ceded by antimony-yellow (xv) faint lunules and some scales of same colour, 
beyond it above lower median and as far as discocellulars, beginning at |rd 
of costa, then well curved outwardly and then obliquely inwardly to inner 
margin, where it ends in a few antimony -yellow scales at base of first scale 
tooth; postmedial line blackish and followed by irregular antimony -yellow 
lunules and with some similar scaling before it between 2-4, and 5-6 and again 
beyond it between veins 3—4; the line begins at frd of costa, runs then nearly 
parallel to costa for half the distance to apex, then oblique and nearly straight 
to base of second scale-tooth, very much dentated outwardly at veins 2-8; 
sub-terminal line represented by a series of black spots between veins 3-8, 
preceded by some yellow scaling; cilia of ground colour, but with a lighter base. 
Hind wing cartridge-buff (xxx), exterior half gradually shaded with hair-brown, 
most intensely at outer margin; cilia cartridge-buff, tinged with hair-brown. 
Under side: tarsi cartridge-buff ringed with bone-brown; fore wing uniform 
hair-brown; cilia hair-brown at base, then bone-brown and with a few cartridge- 
buff scales between the veins indicating a semilunar line ; hind wing as on upper 
side.

$. Proboscis very rudimentary; palpi short, scarcely as long as width 
of eye, porrect; first and second joints of equal length; third joint frd of second, 
globular, covered with long, spreading hairs; eyes large, rounded, glabrous; 
antennae bipectinate as in Centra but branches shorter, about four times shaft, 
gradually getting shorter towards tip; basal part of shaft as in Cerura\ fore 
tibia with a process as in Centra but slightly shorter and more straight; mid 
tibia with two terminal pointed spurs of about fth of tibia in length; hind 
tibia with two pairs of pointed spurs about frd of tibia in length; spurs 
rather long and thin, with two very short rows of short teeth near apex only; 
all legs covered with long, spreading hairs; tarsi with hairs and scales; mid 
and hind tibiae with small scale tufts at middle and terminus. 
Fore wing rather long and narrow; costa evenly incurved; apex rounded; 
termen oblique, evenly curved; tornus well rounded; inner margin somewhat 
lobed near spur of 1 b\ 1 b with a fork at base and a spur which, however, does 
not reach inner margin; 2 from |th lower median; 3 from fth distance 2 to 4; 
4 from lower angle; 5 rather weak, from above middle of discocellulars and with 
an indication of a continued veinlet in the cell; 6 from end of areole, which is 
nearly 4 times the breadth; 7 from frd stalk of 8, 9; 8 and 9 on a stalk of frd 8, 
originating from end of areole; 10 from just before end of areole; 11 from frd 
upper median, somewhat curved inwardly near areole; 12 parallel to costa. 
Hind wing sub-triangular; costa nearly straight; apex rounded; termen well 
rounded; tornus with a rounded lobe at 1 b; inner margin evenly curved; 1 a 
and 1 b nearly straight ; 2 from lower median at frd ; 3 and 4 from lower angle ; 
5 faint, but distinct, from well above middle of discocellulars; discocellulars 
oblique and faint; 6 and 7 on a stalk of nearly half of 6; 8 a little upcurved 
till frd upper median, where it has a little bulge to suggest rudiments of a bar, 
then approximated and parallel to near end of cell, then upcurved towards 
costa.
