576 Mr. E. Meyrick's Descriptions of 



dotted with blackish scales : cilia pale brownish-ochreous, with two 

 indistinct brownish lines. Hindwings grey ; cilia light grey. 



One specimen, unlabelled, but probably from Christ- 

 church (Fereday). This is an interesting addition, the 

 genus Yponomeuta not having been previously recorded 

 from New Zealand ; the present species, though quite 

 normal in structure, differs widely in superficial appearance 

 from any other.
