Lepidoptera from New Guinea. 489 



half broader and marked with dark fuscous ; cilia reddish-brown, 

 tips pale ochreous. Hind wings with hind margin angiilated in 

 middle, forming a moderate triangular projection; colour and 

 cilia as in fore wings ; a small white grey-circled discal dot ; a 

 straight line, as in fore wings, from middle of costa to middle of 

 inner margin ; a fuscous-reddish hind-marginal line. 



Port Moresby (Koivald) ; one specimen. Closely allied 

 to T. arentiaria, of which it might possibly be a form, 

 but the differences in cilia and ground colour separate it 

 from any specimens which I have seen.
