Both sexes with a two-branched subcostal in forewing; costa 

 of forewing straighter in ^; anal lobe moderately well developed, 

 two tails each about ^^ inch to 1st median and submedian of hind- 

 wing. With the exception of Fseiidonotis turneri, the two 

 insects placed in this genus are the only recorded Australian 

 species having two long filamentous tails to the hindwing of 

 approximately equal length; in addition the males both have a 

 large circular discoidal black spot on forewing which at once 

 marks them off. Type H. fmoias, Feld., from the Philippines. 



If the two recorded species can be considered distinct, they 

 may be separated by the males as follows : — 



A. Uppei'side with central areas shining blue, almost disappearing

B. Upperside dark grey somewhat suffused with bluish .. noctula.
