Hah. — Sydney, N.S.W. (on Ficus rubic/inosa; W. W. Froggatt). 



This species is closely allied to the Moreton Bay Fig insect, 

 but is quite different enough to form a new species. The larva 

 and pupa are very different in form and colouration and in habits. 

 The larva always forms a solitary button of sap, under which 

 seldom more than one seeks shelter, the outer surface of the 

 exuded sap being covered with the fine hairs on the under surface 

 of the leaf, and never forming a large irregular mass as on the 

 foliage of F. macrophylla.
