75. Ectropis zebrina sp. nov. 



Foreiviwjs: pale grey, thickly speckled with fuscous; crossed by four blackish 

 waved lines, rising from dark costal spots; first from one-fourth of costa to one-third 

 of inner margin, curved ; second from two-fifths of costa to before middle of inner 

 margin, approaching basal line there, outcurved above and below median; third 

 from two-thirds of costa to two-thirds of inner margin, strongly outcurved above, 

 approaching and nearly touching second line on submedian fold; fourth at five- 

 sixths, curved parallel to hindrnargin ; traces of a fifth dark line close before mai-giii. 



Hindwinr/s : with four lines; the cell-spot in both wings touching the second 

 line. 



Underside dull U'llow; forewings crossed liy (wo thick black fasciae; first 

 straight, from two-fifths of costa to two-thirds of inner margin; second from two- 

 tliiids of costa, curved, running into a broad black marginal border, which is 

 interrupted at the middle of wing; apex and lower half of hindmargin narrowly 

 pale; hindwings with the marginal black border slill wider, and one band only, 

 curved from one-third of costa to two-thirds of inner margin; the whole hindmargin 

 narrowly pale. Head, thorax, and abdomen grey ; face and palpi dark fuscous. 



Expanse of wings : 30 mm. 



Two S tS from Yakusu, Upper Congo, July 1900 (K. .Smith).

Foreivings : pale ochreous, dusted with black scales, and varied with dilTerent 

 tints of brownish grey and pinkish gi-ey ; costa with vertical striae of olive-giey ; 

 basal line blackish, thickened at the costa, from one-third of costa to one-sixth of 

 inner margin, acutely but shortly angled on the subcostal vein, bluntly angled on 

 median, preceded by a similar but less prominent brownish line, the intervening 

 .sjiace often filled up with dark below the cell-fold ; outer line from three-fourths 

 of costa, inangled on subcostal vein, acutely angled outwards just above vein 6, 

 thence oblique parallel to hindmargin, hinulate dentate, to middle of inner margin, 

 followed by a thick brown line, and preceded closely by a fine median line, angled 

 like itself on vein C : cell-spot black, small, sometimes surrounded by a dark cloud, 

 and connected with a wedge-shaped brown blotch lying inside the outer line beyond 

 the cell; submarginal line with acute teeth, where visible, but much interrupted; 

 marginal area interrupted by a brown shade fiom above vein 4 to vein 7, containing 

 three black streaks between the veins; anal area with brownish clouds; marginal 

 festoon black ; fringe brown, darker and mottled from \ein 4 to 7. 



Hindwings: with first line close to base, the outer at two-thirds, followed by 

 a brown shade and preceded, as in forewings, by the median line, the whole space 

 between median line and outer area being generallv suffused with brown and forming 

 a fascia; submarginal line incurved, indistinct, the marginal area lieyond il from 

 anal angle to vein 4 pale cream-colour with brownish suft'usion and striae; marginal 

 line and fringe as on forewings. 



Underside pale ochreous, mottled with fuscous-grey; cell-siiots large and black, 

 formed of rough, semi-erect scales ; a broad dull blackish marginal band, not 

 touching costa, and leaving a pale blotch on margin between veins 3 and 4, which 

 is extended to anal angle on hindwings, and precedeil by the dark outer line.
