BY OSWALD B. LOWER. 483 



a row of more or less confluent fuscous spots along termen and 

 apical fifth of costa; cilia ochreous-fuscous, becoming ochreous 

 around anal angle. Hindwings greyish-ochreous, becoming 

 fuscous-tinged on costal area, and more ochreous along termen; 

 cilia ochreous, at apex mixed with fuscous. 



Broken Hill, N.S.W.; one specimen, in March. 



Closely allied to P. argocentra Low., but apparently distinct; 

 a longer series may unite them.
