1875.] SPECIES OF SPHINGIDZ. 251 
that the genus has been wrongly located amongst the Cherocampine ; 
it is, in fact, somewhat allied to Busiana. 
A note, on the original drawing representing the three stages of 
this species, states that it ‘feeds on Amoora Rohituka.”’ 
The female of A. liturata is larger and darker than the male ; the 
primaries are redder and more uniform in colour, the outer marginal 
area alone being distinguished by deeper coloration; the body is also 
darker, with the dorsal line of the abdomen dark brown. 
33, AMBULYX RHODOPTERA, 0. sp. 
d. Allied to the preceding ; primaries with the markings similar 
but less distinct, outer marginal area darker, the entire wing with 
the exception of the marginal area rosy; secondaries rather paler 
than in A. liturata, the mottlings less distinct, the inner transverse 
bar reduced to a line: body rosy, with the usual dark mahogany- 
brown thoracic bands; dorsal abdominal line brown: wings and 
body below rather lighter than in A. liturata. Expanse of wings 
4 inches | line. 
Darjeeling. Type, coll. F. Moore. 
A very pretty and distinct species. 
34, AMBULYX SERICEIPENNIS, 0. sp. 
Primaries silky, of the male whity brown, of the female pinkish 
grey ; a rounded spot at base, a second at basal sixth of costa, and in 
the male a third on interno-median interspace near the base, all dark 
olive-brown, encircled with whitish ; two very irregular parallel brown 
lines crossing the wing before the end of the cell; a black dot on 
lower discocellular veinlet ; a broad grey-margined lunulated discal 
olivaceous band from costa to inner margin, where it becomes tinted 
with slate-colour ; a very indistinct lunulated grey line beyond it; the 
apical patch olivaceous, margined internally and crossed obliquely 
near apex by diffused dusky streaks ; outer margin broadly olivaceous, 
margined internally by a dusky line, within which is a pale yellow 
halo: secondaries much as in the preceding species, paler in the male, 
darker with blackish transverse lines in the female: body of male 
whity brown, of the female pinkish grey with the usual bands dark 
olive-brown; wings below much paler, ochraceous, sparsely mottled 
with grey; primaries with whitish marginal border. Expanse of 
wings, ¢ 3 inches 9 lines, 2 4 inches 8 lines. 
Massuri, N.W. Himalayas (Hutton). Type, coll. F. Moore. 
A very pretty species. 
35. AMBULYX LAHORA, 0. sp. 
Primaries above rosy brownish, base slightly clouded with grey ; 
a large olivaceous spot with a whitish margin at basal fifth of costa ; 
a similar oblique oval interno-median spot near the base ; two irregu- 
lar parallel transverse lines, crossing the third fourth of cell ; a broad 
slightly waved continuous discal olive-brown band ; a lunulated line 
just beyond it and confounded with it towards inner margin; an 
oblique diffused subapical brown litura; outer margin with a broad
