length of clypeus ; ligula as long as labrum ; eyes 1 to 4 

 equidistant, forming a quarter circumference of a circle ; 

 6 in line with 3 and 4 and twice as far from 4 as 4 is from 3 ; 

 5 forming an equilateral triangle with 4 and 6. Surface 

 shining, set widely with low, minute tubercles. Body gently 

 tapering frontad from segment 7. Horn long, straight, thick 

 at base and tapering evenly to a blunt point. Surface dull ; 

 secondary rings of segments 2 to 4 raised into ridges on 

 dorsum ; horn covered densely with small pointed tubercles ; 

 large, round, closely-set tubercles on anal flap and claspers. 



Coloration. — Head bluish-green with a broad, pale yellow 

 cheek- stripe from vertex to base of antenna ; false clypeus 

 dark green ; labrum and ligula rust -coloured ; basal segment 

 of antenna dark brown, other segments rust- colour ; mandible 

 pale orange, tip black. Body rich bright green with a glaucous 

 suffusion on dorsum ; oblique stripes white or yellow, each 

 crossing two segments and spreading into a more or less well- 

 defined patch round the spiracles. Horn, anal flap and claspers 

 green. Legs pale orange, base rose-coloured and a black ring 

 on each segment ; prolegs green. Spiracles reddish-brown 

 with a white central slit widening slightly at top and bottom, 

 the whole ringed with yellow, oval in shape and flush. In 

 some specimens there are carmine patches round the spiracles, 

 above the oblique stripes and at bases of true legs. Length 

 70 mm. ; breadth 11 mm. ; horn 8-5 mm. 



Pupa. — Ambulicine in shape, rather like that of Marumba 

 dyras, thickest in the middle ; shoulders evenly rounded ; 

 dorsum of segment 2 very steeply inclined, rising nearly at 

 right angles to the axis of the body, the dorsal line of 3 being 

 nearly parallel with the axis ; tongue equal to fore leg, reaching 

 to about the middle of wing-case, mid-leg longer, antenna 

 slightly shorter than fore leg ; no coxal piece. Surface 

 shining, irregularly corrugate on the head and thorax, 

 elsewhere pitted with coarse shallow pits, except on 

 wing-case ; ante-spiracular ridges on 8 to 10, in the form of 

 three short parallel ridges on each. Spiracle of 2 crescent- 

 shaped ; the remaining spiracles oval. Cremaster stout, 

 ending in a short bifid tooth ; the dorsal surface very rugose 

 except for the tooth, which is smooth. Colour chestnut to 

 blackish -brown, the bevels of the free abdominal segments 

 paler ; the spiracles brown. Length 48 mm. ; breadth 14 mm. 



Habits. — Eggs laid singly on the underside of a leaf in 

 evergreen or semi -evergreen jungles, often on the edges of 

 streams. In the Kanara district the food-plants are Olea 

 dioica Roxb. and Linociera malabarica Wall. In the 

 Khasi Hills the larva feeds on Ligustrum robustum Bl., and 

 in S. China on the same bunh and also on Fraxinus Linn.,
