the hindwings is the most characteristic point, and affords a ready 

 test for recognition. Of the genera here given Deiopeia is the 

 most ancestral, and approaches nearly to the Hypsidae, from which, 

 the Arctiadae appear to have been developed. One or two genera 

 usually placed in this family, I class (^according to the diagnosis 

 given above) with the Hypsidae. 



The following is a tabulation of the Australian genera. 



1. Forewings 6 absent 24. Hestiarcha.
