doubtless been evolved as a protection against northern severity of 



climate. 



The pnpa differs from the Dauaine in being slighter and in the 

 absence of a ridge along segment 7 ; indeed the abdomen is much 

 less swollen as compared to the thorax : there is often a considerable 

 carination along the dorsal line of thorax, a slight lateral expansion 

 of the wings, somewhat emphasised eye-points to the front of head, 

 tubercular risings on the dorsum of abdomen in some species and 

 always a distinct constriction behind thorax. The pupa can move 

 itself from segments i», 10 and some species produce an audible, dull 

 click in doing so. The colour is very generally green, ornamented 

 with gold along the carination of thorax and edges of wings some- 

 times ; but, from the habit of pupation low down near the ground 

 close to dead leaves or in dark places, the green of the chrysalis is 

 changed often to bone-colour with dusky dots, &c. The pups and 

 larvffi are very much ichneumoned. 



The food plants are Grasses including Bamboos and Palms. 



The following table will fix the genus of any larva found :—

pearing as one = Lethe. 



C. Head square with well developed horns.

a^. Laiva brightly coloured yellow, green and, 



sometimes, red Ehjmmas (PI. I. 



Jig. 2). 

 6». Larva of different shades of green Melanitis. 



D. Head square with short, flattened, conical points. Mycalesis.
