?. Primaries above bright bluish green, with two oblique subbasal stripes and two 
slightly divergent subangulated discal stripes sap-green ; outer border broadly washed with a 
tint of silvery greyish, its inner edge defined by an undulated sap-green line ; inner margin 
tinted with pmky brown, with a large deep rose-coloured tuft at base; fringe yellow, tipped 
with black: secondaries bright rose-red, with pale costal area and broad diffused green 
external area, darkest at anal angle; fringe yellow, dotted with black at the extremities of the 
veins ; extreme base white: thorax bright velvety grass-green ; abdomen sap-green; antennz 
pink. Under surface green, wings crossed by two parallel silvery white discal stripes, 
bounded outwardly by diffused sap-green stripes, the inner one of primaries abbreviated owing 
to its passing into a broad carmine patch, which covers the basal three fifths of the wing 
excepting upon the borders ; anal areas of both wings tinted with lilac-grey, the commence- 
ment of the submarginal undulated line of primaries indicated in this colour: secondaries 
with a third oblique white stripe near the base. Expanse of wings 4 inches 8 lines. 
Darjiling (Lidderdale). 
The only female known previous to the arrival of the present one was so much faded as 
to render its definition impossible ; it had become yellow in tint on both surfaces. It is 
probable that fresh examples of the male would show a similar uniformity of colouring in the 
primaries to that exhibited by the female. 
Triptogon indicum. (Plate LXXXI. fig. 2.) 
Smerinthus indicus, Walker, Cat. Lep. Het. viii. p. 254. n. 17 (1856). 
Primaries above brownish grey, with an olive-brown apical external patch ; four lines 
across the basal area (the second very indistinct), two across the middle, the outer one sub- 
angulated, widely diverging from the inner one towards the costa, and followed by traces of 
a third parallel to it, and a very sinuous discal line, all pale olive-brown ; a blackish dot near 
external angle; fringe grey, spotted with black: secondaries pale ferruginous, whitish on 
costal border ; a white anal patch crossed by a dark ferruginous streak ; frige grey, with two 
or three blackish spots: body brownish grey. Under surface altogether paler; palpi ferru- 
ginous, anterior coxze reddish. Expanse of wings 2 inches 4 lines.
