472 SPHINGID^. 



stripe ; a narrow dorso-lateral stripe on 2 to 4 ; the ocellus 

 with some white dots in the green portion of the pupil, the pupil 

 edged narrowly with first white and then green ; oblique 

 stripes on 6 to 10, pale blue crossed by short dark blue lines ; 

 horn of medium length, somewhat square in cross-section, 

 straight to near tip, then bent downwards, hardly tapering, 

 upper surface dark purple, lower surface brown. 



5th instar. Shape similar to that of larvae of the genus 

 Theretra, with segment 5 considerably swollen. Head smooth 

 and moderately shining. Body smooth and dull. Horn 

 held at an angle of about 45° to body, of medium length, 

 somewhat flattened laterally, tapering gently to a slightly 

 bulbous tip, tip bent slightly downwards ; surface dull and 

 smooth except for small round tubercles on the dorsal surface. 



Coloration. — Head and segments 2 to 5 pale sap-green, 

 rest of body pale yellow dor sally, becoming pale blue dor so - 

 laterally and pale grass-green dotted with darker green laterally 

 and ventrally ; a very narrow, dark green dorsal stripe, dis- 

 appearing in the middle of each segment, from 2 to base of 

 horn ; a narrow white dorso-lateral stripe on 2 to 4 ; a large 

 oval ocellus on 5, the front edge encroaching on to 4, long 

 axis inclined backwards and slightly upwards, pupil dark 

 blue in front, sap-green behind, the green containing one large 

 and several small white spots, the pupil edged broadly below, 

 narrowly elsewhere with pure white, this again edged narrowly 

 with sap-green ; a bright yellow patch on dorsum between 

 the ocelli, and running forward on to 4 ; broad, pale chalky- 

 bluish oblique stripes on 6 to 10, that on 10 running through 

 the spiracle on that segment and crossing 11 and 12 to base 

 of horn, all edged above with sap-green ; a dorso-lateral 

 lunule formed of pale bluish spots ringed with dark green on 

 6 to 10, the lunules curved convexedly dorsad and forming 

 backward extensions to the upper edges of the oblique stripes. 

 Horn reddish-purple, the tubercles black ; legs pink. Spiracles 

 white edged with dark green. Length 85 mm. ; breadth 

 11 mm. ; horn 5 mm. 



Pupa. — Tongue-sheath projecting considerably in front of 

 head, semicircular in side-view ; head with frons sloping 

 steeply downwards, and between it and upper edge of base of 

 tongue- case there is a sharp transverse dorsal ridge ; from 

 the lower edge of the tongue-case the ventral surface is concave 

 to the middle of wing-case, then convex to tip of wing-case, 

 the curves being more strongly developed than in others of 

 the genus. Surface dull, tongue-sheath coarsely rugose, 

 veins of wings and legs prominent and set with tubercles ; 

 rest of body smooth. Spiracles white with a broad black 

 band across the middle. Cremaster triangular, upper surface
