■646 REVISION OF AUSTRALIAN LKPIDOPTEBA, V., 



Antenna! pectinations in ^ 3. Palpi H. Though easily 

 recognised Vjy the structural characters, this seems to be a very 

 variable species. J have two examples before ine, both males, 

 and both fiom Gisborne. The first corresponds generally to Mr. 

 Meyrick's description, but differs in details; the Hrst line is 

 obsolete on one side, on the other very slender and dentate, the 

 discal spot pale-centted, the second line is reduced to streaks on 

 veins, there is a dentate subterminal line in costal area onlj', and 

 the tertninal line is obsolete. The second example is melanic, 

 the greater part of the forevvings is suffused with dark fuscous, 

 and the whole of the hind wings is dark fuscous except for a 

 very slight imperfect subterminal line. The two examples ai"e 

 certainly conspecific.
