a row of dark marginal spots betwoen veins ; fringe concolorons, with minnte dots 

 beyond veins ; cell-spot variable, sometimes hardly marked, sometimes distinct, 

 blackish. 



Hindwings : like forewings, but the cell-spot oval, silvery white, followed by a 

 nearly straight smoky black median shade. 



Underside rather clearer ; the markings indistinct 



Head, thorax, and abdomen all concolorons. 



Expanse of wings : 34 mm. 



Five ? ? from Warri, April 1897 (Dr. Koth). 



Smaller than Pisoraca leonaria Wlk., more uniformly coloured ; the anal angle 

 of hindwings more prominent ; the hiudmargin less strongly creuulate ; the smoky 

 median shade is often obsolete : the white discal spot of hindwings sometimes ringed 

 with black. 



Pleionocentra gen. nov. 



Like Craspedia, but the hiudtibiae of the S not reduced, and with terminal 

 spurs, those of the ? with four spurs; antennae of <? with rather long fine ciliatious: 

 wings short and broad ; vein 3 of both wings and 7 of hindwings from before angle 

 of cell. 



Type : rbnonocentra minorata Boisd. 



The two existing genera of Sterrhinae in which the hiudtibiae of the S (tre 

 armed with two, and those of the ? with four, spurs are Cinglis Guen. and Lycanges 

 Butler : but Cinglis has the S antennae strongly fasciculated, while Lycauges is 

 characterised by the very long narrow wings, with oblique markings. 



53. Ptochophyle hilaris sp. nov. 



Forewings : yellow, densely irrorated witli purjilish red, especially along costa ; 

 the irrorated parts forming a basal patch and central, outer, and marginal fasciae 

 separated by narrower yellow fasciae: an irregular row of red marginal spots: cell-spot 

 deep red ; fringe yellow. 



Hindwings: similar, but less thickly irrorated with red, the bands narrower ; 

 costa yellow ; two red spots on discocellular, one at each end. 



Underside duller ; head and thorax purple-red ; abdomen yellow. 



Expanse of wings : 22 mm. 



One ? from Warri, Niger Coast Protectorate, September 1897 (Dr. Both). 



54. Ptychopoda aequisinuata sp. nov. 



Forewings : silky ochreous, the costa reddish-tinged : the lines fuscous, starting 

 from dark marks on costa, first from one-tliird, second just beyond one-half, tliird 

 from two-thirds, of costa to one-third, one-half, and two-thirds of inner margin, all 

 sinuate outwards above to the snbmedian fold, then oblique; submarginal line finely 

 waved, between darker ochreous shades, which on inner margin and at anal angle 

 form fuscous blotches ; marginal line blackish, interrupted by the pale veins, and 

 altogether indistinct below middle ; fringe strongly rnfous-tinged, with black dots 

 along base beyond the ends of veins ; a large black cell-spot. 



Hindwings : like forewings, but without first line ; the median line antemedian, 

 and the submarginal shades fuscous at apex. 



Underside paler, with all the markings clear ; base of forewings fuscous. Face 

 and palpi black-brown ; vertex, thorax, and abdomen concolorous.
