174 DESCRIPTIONS OF AUSTRALIAN MICRO -LEPIDOPTERA, 



Easily known from the following species by the longitudinal 

 lines, and the absence of the costal blotch. Some specimens are 

 extremely small, apparently the later brood. Taken occasionally 

 at Manly, near Sydney, where the larva is common ; in December 

 March, and May. 



Larva apodal, somewhat tapering posteriorly, pale yellowish ; 

 mines a flat irregular blotch, apparently consisting of a spiral 

 gallery, in leaves of Euphorbia sjparmanni, (EuphotliaceceJ, in 

 February (and doubtless at other times).
