1875.] SPECIES OF SPHINGID. 7 
pale rosy whitish bands broader, less distinctly white-edged ; the 
dark markings paler, more olive-tinted ; external angle slate-coloured ; 
apical white spot smaller; secondaries whity brown, with a central 
dark-grey nebula leaving a distinct postmedian in-arched line of the 
ground-colour; beyond and bounding this is a broad, submarginal, 
purplish-brown band ; outer margin broadly pale brown, darker exter- 
nally (the submarginal band and the marginal border both narrowest 
at anal angle): body, with the collar, base, and sides of abdomen 
whitish ; pterygodes olive, head and thorax grey; dorsum of abdomen 
greyish brown; antenne pale ochreous: wings below much like D. 
hypothous, but paler. Expanse of wings 3 inches 7 lines. 
Queensland (Janson). ‘ Type, B.M. 
Genus Percesa, Walker. 
11. PERGESA AURIFERA, 0. Sp. 
Primaries olive-green, base transversely spotted with black; a 
violet-centred black spot at end of cell, and from it to inner margin 
a nebulous dusky bar; disk more or less clouded with reddish, 
crossed obliquely from costa to inner margin by three parallel rows 
of black spots; three large costal subapical black spots; outer 
margin pearly, irrorated with black ; fringe dull ochraceous ; secon- 
daries black-brown, costal area pale brown; an anal, submarginal, 
cuneiform, dull ochreous fasciole: body olive-green, head margined 
with whitish; pterygodes grey, black-bordered ; abdomen with two 
longitudinal series of black dots, a lateral golden-yellow streak from 
second segment, and a broad, undulated, golden-yellow lateral border, 
each undulation with a central black dot: wings below nearly as in 
P. castor, but the black lines and dots heavier. Expanse of wings 3 
inches 5 lines. 
Sikkim (Whitely). Type, B.M. 
Var. Primaries and body clay-colour, with a slight greenish tinge. 
North India (Janson). B. 
Allied to P. castor, but differing (besides colour-characters) in 
the much more acute falcate form and greater width of the primaries. 
Genus Cu#rocampa, Duponchel. 
12, CHHZROCAMPA MACROMERA, 0. Sp. 
Nearly allied to C. elpenor, but much larger, the primaries duller 
in colour, with the outer margin more broadly rosy lilacine ; secon- 
daries with more than half the wing rosy; body with the dorsal 
rosy line less defined ; wings below with the costal ochraceous border 
duller, much narrower, only clearly represented towards base ; trans- 
verse band converted into two narrow parallel lines. Expanse of wings 
3 inches 4 lines. 
Silhet (Macgillivray), North India (Stevens). Type, B.M. 
Noted by Mr. Walker as a variety of C. elpenor; I am satisfied, 
however (from the fact that the more nearly allied Japanese species 
is now proved by breeding to be distinct), that it is a different 
species. :
