"90 SPHINGIDJE. 



narrowing frontad ; ligula semicircular in shape ; eyes 1 to 4 

 in a gentle curve, 1 about one eye-diameter from 2 ; 2,3 and 4 

 closer together ; 6 in line with 3 and 4, about one diameter 

 from 4 ; 5 rather more than one diameter from 4 and 6 ; 5 smaller 

 than the rest, which are co-equal. Body long and slender, horn 

 very long, thick at base, tapering gently to near tip, then 

 becoming broader and flattened above and below, dividing 

 into a blunt fork, the arms rounded and setiferous ; the end of 

 the anal flap tumid. Surface of head and body dull and smooth, 

 each secondary ring set with large, smooth, low, oval tubercles ; 

 on segment 2 a transverse row of six larger tubercles on the 

 front margin, a row of six on the hind margin and a row of 

 four between these two roAvs ; on 3 a very large, fleshy, sub- 

 dorsal, conical tubercle, and on 4 an equally large but more 

 rounded dorso-lateral tubercle ; on 14 a similar but smaller 

 one on each side of the dorsal line, the tubercles on 14 each 

 bearing two setse, one behind the other ; horn closely set 

 with conical tubercles. 



Coloration. — Head green with a broad yellow cheek-stripe 

 from near vertex to base of antenna ; labrum and ligula 

 whitish-green ; basal segment of antenna white, the others 

 pale green ; mandible pale green at base, rust- coloured in 

 middle and black at tip. Body green, the tubercles yellow, 

 giving it a mottled appearance ; oblique stripes on segments 

 5 to 11, each extending backwards to near the dorsal line of 

 the adjoining segment behind, that on 11 broader than the 

 rest and running to base and for a short distance up the side 

 of the horn, the stripes white near each spiracle, yellow 

 behind it, and edged broadly above with dark green. Horn 

 dark blue with tip paler blue, a crimson stripe up the side from 

 base touching the upward extension of the oblique stripe and 

 extending higher up the horn ; tubercles on dorsum of horn 

 black ; anal flap edged with yellow. Legs, prolegs and 

 claspers green. Spiracles large, oval, white with a broad 

 reddish-brown band across the middle, the whole with a narrow, 

 green rim. Length 60 mm. ; breadth 7 mm. ; horn 12 mm. 



Pupa. — Body slender and sharply pointed ; the free tongue - 

 sheath very thin up to the clubbed tip, its base directed for- 

 wards in the same line as the axis of the body, the sheath 

 then turning in a high arch, the clubbed tip reaching to middle 

 of wing-case, where it touches the ventral surface of the pupa ; 

 eye rather prominent, and just behind it the dorsal surface 

 of the pupa rises first steeply and then gently to the middle 

 of the body, forming a kind of step ; antenna mid-way in 

 length between fore leg and mid-leg in both sexes ; coxal 

 piece very narrow. Surface shining ; head prominently 

 corrugate-rugose, tongue-sheath transversely ridged ; veins
