REVISION OF AUSTRALIAN LEPIDOPTERA. 

 By E. Meyrick, B.A., F.E.S. 



11. 



As a second instalment, I have taken one of the families of the 

 Geometrina ; and have also added in a supplement such species 

 belonging to the families described in my first papei', as have since 

 come to hand. 



GEOMETRIDAE. 



Fore wings with veins 7 and 8 rising out of 9, 10 generally out 

 of 9, 5 remote from and parallel to 4. Hindwings with vein 5 

 present, 8 anastomosing with or appressed or closely approximated 

 to upper margin of cell near base only. 



I have included together the two groups which I formerly 

 separated as Geomietridae and Acidaliadae, this course being ren- 

 dered necessary by the discovery of structural forms which leave 

 no reliable point of distinction. The family, as it stands, is 

 certainly natural, and, I hope, sufficiently defined. 



The following is a tabulation of the Australian genera : — 



1. Fore wings with vein 10 rising separate 2. 



Forewings with vein 10 rising out of 9 3. 



2. Antennae in ^ bipectinated 11. Heliomystis. 



Antennas in ^ not bipectinated 3. D'dhalama. 



3. Antennae m (J bipectinated 4. 



Antennae in ^ not bipectinated 12. 



4. Antennal pectinations terminating in long 



tufts of cilia 2. Prohlepsis. 



Antennal pectinations not terminating in long 



tufts of cilia 5.
