1 c?. A long series in coll. \V. Schaus. 



2. Polyptychus baxteri spec. uov. 



c??. Body and wings viuaceons; nppcrside of head, thorax, and of forewing 

 shaded with grey. Second segment of palpns large, joint between first and second 

 open. Tibiae spinose, upperside of mid- and hindtibiae white. A difi'use central 

 line over thorax and occiput blackish chestnut. Forewing with even distal margin, 

 the apex being pointed, bnt not produced ; two oblique blackish chestnut lines from 

 costal margin, the first at basal fourth, extending to hindmargin near angle, the 

 second in middle, vanishing on disc in a cloud of brown scaling ; a short third line 



at costal margin halfway between the second and the tip of the wing. Apex of 



liiudwing rounded, distal margin even, except that the anal angle is iiroduced, 

 this angle brown. 



Underside : outer two-fifths of forewing washed with brown, within this brown 



area traces of one or two lines. Hindwing with two thin lines across ilisc, the 



outer one being dentate.

3. Polyptychus retusus spec. nov. 



S. Nearest to P. nigrijAaga R. & J., Xov. Zool. ix. Suppl. p. 2r)0. n. 222. 

 t. 5. f. 4. $ (1903) (Kamerun). Second segment of palpus apically wider, spurs 

 of hindtibia shorter, the longer one of the apical pair only a little longer than 

 the tibia is broad. 



Forewing narrower, the distal margin distinctly concave, tlie apex being 



produced. Hindwing blackish, anal angle j)roduced, the black anal dot nearer 



the distal edge than in nigriplaga ; the fringe without distinct dots ; an elongate 

 patch before abdominal margin deeper black than in nigriplaga. 



Underside blackish brown, distal marginal area of forewing grey, markings as 

 in nigriplaga, bnt the submarginal dots and on hindwing also the submarginal 

 anal line nearer the edge. 



Genitalia similar to those of nigriplaga, bnt the clasper ventrally widened from 

 base to two-thirds, then abruptly narrowed, remaining however wider at the apex 

 than in nif/riplaqu ; just beyond the widened ventral portion a thoni-like tooth 

 pointing obli<piely ventrad, being much more proximal than in nigriplaga ; process 

 of penis-sheath as long as in nigriplaga, but broader, bearing a small tooth at 

 the dilated tip.
