208 SPHINGID^. 



paler- coloured tubercles ; of body, markings and tubercles 

 as in the 5th instar, except that the ^ subspiracular line of 

 tubercles and the oblique stripes on segments 6 to 10 are 

 formed of very small tubercles, and that the tubercles on 

 dorsal and ventral surfaces of horn are shining black. 



5th instar. Head rounded- triangular, very broad above the 

 mouth-parts, dorsal line hardly depressed ; apical processes 

 of earlier instars reduced to a large, low, rounded tubercle 

 on the apex of each lobe ; clypeus about one -third length of 

 head, no false clypeus ; labrum as broad as clypeus, narrowing 

 frontad ; ligula not so broad as labrum. Surface of head 

 shining, covered with unevenly-spaced, large, low, rounded 

 tubercles, these tubercles smaller and more widely spaced 

 on vertex and cheek. Body : segment 2 of greater diameter 

 than head, its front margin raised into a sharp ridge ; rest 

 of body nearly cylindrical (but the venter somewhat flattened 

 when full-fed), tapering slightly to 12. Horn short, stout 

 at base, tapering sharply to a point, slightly down-curved. 

 Surface of body dull ; a shining, small, rounded tubercle on 

 each side of the dorsal line on the frontal ridge of segment 2 ; 

 a pair of larger and more pointed tubercles, one above the 

 other, below this tubercle, and from the lower tubercle of the 

 pair a continuous ridge, from which rounded tubercles rise, 

 to the level of top of spiracle ; smaller, widely spaced tubercles 

 along the secondary rings of all the segments from 2 to 12 ; 

 a larger tubercle on the subdorsal line of 3 and 4 ; a sub- 

 spiracular line of large wart-like tubercles, each with three 

 or four rounded points, starting from just below and behind 

 the spiracle of 2 and meeting the front end of oblique stripe 

 on 5 at a sharp angle ; oblique stripes on 5 to 11 formed of 

 a ridge, broken by the junctions of the secondary rings into 

 oblong tubercles. Horn covered with shining pointed tubercles ; 

 anal flap edged with rounded tubercles. 



Coloration. — Head dark bluish-green, immaculate ; the 

 tubercle on apex of each lobe yellow ; labrum, ligula and basal 

 segment of antenna pale yellow ; rest of antenna chestnut ; 

 mandible pale chestnut, tip darker chestnut. Body green 

 above the spiracular line, bluish-green below it, segments 2 to 4 

 darker than the rest ; tubercles and ridge on front margin 

 of 2 orange, remaining tubercles on 2 yellow ; those on the 

 remaining segments pale yellow above the spiracular line and 

 of the body-colour below it, the four larger tubercles on the 

 subdorsal line of 3 and 4 nearly white ; subspiracular line of 

 tubercles on 2 to 4, and oblique stripes, shining white, the 

 oblique stripes on 5 and 11 slightly more prominent than the 

 rest ; oblique stripes edged above with dark green, and each 

 stripe runs on to the adjoining segment in front and behind, 

 not reaching the dorsum, the forward and backward extensions
