Two males, a female, and a dam- 

 aged specimen [half of abdomen 

 lost], probably a female, taken on 

 Lord Howe Island. In coloura- 

 tion, this species closely resembles 

 M. roseistiyina Esb.-Pet. It can at 

 once be distinguished from that 



species by its much narrower and more pointed wings, by the 

 two series of connecting cross-veins in the costal area of the fore- 

 wing, and by the less definite closure of the "disc." In this last 

 character, it approaches the genus Osmylops. 



There is also, in the collection, a single larva of this species,
