of hindwiiifj twice as lonji' as D^, this equal in length to D' ; distal luarj^in of 

 forewing entire, apex produced, middle convex. 



Difters in colonr and shape from conjndotu as follows : Forewing with two 



brown basal dots and a minute brown stigma, discal lines closer together, dentate, the 

 teeth of the first directed basad, of the second directed distad, followed b}- a series of 

 vein-dots, the last enlarged ; outer margin less convex, apex more acute, inner 



angle mno.h less obtuse, about 1)0°. Hindwing more produced at anal angle, tlie 



dots before the augle more proximal. L'mli'rsidc : the two lines blackish brown, 



tlie external one accentuated by dots, the inner one of the hindwing more straight. 



Tenth abdominal segment as in con/tifloiii, the tergite narrower, less roniided 

 laterally, and the lobe of the sternite somewhat larger (PI. XXV. f 14). (.!lasi)er sole- 

 shaped ; patch of friction-scales as in cori/ndoni, but the scales more densely placed ; 

 liarpe (PI. XXXIII. f 2(1) with three processes : one {pv) as in cori/mloni, triangular, 

 appearing as a process of the clasper, the second and third prolonged, resemliliiig 

 somewhat the processes of fri.trcta, with which they are homologous, the lower one 

 straight, somewhat dilated at the obtuse end, the upper one curved, Iioth concave, 

 rough with minute tubercles or setae ; these processes correspond to the two lobes 

 of the sinuate upper process of corijndoni. Penis-funnel (p-f, PI. XXX. f. 35) 

 dorsally prolonged and divided into two long pointed blades ; penis-sheath with 

 long apical process which becomes gradually thinner towards end. 



¥ . Antenna slightly compressed, not distinctly grooved, the basal seriated 

 ciliae prolonged. More tawny than $. Distal margin of forewing more convex 

 in middle than in <?, the apex more jiroduced and the hinder angle more obtuse, 

 the lines much more indistinct both above and below, the veins of tlie hindwing 

 very slightly darker than the cellules between them ; anal dots more distal ; discal 

 line of hindwing below rather closer to cell. Eighth tergite mesially rounded, 

 projecting. Vaginal plate (PI. XVII. f. 14) not strongly chitinised, postvagiiial 

 part membranaceous, antevaginal jiart convex, wrinkled excej)ting middle, edge 

 broadly sinuate. 



Early stages unknown.

211. Polyptychus cousimilis spec. nov. 



(J. f'lose to eompar in colour; very difterent in the sexual armature. 



AVings, ahoi-e ; basal dot of forewing larger than in eompar, discal lines less 

 oblique behind, slightly curved basad behind 11', distal margin not convex beliiiul 



middle; hindwing paler in colour, more buff. Underside: lines more distinct, 



especially the tirst of the hindwing, D^ of the hindwing longer than D'. 



Tenth tergite (PI. XXV. f. 11) elongate-triangular, strongly narrowed to end, 

 pointed, mesially imi)ressed ; no sternite. Clasper (PI. XXXIII. f 22) witiiont 

 friction-patch; dorsal edge naked, incrassate, produced distad into a long denticulate- 

 truncate process {pdd) ; ventral part of apex of clasper {pdr) small, rounded, 

 concave ; harpe (h) incrassate, without processes ; a hairy, feebly chitinised cone (c) 

 between the incrassate ventral and dorsal marginsof the clasper. Penis-funnel (i'-k) 

 obliquely truncate, feebly sinuate ventrally, deeply sinuate dorsally, with long 

 bristles ; penis-sheath with the longitudinal groove oi eompar vestigial ; apex with 

 a mnltidentate belt (PI. XXX. f 34).
