pale yellowish-green, head light brown with dark brown 
inverted V. Pupa similar to that of ancilla, but larger. 
Pupal duration in October and November averages 22 
days. Larvae are difficult to rear in captivity. Pupae 
may be obtained by enclosing larvae on the food-plant in 
mosquito net, dried leaves being provided for them to 
pupate in. 
Hesperilla donnysa icaria, Waterhouse, 1941. 
The food-plant of this race at Burleigh is Gahnia 
erythrocarpa R. Rr., growing in swampy areas. Larvae 
appear to be more common on those clumps growing well 
out in the open, away from all shelter and shade. 
Hesperilla picta , Leach. 
The food-plant at Burleigh is Gahnia Clark ei Beni. 
This also grows in swampy areas. The larvae appear to be 
more common on those clumps growing in shady and 
sheltered spots. ( Tisiphone abeona morrisi also prefers 
this species of Gahnia.) 
Hesperilla ornata , Leach. 
The food-plant at Burleigh is Gahnia aspera Spreng., 
growing in or near patches of rain-forest. 
Hesperilla idothea, Miskin. 
This species occurs on Springbrook at over 2,000 feet. 
The food-plant is a very tall, coarse Gahnia (G. tetragono- 
carpa Boeck).
