134 SPHINGID^E. 



Coloration. — Head immaculate glaucous-green. Body green, 

 so suffused with white on dorsum that only a narrow dorsal 

 stripe and a stripe forming the upper border to the longitudinal 

 line of tubercles remain green ; below this line paler green ; 

 venter green suffused with white and a rose-brown, white- 

 speckled ventral band ; tubercles on body white ; a very 

 faint whitish subspiracular stripe on segments 3 to 5, joining 

 the lower end of the oblique stripe on 6 ; similar coloured 

 oblique stripes on 6 to 11, that on 1 1 running back across 

 12 to base of horn. Horn bluish in colour, the tubercles on it 

 brown or livid. Legs opaque pink, each segment banded 

 narrowly with white at its base ; prolegs green speckled with 

 white ; anal flap and claspers glaucous-green, both edged 

 narrowly with white. Spiracles oval, azure-blue, the upper 

 and lower ends shortly whitish, suffused with purplish on each 

 side of the blue central slit. Length 95 mm. ; breadth 14 mm. ; 

 horn 13 mm. 



Pupa. — Shape similar to that of others of the genus ; coxal 

 piece wanting. Surface shining ; frons and vertex smooth 

 medially, rugose laterally, and clothed with minute hairs, 

 a peculiarity we have not noticed in other sphingid pupae 

 except Hippotion echeclus ; thorax coarsely and irregularly 

 corrugate ; abdominal segments with deep pits at the bottom 

 of shallow, wide depressions ; sculpturing on segment 4 two 

 transverse channels on each side of the dorsal line, having 

 -a raised triangular area between them ; costal margin of wing 

 beaded, veins prominent and beaded ; base of tongue tuber- 

 culate ; a large, prominent horn-scar on segment 12 with 

 a transverse furrow behind it ; proleg scars prominent ; 

 clasper scars large, smooth and shining. Spiracle of 2 covered 

 by a lobe projecting from front margin of 3, leaving the central 

 slit visible between it and hind margin of 2 ; remaining 

 spiracles oval, shining, the narrow central slit with raised 

 -edges. Cremaster wedge-shaped, base undercut, two pro- 

 jections from its lower edge meeting two projections from 

 venter of segment 14 ; tip bluntly bifid ; surface very deeply 

 rugose excepting tip. Colour dark chestnut, hind bevels of 

 segments 8 to 10 brighter, spiracles black. Length 55 mm. ; 

 breadth 15 mm. 



Habits. — Food-plant : Terminalia tomentosa Bedd., family 

 Combretaceae. This is a large timber-tree, and the few larvae 

 found were, with one exception, on the topmost branches at 

 a height of 80 feet or so from the ground. No eggs were found. 

 The larvae eat the leaves of the food-plant completely except 

 for the midribs, which they then, curiously enough, eat through 

 at the base so that they fall to the ground. The fallen mid- 

 ribs and the frass reveal the presence and position of the 

 larvae, which are otherwise very difficult to locate.
