irrorated witb grey, especially towards the apex ; posterior wings 

 hyaline. 



Habitat, Australia. In the British Museum. 



Closely allied to the preceding ; differs in its slightly larger 

 size, more hoary anterior wings, and in the posterior wings want- 

 ing the cupreous iridescence. 



These two species, with L. magnus, Walker, and L. oppositus. 

 Walker, from Tasmania, form a group apparently peculiar to Aus- 

 tralia and New Zealand.
