certainly distinct from G. ochrocepliala, Me}^., and G. nereiR, 

 Meyr., whicli probably feed on other species of Acacia. 



LiTHOCOLLETIS, Z. 



Head roughly tufted on crown, forehead and face smooth ; no 

 ocelli ; tongue moderate. Antennpo nearly as long as forewings, 

 slender, filiform. Maxillary palpi obsolete. Labial palpi rather 

 short, straight, drooping, second joint smooth, terminal joint 

 pointed. Forewings elongate, moderately narrow, pointed. 

 Ilindwings narrowl}^ lanceolate, less than half forewings, cilia 

 four times as broad. Posterior tibiae hairy above and below. 

 Forewings with 7 veins, 3 branches to costa, cell closed, 1 simple^ 

 Hind wings without cell, median two-branched. 



Larva fourteen-legged, mining blotches in leaves. Pupa naked 

 or in a cocoon, always enclosed in the mine. 



The species here described is not truly Australian, or at any 

 rate does not belong to the indigenous fauna, so that my remarks 

 on this subject remain in force ; it has been introduced with its 

 foodplant. The genus is readily distinguished from Gracilaria, 

 to which it is most allied, by the tufted head and simpler neuration, 

 in respect of which this species is perfectly typical, the venation 

 not differing in the least from that of European species.
