748 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



already sixteen from Australia; but at present none are known 

 from any other region. Doubtless, however, it will be found to 

 occur through Southern Asia and the Malay Archipelago. In 

 America it seems to be probably really absent; New Zealand has 

 also failed to produce this or any nearly allied genus. The Austra- 

 lian species are all more nearly allied together than to the European. 

 Very few of the larvae of the European species are known ; 

 these do not seem to present any peculiarity of habit. I have not 

 met with any of the Australian, but it is very probable that some 

 at least feed on grass.
