MARUMBA. 187 



tubercles on segments 2 to 4, and seven oblique stripes of large 

 tubercles, the lower part of the stripe on 5 widening into a patch 

 of still larger multi-pointed tubercles above the spiracle ; 

 the oblique stripes extend backwards to dorsum and forwards 

 (except the anterior one) well on to the segment in front ; 

 the stripe on 10 very inconspicuous, being formed of smaller 

 tubercles than the others, that on 11 strongly marked. Horn 

 covered with pointed tubercles. 



Coloration. — Head bluish-green with white tubercles, and 

 a white stripe from the apex of each lobe to base of antenna. 

 Body bluish-green of various shades, the tubercles brown or 

 reddish, with white tips, the dorso-lateral stripe and oblique 

 stripes formed of mauve or yellow tubercles on a white ground. 

 Horn green with paler tubercles ; a pale ventral stripe from 

 segment 5 to the claspers. Spiracles oval, blue or mauve 

 in colour. Length 120 mm. ; breadth 19 mm. ; horn 13 mm. 



Pujja. — Similar to those of others of the genus. 



Habits. — Food-plants : Quercus Griffithi Hook. f. & T. and 

 Q. serrata Thunb., family Fagaceae. The habits of the larva 

 are the same as those of other Marumba larvae. The larva 

 is often found with a number of small black flies sitting on it. 

 but they do not appear to cause any ill effects. Larvae were 

 common on the oaks growing in gardens, but were difficult 

 to rear to the imago stage, hibernating pupae usually dying.
