90 NEW RACES OF AUSTRALIAN BUTTERFLIES 



All the other species of Heteronympha have a well defined sex 

 mark in the forewing of the male — this is absent in cordace. The 

 general appearance of the butterfly does not agree with other 

 species of the genus, which fall naturally into two well defined 

 sections, (a) those with dimorphic females (H. merope and H. 

 mirifica), and (b) the remaining species, which are all very 

 similar, even in the sexes. (//. bariksi, solandri, paradelpha and 

 penelope).

Heteronympha cordace has a fairly wide distribution in south- 

 ern Australia, and occurs also in Tasmania. Specimens from the 

 northern limits of its range where it is essentially a mountain 

 butterfly, are considerably darker than those from Victoria, where 

 it occurs at lower elevations as well as in the mountains. 



Tasmanian specimens are more like Victorian ones, with the 

 exception of those from Cradle Mountain, which are decidedly 

 smaller than specimens from any other locality.
