rounded, tennen scarcely bowed, strongly oV)lique; dark purple, 

 with whitish seinihyaline markings; a sliort broad streak from 

 l)ase of dorsum to mid-disc at ^/, a broad fascia, interrupted by 

 veins, from beneath 1 eosta outwardly oblique, then curved in- 

 waids, nai'rowing, and suffused, to mid-dorsum; a similar fascia, 

 usually narrower and more interrupted, from ^j costa to tornus; 

 and a third similnr fascia from f costa ending opposite mid- 

 termen: cilia dark purple. Hindwings with termen gently 

 lounded; ilark purple; a whitish semihyaline blotch in cell; 

 several similar blotches, variably developed, beyond cell; a sub- 

 tttrminal series of conspicuous yellow or orange spots, the two 

 central spots being displaced towards termen; cilia dark purple. 

 Underside simihir. 



The large size and conspicuous colouring are undoubtedly 

 aposematic. In this, the species differs from all other Austialian 

 GeornetritifH which are protectively coloured; the Terpna gvoix^ 

 imitate tlie bark of trees, while the colour of the majority of 

 species is assimilated to foliage. 



This species varies according to locality, forming local races. 

 In the Cairns district is developed a dark form, the pale blotches 

 being lelatively reduced, especially in the hindwing; and the 

 head, thorax, abdomen, and hindwings being decorated with 

 yellow. In Torres Straits the pale blotches are larger, and 

 3'ellow is replaced l)y orange. At Port Darwin the pale blotches 

 are still further eidarged and confluent, the dark purple areas 

 being reduced to a minimum, the decoration is also orange.
