XOVITATES ZOOLOGICAE XXII. lUlS 



Streak near base on subniedian fold ; inner line just liefore middle black, slightly 

 curved, and indented on each fold, preceded by two curved brown shades, the 

 inner strongly outcurved at middle ; median fascia extremely narrow, towards 

 inner margin whitish ; the outer line blackish, slender, crennlate, and slightly 

 jirojecting on vein 4, followed by two thick brown shades with deeper centres, 

 and then by a black Innulate-dentate line, angled above vein 5; subterminal line 

 jiale fawn between darker shades, met at vein 6 by a thick somewhat inter- 

 rupted streak from apes ; a row of fine black lunules before termen ; orbicular 

 and reuiform stigmata represented by linear black marks of raised scales, with 

 some paler scales on their inner edge, lying on the inner and outer lines respec- 

 tively ; fringe pale fawn, rayed with darker, with a dark broad middle line and 

 bright pale basal line. 



Hindwing : brownish fuscous ; the fringe pale, with thick dark middle line. 



Underside dull cinereous ; each wing with three dark curved lines in outer 

 half, the middle one dentate on the veins ; costa of forewing fawn-colonr. 



Head, thorax, and abdomen fawn-colonr; the tegulae with two ill-defined lines 

 and their tips blackish ; tarsi with the joints blackish ; foretibiae in front with 

 three black dots. 



Expanse of wings : 34 mm. 



1 S from Sikkim, August 1889 (Col. Pilcher). 



10. Polyploca nigrifasciata spec. nov. 



Foreioing : whitish sufl'used with brown and fuscous, the whiter scaling only 

 showing in the terminal third of wing; a short white streak at base below 

 median vein, and often the base of costa white ; median area brown, traversed 

 by four or five irregularly crennlate black lines ; the inner most escurved above 

 middle and indented below on submedian fold, partially edged with whitish 

 scales ; the outer followed by a whitish band with a black crennlate line at 

 middle ; a dark fuscous band before subterminal line, mixed with whitish grey 

 scales at costa and below middle ; a white costal patch at apex above the black 

 oblique apical streak ; terminal line black, lunulate ; fringe pale grey mottled with 

 black beyond veins ; reniform stigma a strong black linear mark of raised scales ; 

 the whitish areas are generally more developed in the 5, and the black fascia and 

 outer band stronger ; the white basal scaling is also edged with black. 



In another form, ab. semifascia ab. nov., the whole ground colour is dull chalky 

 white, with the dark median fascia cut off at median vein, its edges only indicated 

 on inner margin ; some slight dark shading at base round the white scaling ; the 

 black apical streak present, and a grey spot on inner margin before subterminal 

 line; the grey markings rather better defined in the S. A third form, ab. 

 nigrilineata ab. nov., mimics the form of orbicularis Moore called bifasciata Hmps., 

 only the black edgings of the median fascia being shown, the inner of two black 

 lines, the outer of one only except at costa; in both of these aberrations the 

 orbicular stigma, as well as the reniform, is represented by a linear black mark. 



Hindwing : fuscous, the fringe paler. 



Underside dark fuscous, paler in the ? ; the costa of the forewing white with 

 black strigae. 



Head, thorax, and abdomen mixed black and white, the white predominating 

 in the pale aberrations ; tarsi thickly spotted with black. 



Expanse of wings : cj, 3G mm. ; ? , 38 mm.
