On some new Indo-Malayan Sphingide. | 479 
LXV.—Preliminary Descriptions of some new Species and 
Subspecies of Indo-Malayan Sphingide. By Lord 
Roruscuitp, F.R.S. 
THESE Sphingide form part of collections sent to the British 
Museum by Major F. B. Scott and Mr. C. J. Brooks. 
1. Ambulyx liturata obliterata, subsp. n. 
3. Differs from /. liturata in its much paler coloration and 
the almost complete obliteration of the minor markings of the 
fore wings and the great reduction of the markings of the 
hind wings. Head, thorax, and abdomen much paler, buffish 
not so vinaceous as in J, liturata. Fore wings stramineous 
buff, tinged with rosy cinnamon, not vinaceous brown as in 
the typical form; the rufous-brown bands on veins 4, 6, and 7 
absent and the rest of the nervures much less distinct, the 
dark bands running in from costa absent, only the one 
crossing vein 6 slightly indicated, the olive patch on vein 1 
and the smaller one above vein 2 both very much larger than 
in 1, iturata ; subtornal patch larger, better defined vinaceous 
mauve, and without the streaks present in J. ’twrata. Hind 
wing paler, yellower, less suffused with rufous, the red 
freckling and median band much reduced. 
Hab. Lebong-Tandai, Benkoelen District, Sumatra, 1912- 
1919 (C. f. Brooks) ; 1 &. 
2. Oxyambulyx pryert sumatranus, subsp. n. 
?. Differs from pryeri pryert in the presence strongly 
marked of a crenulate median black band and an ante-median 
angled line from cell to inner margin. The black basal 
patch and the black transverse bands on hind wing are also 
more strongly developed. 
Hab. Lebong-Tandai, Benkoelen District, Sumatra, 1912- 
1919 (C. J. Brooks); 19. 
3. Clanis brooksi, sp. n. 
&. Nearest to bilineata, Walk., and stenosma, Rothsch. & 
Jord., but apparently much larger; this g having the fore 
wing 70 mm., equalling the 2 of stenosma, and as in all the 
known species the ? ¢ are larger than the gg, the ? ? of 
brooksi will probably prove to be much larger. The pale 
area running in from the costa on fore wing much longer 
than in bilineata, but not so long as in stenosma, not reaching 
second line, first and second lines much straighter, not angled 
and crenulated. Black area of hind wing less extended
