middle and at inner margin; orbicular stigma very small, round, with fuscous centre and whitish an¬ 
nulus defined by redbrown; reniform ochreous defined by dark brown, with slight brown lunule in centre 
and fuscous spot in lower part, narrow, with the upper and lower extremities strongly produced; minute 
dark terminal lunules; fringe mottled, ochreous and brown; hindwing reddish brown, with the fringe 
ochreous; $ without the leaden grey suffusion of fore wing; the area between the two lines dark brown 
to submedian fold, in which there is a black streak. Port Blair, Andaman Islands. 
9. Genus: Stenopterygia Hmps. 
Differs from Dipterygia Stph. chiefly in the longer palpi, which reach to vertex of head, the 
third segment longer and somewhat porrect; insects of somewhat smaller size and narrower forewings; 
more uniformly dark in coloration, without the paler space towards tornus characteristic of the species 
of Dipterygia. Type S. subcurva Walk. 
S. tenebrosa Hmps. (15h). Forewing redbrown mostly suffused with black brown; the lines tencbrosa. 
double, black filled in with ochreous towards costa; a blackish patch above inner margin before the 
inner line; the orbicular and reniform stigmata brown with pale annuli defined by black; subterminal 
line shown by pale spots preceded by dark suffusion; a terminal row of minute white points before the 
blackish fringe; hindwing whitish towards base suffused with fuscous, wholly fuscous before termen; the 
veins dark. Described from a single G from the Madras district; the smallest species of the genus. 
S. subcurva Walk. (= postica Walk., calida Walk.) (15 h). Forewing dull dark brown, more subcurva. 
or less suffused with blackish fuscous, except the area towards apex above middle, which usually remains 
brown; the lines, which are distinct only in the unsuffused examples, double, black; the inner oblique and 
waved, preceded by a black streak above inner margin; the outer angled above middle and dentate lu- 
nulate; subterminal line represented by some small redbrown spots, accompanied by white scales, preced¬ 
ed and followed by black streaks, that above vein 4 reaching to the reniform, and that above vein 2 
to outer line; stigmata very indistinct, brown with darker edges; hindwing luteous at base, suffused with 
brownish, becoming broadly brown before termen; the veins and cellspot brown. In this species the 
$$ are somewhat smaller than the GcG the ab. sikkima Moore (15h) has a patch of bluish white scales in sikkima. 
the submedian fold beyond outer line and the extremity of subterminal line beyond it also whitish. Larva 
black, with irregular grey patches streaked with black on dorsum and sides; the head red; spiracles white; 
a large irregular orange patch on dorsum of last segment. Khasia Hills, Assam; Sikkim; Madras; Cey¬ 
lon; Borneo. The form sikkima (of which I have only seen $$) is not restricted to Sikkim, but occurs 
also in Ceylon and Khasia Hills examples. 
S. kebeae Beth.-Baker (15 h). Forewing grey brown, dusted and in parts suffused with black; kebeae. 
the lines black, double, somewhat interrupted; the inner oblique and wavy, preceded by a strong black 
streak on inner margin, especially in the $; outer line sharply angulate, preceded by black suffusion 
above inner margin; subterminal line whitish, interrupted and indistinct, but preceded by deep black 
suffusion below vein 6; terminal spots and veins towards termen black; stigmata very indistinct, the reniform 
externally with pale points; hindwing dark fuscous, the fringe paler. The type from Mt. Kebea, Bri¬ 
tish New Guinea; the description above given was made from specimens in the Tring Museum from 
the Upper Setekwa River, Snow Mts., Dutch New Guinea, and may be a separate species. 
S. commixta Wan. (15h). Forewing brown, speckled and clouded with darker brown, and in commixta. 
parts suffused with brownish fuscous; a slight leaden purplish patch at base of vein 1, and another on 
the same vein beyond outer line; lines black, double at costa, the inner and median partly filled in 
with blackish, the median separating the brown stigmata and sometimes forming a dark patch in submedian 
interspace; a black streak above inner margin before inner line, stronger in the $; outer line strongly 
lunulate dentate; subterminal line pale brown, interrupted, with a pale patch above vein 4, crossed by 
darker streaks above veins 3 and 5, the anal angle and terminal area, especially in the $, suffused 
with darker; terminal black lunules; fringe dark brown; hindwing dark brownish fuscous with the fringe 
paler; in the ab. atribasalis Wan. (15h) the whole of the basal 2 /s, except a narrow strip along inner atribasalis. 
margin, is suffused with black, obscuring all markings; the terminal area and space before anal angle 
being also clouded -with dark. Penang, Malay peninsula. The examples of the aberration are larger 
than those of the type form, and may belong to a distinct species.
