644 REVISION OF AUSTRALIAN LEPIDOPTERA, IV., 



cilia ochreous-whitish with a basal series of dark fuscous dots 

 opposite veins. Hindwings with termen rounded; in ^ dorsal 

 area beneath densely clothed with hair}'^ scales; colour and 

 markings as forewings. 



Type in Coll. Turner.

 Brisbane; in December and February.

Face smooth. Palpi short, slender, porrect, or slightly ascend- 

 ing. Antennae in g ciliated. Posterior tibite and tarsi in ^ 

 slender and rudimentary, or more or less dilated and distorted; 

 posterior tibije in O without middle spurs. Forewings with 7, 8, 

 9, 10 stalked, 11 anastomosing with their common stalk, forming 

 a single areole. Hindwings with vein 5 from middle of cell, 6 

 and 7 stalked. 



A large and cosmopolitan genus. In the Australian species 6 

 and 7 of hindwings are always stalked; according to Meyrick 

 they are rarely separate in exotic species. The Australian 

 species may be readily separated into two sections according to 

 the structure of the hindlegs of the ^, but it must not be sup- 

 posed that these would form tenable genera. In the following 

 table, which is based on characters only found in the ^ — and I 

 am convinced that this is the only scientific method of studying 

 this genus — the following species are unavoidably omitted : £J. 

 alopecodes M.eyr., iodesma Meyr., plumboscriptai'ia Christ., jwly- 

 gramma Low., stenozona Low.
