The four .Australian species which the writer has assigned to this genus are 

 clo.selj' aUied to the forms found in Kuro2)e, and have not been assigned here simply 

 through lack of a more apjiropriate j)lace to put them. The first species is related, to 

 C. latus Uzel, the second and third to C. icarus Uzel, and the fourth to C. bicolor 

 (Heeger) .
