAv- 

 ochreous bands on the upperside of the ? . The chief 

 difference of importance is presented by the underside of 

 the hindwing, in which, instead of being rather even and 

 almost parallel, the oblique bars are irregular and almost 

 sub-macular, and the outer one is so strongly angulated as 

 to be confluent with the inner one near the end of the dis- 

 coidal cell. This an-angement breaks the silvery ground 

 colour beyond the middle into three irregular marldngs, 

 and gives the underside an appearance quite different from 

 that of other Aphncei. Other distinctions from A. Phanes 

 are (in the $) the very undeveloped state of the ochreous 

 forewing upperside markings, which in one example are 

 very small and dull, and in another all but obsolete ; and 

 (in the ? ) the different arrangement of the hindwing 

 upperside markings, Avhich in both species follow, or 

 correspond with the silvery-white portions of the under- 

 side. In both sexes, tlie very dark colouring of the spots 

 and bars of the underside is a marked distinguishing 

 feature. 



I first met with this species under a thorn-tree (known 

 as the " One Tree" in a wide expanse of country) a few 

 miles from Annenous, on the line of railway laid down by 

 the Cape Copper Mining Company, and afterwards on 

 the road between Elboogfontein and Kockfontein ; near 

 the Komaggas Mission Station; and at Oograbies ; but it 

 was numerous at the latter place only. It has the short 

 active flight of its congeners, but is less wary when 

 settled. ^ It usually rests on the bare twigs of some low 

 shrub, with its head downward, and when disturbed will 

 sometimes return to the same perch. The $ has a very 

 dark, almost black appearance on the wing, but the only 

 ?_ I met with had in flight more the look of ^. caffer, 

 mihi.
