11. Genus: Syrastrena Mr. 
The genus only comprises one rather small species, the body of which is densely covered with appressed 
hair, the palpi appearing triangular from the sides and being remarkably broadly scaled, the antennae exhibiting 
also in the $ rather long pinnae, the branches of which gradually grow shorter towards the apex. Forewing 
broad triangular with a steep, in the <$ somewhat more curved margin, hindwing uniformly rounded. In the 
forewing veins 6, 7, 8 on a footstalk, the footstalk of 9 and 10 very long. In the hindwing veins 3, 4, 5 on 
a footstalk, 7 rising near the base, 8 approaching it very closely, 1 or 2 secondary veins. Middle and posterior 
tibiae with short terminal spurs. North India. 
S. minor Mr. (35 b). Uni-coloured light reddish-brown, forewing with 2 parallel, dark, antemeclian minor. 
and postmedian oblique bands proximally bordered with light. Under surface at the apex of the forewing and 
in the hindwing hued grey, hindwing with a narrow brown median band proceeding from the costal margin 
and extending to vein 5. North India (Sikkim). 
12. Genus: Bharetta Mr. 
Antennae with moderately long pinnae, palpi porrect, long, densely scaled. Forewing with at first 
rectilinear costal margin being rather much bent towards the apex, apex sharp, margin below the apex excised, 
projecting again at vein 6, then forming another broad excision as far as vein 2. Hindwing broad, uniformly 
rounded, or excised below the apex. In the forewing veins 6 and 7 forked, footstalk of 9 and 10 not quite so 
long as the free branches. In the hinclwing veins 4 and 5 on a short footstalk, 7 and 8 at the base closely touch¬ 
ing each other, 1 secondary vein. Middle and posterior tibiae with short terminal spurs. Represented by 
2 species occurring in North India. 
Bh. cinnamomea Mr. (35 c) is a medium-sized species of a reddish-grey total colouring, with black cinnamo- 
palpi and a blackish longitudinal streak across the vertex and thoracal dovsum. Forewing with a dark brown mca 
oblique band extending from the apex to the proximal margin, behind which the distal part of the wing is 
somewhat more grey-coloured. A blackish discal spot and 2 blackish subbasal spots near the costal margin, 
besides a series of distinct, blackish submarginal spots. Hindwing with a pale brown oblique band from the 
apex to the proximal margin. On the under surface in the forewing the discal spot is somewhat larger, the 
other spots are absent, the band is indistinct. The band in the hindwing, however, somewhat more distinct 
than above, light ferruginous, in the middle slightly bent. Sikkim: Darjeeling. 
Bh. flammans Hmps. is easily discernible from the preceding by its smaller size, the bright red colour- flammans. 
ing, and the excision of the margin of the hindwing. Forewing with dark bands and a prediscal and post discal 
rectilinear oblique band approaching each other at the proximal margin. Hind wing with a dark reddish-grey 
apex and an indistinct median band. Manipur. 
13. Genus: Odontocraspis Swh. 
In its exterior not at all like a Lasiocampida, the only species of this genus known hitherto at first sight 
strongly recalls some Hesperids, which is also expressed in its name hasora. The rather long-extended, narrow 
forewing exhibits 2 unsealed preapical vitreous spots, the distal margin projects somewhat at vein 6, then follows 
an almost semicircular concavity. The hindwing is also oblong, semicircular with a rectilinear proximal margin, 
only at vein 7 the margin forms a small projection. In the forewing veins 6, 7, 8 forked, the footstalk of 
9 and 10 very long; hinclwing with an open cell, veins 7 and 8 fused for a short distance so that a narrow’ 
secondary cell is produced, from which 2 or 3 secondary veins rise. Antennae remarkably short, with rather 
long pinnae; palpi as in Bharetta long, projecting beak-shaped. Middle and posterior tibiae without terminal 
spurs. 
0. hasora Swh. (35 c). Dark brown, forewing beside the two hyaline preapical spots with irregular hasora. 
black spots between the cell-encl and the vitreous spots, and with traces of a blackish discal and post discal 
band; in the cell a more or less extensive, bright orange-red longitudinal stripe, at the end of the discoidal vein 
dentate white. Marginal scales whitish. Under surface of forewing somewhat lighter with a white discal spot, 
hindwing beneath with a broad, though incomplete, bluish-white transverse band. The species might, especially 
also according to the marking beneath, be considered as a typical model of mimicry. North India (Khasia 
Hills) as far as the Sunda Islands (Borneo).
