ill a biangulated series from costa to first median interspace, and a brown spot at the 

 end of the cell ; secondaries entirely bright gravel-ochre, a spot at the end of the 

 cell, the tapering costal dash of the upper surface and five inconspicuous spots iu 

 continuation of the latter coffee-brown ; pectus clothed with salmon-pink hair. 



Expanse of wings, 56 mm. 

 Graham's Town. 



In the Hewitson collection there is a pair of this species, mixed up with three or 

 four other species, as T. JEris : the male diifers from that sex of T. Eris, in having a 

 conspicuous black spot at end of cell, the apical patch elongated transversely instead 

 of along the costa, its outer portion cupreous on the border, grey-brown within the 

 border, the spots upon it broad, oval and bright ochreous ; the black externo-discal 

 area inclosing two white unequal spots in continuation of the sub-apical series, and 

 below tlicse spots with a dentate-sinuate white border ; the black costal band of 

 secondaries is slightly differently shaped from that of T. Eris, and (as in the female) 

 there are no marginal spots to these wings ; on the under surface the primaries have 

 a black spot at end of cell as above, also two small spots just beyond the centre of 

 the median interspaces ; the costal margin and apical area and the entire surface of 

 secondaries deep rosy flesh-coloured ; the secondaries with a tapering brown dash 

 from costal margin, and a small brown spot at end of cell ; pectus with pink hairs. 



Expanse of wings, 53 mm. 



Hewitson has, as usual, no definite localities on his specimens, the 

 male being labelled simply " Cape," and the female " S. Af." 



The following, which is the largest species of the group, I 

 describe as — 



Teracolus opalesce>'S, sp. n. 



$ . Nearest to T. Maimuna from Angola, considerably larger, the wings white 

 with rosy opaline shot, much more pronounced, especially on the primaries, than in 

 any other known species ; primaries above with the costal border narrowly irrorated 

 with brown scales, giving it a greyish tint ; external and internal borders very broad, 

 more so than in T. Maimuna, the three sub-apical yellow spots only represented by 

 a few scattered yellow scales, but the white patch at external angle wider than usual ; 

 secondaries with the marginal spots unusually large ; the spots across the disc forming 

 a regular arch instead of an angle followed by an arch as in T. Maimuna, the first 

 spot only large, the others quite small ; primaries below white, the apical area tinted 

 with clear sulphur-yellow, and not crossed by rust-red spots as in T. Maimuna ; three 

 spots only on the disc, two of which (on the median interspaces) are large ; a trans- 

 verse black stigma at the end of the cell ; sccondai'ies clear sulphur-yellow ; a small 

 red-brown spot at the end of the cell, and eight in an arched series from costa to 

 interno-median fold across the disc ; costal margin gamboge-yellow ; body below 

 white. Expanse of wings, 62 mm. 



Delagoa Bay. 



The female of T. Maimuna measures 57 mm. in expanse of wings ; 

 it is always more or less, and sometimes wholly bright yellow on both 

 surfaces ; when white above, it has three conspicuous yellow sub-apical 

 spots, and the anterior half of the wing on the under surface washed
