1875.] SPECIES OF SPHINGIDE. 253 
a greyish patch; outer margin red-brown; a black dot on lower 
discocellular, enclosed in a pale testaceous streak, which runs from 
within cell, just above the third median branch to outer discal bar : 
secondaries rosy brick-colour, costa testaceous, anal angle grey ; two 
pale postmedian brown streaks from anal angle to discoidal nervure, 
outer margin and an abbreviated lunulated discal streak dark brown, 
bordered within with pale rosy : thorax chocolate-brown, testaceous 
at the sides; abdomen whity brown: wings below rosy, crossed by 
two parallel discal brown lines, outer margin dark brown ; primaries 
with an oblique line from apex to lower discoidal nervure, subapical 
area lilacine, base and inner margin testaceous: thorax below deep 
foxy red, especially the palpi and prothorax ; abdomen deep rose-red. 
Expanse of wings 3 inches 7 lines. 
Kunawur, N.W. Himalayas (Lang). Type, coll. F. Moore. 
This is a very pretty little species; the larva, according to Capt. 
Lang, feeds on poplar. 
Genus Triptocon, Bremer, 
Bull. de Acad. Imp. St. Pétersb. iii. (1861). 
Allied to Metamimas ; primaries not angulated below apex; all the 
wings regularly undulated from apex to external angle ; under surface 
of discoidal area of primaries densely scaled so as to obscure the dis- 
cocellulars; upper discocellular of secondaries rather longer than 
lower, conxex, lower oblique; palpi short, obtuse ; antennze long, of 
male strongly pectinated. 
Type T. dissimilis, Bremer. 
38. TRIPTOGON GIGAS, N. sp. 
Allied to 7. sperchius, rather larger ; primaries above paler, except- 
ing at centre of outer margin; a blackish discocellular spot; four 
transverse basal lines well defined : secondaries red-brown (as in T. 
dyras) ; anal angle paler, with two obliquely placed small brown 
spots: primaries below with central transverse lines less distinct ; 
secondaries whity brown, excepting at anal angle (which is tawny) 
three nearly equidistant red-brown lines. Expanse of wings 5 inches 
5 lines. 
3 2, Silhet (Stainsforth). Type, B.M. 
39. TRIPTOGON CRISTATA, N. sp. 
Wings and body above dull clay-brown, clouded with slaty grey ; 
primaries crossed by seven dark brown lines, the third and fourth 
(but especially the latter) well defined, oblique, and nearly straight ; 
the lines arranged much asin T. gigas, but the third and fourth 
nearer together; the spot near external angle olive-brown, not well 
defined ; a pale spot on lower discocellular vein : secondaries nearly 
uniform in colour, but rather darker towards apex, browner on ab- 
dominal area, and very slightly paler at anal angle, where there is 
also an olive-brown spot: body with a well-marked dark central 
longitudinal crest from the front of the head to near the end of ab- 
domen ; antennse whity brown: wings below brighter-coloured than
