BY E. MEYRICK. 563 



A development of Erechthias ; besides the eight Australian I 

 have also eight New Zealand species. The typical genus Erech- 

 thias, differing from Ereunetis (according to the present revised 

 definition) by the presence of all veins in the forewings, is confined 

 to New Zealand. Decadarchis, Meyr., cannot be maintained as a 

 distinct genus, and must be merged in Ereunetis.
