264 REVISION OP AUSTRALIAN TORTRICINA, 



Antennae in cf simple or shortly ciliated. Palpi moderate, 

 porrected or more or less ascending, second joint with more 

 or less projecting scales above and beneath, terminal joint 

 short or moderate. Thorax with posterior crest. Forewings 

 with 7 and 8 separate, 7 to termen. Hindwings with 3 and 4 

 connate or seldom stalked, 5 approximated ai. base, 6 and 7 

 closely approximated towards base. 



The genus is a very large one, but especially characteristic of 

 the northern hemisphere; it is hardly represented in the true 

 Australian fauna (only by the two quite peculiar species A. 

 endophayd and A. gunomela), but forms a prominent feature in 

 the Indo-Malayan element which enters by way of Northern 

 Queensland. The males of many species show curious folds and 

 lobes in tlie hindwings, or tufts on the posterior legs. There is 

 an extensive array of further generic synonyms, which need not 

 be quoted here.
