212 SPHINGID^E. 



Coloration. — Face brownish-green dotted with yellow ; 

 a broad, white, subdorsal stripe and a broader white stripe 

 separating the face from the cheek ; behind this stripe the 

 colour dark green with paler green spots and yellow tubercles : 

 the tubercles to which the processes on the vertex are reduced 

 dark yellow. Body bright apple-green, the tubercles yellow, 

 those on the front half of segment 2 of a darker yellow than 

 the rest ; the dorsal line of tubercles green with yellow points ; 

 the oblique stripes broad, very sharply defined, each covering- 

 two segments, that on 5 pale mauve edged above and below 

 by bright red-purple in the lateral area, changing abruptly 

 to yellow tubercles in the dorso -lateral area ; that on 6 formed 

 entirely of yellow tubercles ; those on 7 to 10 similar to 

 that on 5 without the edging of red-purple below ; that on 



11 and 12 pale mauve, edged above and below with red-purple 

 in the lateral area, green with yellow tubercles, edged above 

 with red-purple in the dorso-lateral area, and running across 



12 to base of horn. Horn red-purple, the bases of the tubercles 

 red and the tips yellow ; legs pink, prolegs and claspers pink 

 or green, anal flap edged broadly with yellow. Spiracles 

 oval, mauve, with the central slit black. Length 80 mm. 



Pupa. — Similar in shape to those of the genus Marumba, 

 the head rather small, with frontal ridges as in Marumba, 

 these ridges converging slightly towards the dorsum, the front 

 ends joined by a narrow transverse ridge ; tongue reaching 

 to about the middle of the wing-case, fore leg considerably 

 longer, antenna slightly shorter and mid-leg slightly longer 

 than fore leg. Surface shining, the head rugose ; segment 2 

 superficially rugose ; tongue, antenna, wing- and leg-cases 

 all very superficially cross-rayed, rest of thorax more rugose ; 

 segment 4 with sculpturing consisting of a raised, shining, 

 transverse, median weal, bent first forwards and then back- 

 wards in an S- shaped curve ; the front margins of 6 to 12 

 closely and prominently beaded with shining, quadrate beads, 

 smaller on the venter ; rest of abdomen nearly smooth. 

 Spiracle of 2 with the slit bordered by the slightly raised hind 

 margin of 2 and front margin of 3 ; remaining spiracles oval, 

 depressed, with a narrow raised rim, the central slit with 

 raised edges. Cremaster conical, with a short, widely bifid tip, 

 distal half of dorsal surface and ventral surface rugose, ventral 

 surface with a longitudinal channel. Colour shining chestnut, 

 the wing-cases paler, and the frontal ridges, beading and 

 cremaster black. Length 29 mm. ; breadth 9 mm. 



Habits. — Food-plant : Grewia asiatica, family Tiliacese. 

 The larvae are sluggish and resemble in habits those of the 

 genus Marumba. They do not eat the midribs or the larger 

 veins of the leaves, and their presence can be detected by 

 searching near leaves so treated. The pupa is formed in a 

 cell underground.
