27.Genus: Gastropacha 0 . 
The typical representatives of this genus the diagnose of which we find in the palearctic part (Vol. II, 
p. 168) are Gastropacha quercijolia L., the well-known copper lappet-moth distributed across the whole 
palearctic district, and G. populifolia Esp., the scarcely less well-known poplar lappet-moth. To the Indian 
fauna belong 2 species occurring in the Himalaya at the northern frontier of the district, thus distinctly showing 
that they are actually strangers in this fauna. One originates from Dliarmsala at the southern frontier of Cashmir, 
the other being known from Sikkim. A third species likewise described from Sikkim must be placed to Steno- 
phylloides. 
\ 
G. undulifera Wkr. (32 c). Body light brownish-grey, wings somewhat darker, strewn with dark brown 
scales. Forewing with a black discal streak and an indistinct prediscal and postdiscal, double, black dentate 
band. Dliarmsala. 
G. divaricata Mr. (32 c). Head, thorax and forewing dark red-brown. Abdomen and hindwing some¬ 
what lighter. Forewing with a blackish prediscal and postdiscal dentate band very much approaching each 
other at the proximal margin; between them 2 more indistinct, shorter bands not reaching the proximal margin; 
a row of indistinct, grey sub marginal; spots. Sikkim: Darjeeling. 
28. Genus: Steiiopliylloicles Hmps. 
Very closely allied with Gastropacha. Palpi long, porrect, antennae at the basal half with rather long, 
behind the middle short pinnae. Forewing long and narrow, costal margin rectilinear, only behind the middle 
moderately bent, margin very oblique, proximal margin short. Hindwing with a very convex costal margin, 
forming a sharp angle at vein 7, margin at first rectilinear and undulate, then passing over into the proximal 
margin in a bow. In the forewing veins 6, 7 and 8 forked, the footstalk of 9 and 10 very long, in the hindwing 
vein 3 Avith 4 and 5 on a short footstalk, 7 connected with 8 by a long transverse vein; numerous secondary 
veins. The only remarkable differences between Stenophylloides and Gastropacha consist in vein 8 being forked 
with 6 and 7 in the forewing and in the angular contours of the hindwing. Beside the typical species sikkima 
Mr. also Gastropacha sinuata Mr. belongs hereto. 
S. sikkima Mr. (33 d). A beautiful, bright reddish-brown species. Proximal margin of forewing and 
costal margin of hindwing light golden brown, and so is also the posterior margin of the thorax and the apex 
of the forewing, though it is not quite so bright. Antennae and palpi blackish, across the head and thorax a 
dark longitudinal streak. Forewing with an indistinct dark discal spot and several, usually very indistinct 
blackish dentate bands, the submarginal one of which is most prominent. Sikkim: Darjeeling. 
S. sinuata Mr. (35 f). Head, thorax and foreAving in the E light, greyish-brown with a somewhat reddish 
tint, abdomen and hindwing more intensely brown, abdomen of the $ pale greyish-brown, the wings like the 
forewings in the <$, the reddish tint a little more distinct. Forewing with an indistinct black discal spot, prediscal 
band very obsolete, postdiscal bands and submarginal band likewise indistinct. Sikkim: Darjeeling. 
S. encausta Hmps. (32 g). Head dark yellow, antennae and palpi brown. Thorax dark red-broAA r n, 
abdomen greyish-broAvn with a reddish dorsum. ForeAving dark brown, costal-marginal part inclusive of cell 
and at the posterior cell-angle obliquely up to the apex intermixed with grey; discal spot black; inner-marginal 
half bright red, in the middle of the proximal margin a dark ochreous-yelloAv spot. Marginal part slightly reddish. 
Hindwing dark brown with a reddish tint, the inner-marginal part grey. Marginal scales with yelloAV tips. 
India: Simla. 
29. Genus: Cosinotriche Hhn. 
The typical species is C. potatoria L. distributed in a great number of forms in the palearctic region 
from Europe to East Asia. As to the diagnose of the genus see Fauna palaearctica, Vol. II, p. 163. Most of 
the oriental species closely approximate C. potatoria in their morphological marks and in the scheme of markings. 
C. laeta Wkr. (33 c). Head, thorax and forewing reddish-brown, abdomen lighter, more greyish- 
brown. Forewing Avith a large, AAdiite, somewhat lustrous silvery discal spot on Avhich the discal transverse 
vein is set forth prominently dark, above it a small Avhite spot; an indistinct, vertical, prediscal and a more 
distinct postdiscal dark undulate line extending very obliquely and bent to the left, reaching at the costal margin
