■of each lobe to base of antenna, and dorsally from near apex 

 of each lobe to nape ; labrum green ; ligula whitish, the outer 

 edges broadly brown ; basal segment of antenna pale green, 

 second segment black, end-segment pale rusty ; mandible 

 green, tip dark brown. Body green or bluish-green, darker 

 than head ; tubercles white ; a dorsal stripe of black dots on 

 segments 2 to 4, sometimes extending further back as 

 a blackish quadrate patch on the middle of each segment, 

 and always present on 5, where it is surrounded by yellow ; 

 a large, enamel- white, irregular, rounded patch usually present 

 in middle of subdorsal area of 8, with a line of black tubercles 

 along its upper edge ; on one or more of the median segments 

 usually subdorsal patches of varying size and shape, yelloAV 

 ringed narrowly b}^ red- brown ; seven narrow oblique stripes, 

 each running across one segment and a portion of the adjoining 

 segments, pale yellow, sharply defined above by a brown line, 

 ill-defined below, that on 11 broader than the rest and running 

 to base of horn. Horn green, with the tubercles and end- 

 points dark brown ; true legs purplish, prolegs and claspers 

 of body-colour. Spiracles small, those of segments 2 and 



12 larger than the rest, narroAvly oval in shape, colour brown. 

 Length 55 mm. ; breadth 8 mm. ; horn 9-5 mm. ; head 8 mm. 

 long by 5 mm. broad. 



Pupa. — Slender, narrowly rounded in front, slightly tumid 

 in middle ; vertex at right angles to longitudinal axis of 

 pupa, frons slightly ventral and not visible from above ; 

 tongue broad and short, shorter than fore leg ; antenna shorter 

 than fore leg, mid-leg slightly longer than fore leg ; no coxal 

 piece. Surface smooth and shining, segment 2 minutely 

 pitted ; tongue, legs, antennae and thorax superficially cross- 

 rayed ; abdomen coarsely but not deeply pitted except on 



13 and 14 ; sculpturing on 4 consisting of a raised, pear- 

 shaped shining weal, pointed dorsad, on each side of dorsal 

 line, reaching about half-way down the segment and occupying 

 nearly its whole length ; ante-spiracular ridges on 9 to 11 

 consisting of four narrow parallel ridges separated by much 

 wider channels ; spiracle of 2 a low, convex oval weal, the 

 remaining spiracles oval and flush, the central slit with narrow 

 raised edges. Cremaster stout, five-sided, ending in a simple, 

 blunt point. Colour chestnut, a large rounded patch below 

 and in front of eye, and the hind bevels of abdominal seg- 

 ments 8 to 10 pale cream- colour, abdomen darker, cremaster 

 and spiracles black. Length 30 mm. ; breadth 10 mm. 



Habits. — The eggs are laid singly, usually on the underside 

 of a leaf of Quercus fenestrate Roxb., family Fagacese. The 

 larva rests on the underside of a leaf ; when alarmed it raises 

 the head and anterior segments, the head being held so that 

 the long apical processes continue hi the line of the body,
