272 SPHINGID^E. 



two segments of abdomen dark olive-green, with a white fringe 

 to the first segment ; the other segments dark olive -brown 

 with stripes and spots as in nerii. Wings similar in pattern 

 to those of nerii, but very much darker olive-green on both 

 sides ; fore wing with a w T hite spot at apex on upperside and 

 at end of cell on underside ; the white apical line SC 4 -SC 5 , 

 which borders the olive-green triangular patch, not prolonged 

 beyond SC 5 as in nerii. Antenna thicker than in nerii, 

 especially in <$. First segment of hind tarsus as long as tibia 

 and as segments 2 to 5. Expanse : $ 86-110 mm., $ 124 mm. 



<$. Tenth tergite shorter and broader than in nerii ; sternite 

 nearly as long as the tergite, more strongfy chitinized and 

 narrower than in nerii. Large scales of clasper brown or 

 black on midrib and at edge ; harpe (fig. 68 F) shorter than 

 in the other species except layarcli, distal margin angulated, 

 upper margin somewhat flattened, with two rows of teeth. 

 Penis-sheath (fig. 68 G) armed with two slender processes, the 

 left horizontal, the right obliquely curved towards the ventral 

 side. 



$. The distal portion of the vaginal plate nearly smooth ; 

 the chitinized half-ring-shaped plate in front of the vaginal 

 aperture not raised to a carina or ridge. 



Hab. E. Himalayas, S. India, Ceylon and Burma to 

 Malaya and China. We have bred it in the Khasi Hills, 

 where the larva occurs somewhat rarely at an elevation of 

 about 4,000 feet in dense jungle during the rainy season. 



Egg. — As for nerii. 



Larva : — 



Final instar. Head round, body as in nerii ; horn rather long, 

 stout, tapering gradually to near tip where it narrows suddenly 

 to a simple point. Surface of head dull, covered with small 

 tubercles. Body dull and smooth ; horn covered with small 

 tubercles. 



Coloration. — Head green with the tubercles paler. Body : 

 segments 2 to 4 dark green, rest of body paler, brighter green ; 

 a dull green saddle -shaped marking on dorsum of 2 ; a narrow 

 dorso-lateral stripe from front margin of 3 to base of horn, 

 orange on 3 to 5 and on 12, white edged above with dark 

 green on the median segments ; on 4, immediately below the 

 dorso-lateral stripe, a small, shortly oval, transverse ocellus, 

 dark blue above shading to white below ; on 6 to 11, just below 

 the dorso-lateral stripe, a broad, sky-blue stripe, broken at the 

 margins of the segments and thus forming a series of oblong 

 spots ; on the same segments six dark green oblique stripes 

 running in the opposite direction to that which is usual in 

 sphingid larva?. Horn brown with the tubercles paler brown ; 

 anal flap and claspers chocolate ; legs pink. Spiracles oval, 

 yellow with the central slit brown. Length 100 mm.
