FAM. GEOMETRIDZE 39 
The moths which we include here should be divisible into at least two or three genera, but as we 
have not been able to find sharp lines of demarcation we have left them together. By subdividing the 
genus into subgenera, we have drawn attention to the variability of certain characters, which may be 
correlated with some real biological divergence. 
Type of the genus : Terpna haemataria, Herrich-Scháffer (1856). 
Geographical distribution of species. — Indo-Australian.
