tip of segment, but the tuft tliiis formed slioiler tlitiii the last two segments 

 together. Tiliiae siiiipk, longer than the respective first tarsal segments ; these 

 little longer tlian the cell of the hindwiiig is broad; spur of foretibia about half 

 till' icngtii of tiic tibia ; those of mid- and hiudtibia very short, long terminal one 

 of liindtibia about half as long again as the tibia is broad ; paronychium witli 

 two lobes (in each side ; pulvillus jircseid. Frenulum and retinaculum present. 

 Underseales of abdominal tergites partly s{)iniforni. 



S . I'/iglith sternite simple ; clasper redueeil, without friclion-patcli ; harjie 

 strongly developed, the apical process double or simple, in the latter case (Ju/ionia) 

 l)re(-eded by several teeth (PI. XXXIV. f. 23). 



?. Vaginal jilate differently armed in the two species of which this sex is 

 known. 



Early stages known only of ('. t(tt'irhioi:i ; of the same type as in Sphinx 

 ocellata. 



Hah. Nortli India to Amurlaud and .lajian, and the larger Sunda Islands. 



The four species resemble one another in pattern, all having an obli(jue line or 

 band on the forewing crossing the apex of the cell and then running along Bl- 

 towards hinder angle, and an oblique apical line, the hindwing being red, tlie 

 posterior half of the mesothoracic tegula being pale like the side of the metanotum, 

 and the abdomen having a dark mesial line.

c?2. One of the finest Sphingids. The green colour of tlie forewing often 

 fading into dayish. D^ of the hindwing in most specimens longer than K'. The 

 lobes of tiie paronychium long. 



c?. Tenth tergite (PI. XXII. f. l(i) weak, pale, gradually narrowed distad, 

 ai)ex more strongly narrowed and mesially feebly sinuate, the surface more or less 

 concave, rough with bristle-bearing tubercles distally, the mesial line raised to a kind 

 of carina ; tlie proximal part of this supra-anal plate (namely the nintli tergite) 

 more strongly chitinised and densely clothed with long hair-scales which project 

 beyond the end of the tenth tergite ; the tenth sternite reduced, without a lobe. 

 Clasper narrow (PI. XXXIV. f. 19), tapering to apex, which is rounded ; harpe 

 strong, rounded ventro-distally, produced into a long and a short, curved, j)ointed 

 process ; on a fold of the clasjier, dorsally of the hari^e, there is a dense clotiiiug of 

 spine-like bristles. Penis-sheatli without armature.
