3(52 NOVITATES ZoOLOGICAE XXII. IP15. 



gronnd-colonr both above and beucath being strongly snffnsed almost thronghont 

 with deep fiiscons, on the forewing above with a few spots at costa, and an ill-defined 

 patch in distal area from the radials to near tornns, on the hindwing above 

 with the beginning at inuer-margin of a narrow band between median and post- 

 median lines remaining less suffused. 



Forewiiig marked nearly as in aborta, the lines deeper black, both thickened at 

 costa; postmedian rather less oblique, its acnte angle in front of R' not approaching 

 so near the termen; median shade vague, but connected with postmedian line by 



some black shading in middle of wing ; cell-spot perhaps less enlarged. Ilind- 



iciiiq with median shade and postmedian line almost as in aborta but blacker, 

 rather near together. — Underside with postmedian line rather sharper than in 

 aborta. 



Bitye, Ja River, Cameroons, 200U ft., September— November 1911. Type in 

 coll. Rothschild. 



The venation, if constant, affords a further distinction : in //. aborta SC arises 

 from the cell, well away from SC- ; in dnophcra it is shortly stalked with SC'- ; in 

 both it anastomoses with 0. They agree in having the forewing more shortened 

 and ronnded than in typical Hemerophila ; H. serrataria Walk. {List Lep. Ins. 

 xxi. 412 ; = denticulata Warr., Bat. Zool. xi. 473 = curta Warr., op. cit. xvi. 119), 

 from Natal, has a rather similarly shaped i, but has SC'"- coincident, generally 

 well separated from C. 



100. Hemerophila rotifera sp. nov. 



?, 35 mm. Head grey-brown with some darker irroration. Palpus rather 

 short. Antenna with single bristles almost as long as diameter of shaft. Thorax 

 and abdomen grey mixed with brown. 



Forewing rather broad, apex almost rectangular, termen crenulate, obliquely 

 curved in posterior part ; SC anastomisiug slightly with U, S('^ free ; proximal 

 and distal areas brown, slightly mixed with grey and clouded with deep fuscous ; 

 central area grey, with slight and sparse brown irroration (stronger costally) ; lines 

 fine, brown ; antemedian from about two-fifths costa to one-fourth hindmargin, 

 sinuous, strongly oblique inwards in posterior half; postmedian angled inwards 

 subcostally, acutely bent outwards before R' (the tip of the projection obsole.scent), 

 oblique inwards and somewhat sinuous to three-fifths hindmargin ; a round brown 

 cell-spot fully 1 mm. in diameter ; a very ill-defined median shade traversing the 

 grey area between cell-spot and postmedian, less angled outwards than the latter ; 

 dark clouding in terminal area weaker distally than proximally, but without A\a.v\) 



demarcation ; terminal line interrupted, expanded into spots between the veins. 



Ilindwing with termen strongly crenulate ; mostly brown, somewhat greyer near 

 base, a grey, slightly browu-irrorated patch distally to subterminal line from 

 tornns to middle ; discal spot small, not sharp ; a feeble, nearly straight, rather 

 thick postmedian line from three-fifths hindmargin, bent near costa but becoming 

 almost obsolete ; subterminal pale line somewhat crenulate, almost obsolete, carved 

 from tornns to radial fold, where it again ajiproaches termen ; a narrow dark band 

 jiroximally to the subterminal, obsolete towards costa ; interrupted terminal lino 

 and spots strong anteriorly, weak posteriorly. 



Both wings beneath duller and more uniform, with fuscous irroration and 

 vague fuscous subterminal baud ; forewing with rather large, hindwing with 

 slightly smaller cell-spot.
