( 489 ; 



[iilikc tlie tyjie species the himlinargin of forcwings is not angled at vein 5, 

 Imt i>i(Mluce(l into a large curved iironiiiience between veins 2 and .J. above which 

 it is deeply excised, leaving the a[ie.\ stronglv falcate; the angle at \eiii 6 of the 

 hindwings is much blunter. 



Family THYRIDIDAE. 

 4. Banisia pusillata sp. nov. 



Foretvings : pale ochreous, striated and partially reticulated with rufous- 

 ochraceous, the basal half slightly sutfused with rufous ; no distinct lines ; liasal line 

 of fringe slightly darker, especially beyond cell ; fringe pale ochreous. 



Himhi-liif/s : sinular. 



Underside with all the striae plainer and nii.xed in places with fuscous scales. 

 Head, thora.x, and abdomen concolorous. 



Expanse of wings : 17 mm. 



One ? from Agberi, Nigei-, July 1901 (Dr. Ansorge). 



Smaller than, and of quite a different colour from, B. curvilineii \N'arr.. the 

 markings less expressed. 



Fa.mily EPII'LEMIDA E. 



5. Dirades angulifera sp. nov. 



c?. Forcwings: dingy olive grey, suffused and .slightly dusted with darker; 

 markings all very much obscured; a darker central fascia, of which the inner edge 

 i.s much inbent in cell and marked with a dark blotch ; the outer edge angled at 

 vein 6, inbent beyond cell, then out curved, and marked with black on inner margin; 

 this fascia beyond the cell and on submedian fold is followed by pale ochreous 

 blotches; its middle is connected with the hindmargin by a dull cloud, through 

 which an interrupted submarginal band i)asses ; while nearer still to the margin and 

 jiarallel to it is a dark line, beyond which the apex is dull chestnut-brown, and the 

 anal angle blackish; fringe dark fuscous. 



Hindwings: with the central fascia curved, indistinctly edged, with a blunt 

 angle below median, followed by a paler hand, beyond which the margin towards 

 apex is deep brown, becoming paler and more ochreous towards anal angle ; a black 

 spot below lower tooth ; fringe brown above middle, ochreous below. 



In the ? the outer edge of fascia of bindwing is very strongly angled on vein 2, 

 edged thickly with deep velvety black, and followed first liy a pale and then a dark 

 line, the inner edge also lined with lilack. 



Underside dull einerous olive in forewings of c?, the hindwings slightly paler;, 

 in the ? the underside is paler, and more freckled with dark, but none of the ? ? 

 are in good condition, and when fresh may jiossibly resemble the iS more closely. 

 Head, thorax, and abdomen concolorous with wings; vertex white; face and palpi 

 black. 



Expanse of wings : S 2r) mm. ; ? 2(5 — 30 mm. 



One i perfect, one ? worn, dated .lanuary 1901 ; three ? ? much worn, dated 

 March 1901 (Doherty); all from the Escarpment, British East Africa.* In the i the 

 teeth at veins 4 and 7 are more conspicuous than in the ? ¥ , and there is also a 

 smaller tooth at vein C. The strong black angulated line in the hindwings of the ? 

 and the brown apices will readily distinguish the insect. 



* This is the Kikuyu Escarpment, east of the Ravine.
