postmedian band and a narrow wavy edged one before liindmargin, whicb, as well 

 the fringe, is pale. 



Underside of forcwings dark grey, of hindwings white ; fringe of both wings 

 white ; face and palpi above olive-brown, whitish below ; thorax and basal 

 segments of abdomen whitish ; rest of abdomen like hindwings. 



Expanse of wings : 28 mm. 



1 i,2 ? ?, from Cubal River, Angola, March LsiiO (Penricc). 



The antennae are lamellate, laterally flattened ; in the S closely serrate, with 

 clavatc teeth. The hindwings of 6 have a long oval hyaline space at base below 

 the median ; vein 1 apjiears to rise from its base and rnn.s into hiudmargin before 

 the anal angle. 



Subfamily HYDRIOBIENINAE. 



23. Ochjrria trientata sp. nov. 



Foreicings: whitish; this ground-colour, however, only showing in the band 

 beyond the central fascia, which is dark fuscous or blackish, occupying the middle 

 third of the wing ; its inner edge is regularly curved from one-third of costa to 

 two-fifths of inner margin, its outer forming a blunt double prominence in middle, 

 and a slighter one on vein ; the basal third is suftused either with dark fuscous, 

 reddish fuscous, or dull reddish ; the central fascia is edged outwardly first by a 

 fine white line, followed by a pale band with a dark thread through it, followed 

 in its turn on the costa by a dark blotch separated from the rufous fuscous 

 marginal area by an oblique apical streak ; the submarginal line indistinct, and 

 represented only by whitish spots at the ends of the teeth, which are sometimes 

 filled up with darker ; marginal dots in pairs at the vein ends ; fringe fuscons 

 varied with rufous, and chequered with darker beyond veins. 



Ilindwhujs : with the inner two-thirds grey, with three darker grey curved 

 lines ; the outer third reddish ; marginal spots distinct. 



Underside of both wings with basal two-thirds grey, outer third reddish ; the 

 forewings with cell-spot and three curved lines, the hindwings with ccll-sjiot and 

 outer dotted line only. Thorax and abdomen dark grey ; face and 2)rothorax 

 agreeing in colour with the basal jjatch. 



E.xpanse of wings : 2li mm. 



Nine examples, all cJ S, from Ran, Nandi Country, February 1890 (Dr. Ansorge). 



Easily distinguishable by the two colours of the underside ; the amount of red 

 showing through on the upperside varies much ; and iu one example the fuscous 

 tints of the basal two-thirds extend over the whole wing to the hiudmargin, 

 obscuring the markings. 



Subfamily PALYADINAE. 

 24. Melinoessa pauper sp. nov. 

 Forewingg : deeii yellow ochreous, covered throughout with dense and jiartially 

 confluent fulvous striae, the areas with fewest striae being those immediately beyond 

 the outer line ; a broad grey black-speckled costal streak ; first line nearly straight 

 at one-third ; second from two-thirds of costa, forms a more prominent beak 

 externally on vein 4 than is seen iu 21. sodaliata Wlk., its lower half reaching 

 inner margin at two-thirds, parallel to first line ; the submarginal line of silvery
