these Islands, but no doubt is thrown on the authenticity of 

 the specimen. The locality has long been destroyed, but

8. S. perlepidana, Haw. — Expanse I inch (12 mm.). 

 Fore wings rather pointed ; olive-brown, with a round olive- 

 black dorsal spot, edged by a shining white curved streak. 

 Remainder of wing much streaked with shining white. 



AntennjB black ; palpi and face pale brown ; head and 

 thorax dull brown ; abdomen black-brown. Fore wings

On the wing from the end of April till June. 



Larva apparently undescribed. Kaltenbach saj^s that it
