a large brood they may be seen in enormous numbers often 

 along* the midrib and usually on the under side of the leaf. 

 Length of cocoon 11-13 millimeters. Width 5-7 millimeters. 

 Length of contained pupa 7-8 millimeters. 



On first changing into the pupal state it is of a light 

 yellow becoming later a darker hue, and just before the 

 moth emerges the wings change to a dark brown. There 

 are nine visible dorsal segments. The segments 3-7 each 

 have a comb of teeth which extend about halfway on eith- 

 er side of the centre of the dorsum. The moth makes its 

 escape by forcing up one end of the cocoon attached to the 

 leaf, leaving the empty pupa case partially extruding.

Life History. 



The first brood is between the months of November and 

 February. As the higher trees are usually chosen first 

 it is usually impossible, on account of the small number of
