more oblique, pointing outwards from the dorsal 

 margin. The costal cilia on the anterior lobe 

 are white up to the apex, as are also those in the 

 sinus on the outer margin of the falcate second 

 lobe and along the dorsal margin, except imme- 

 diately preceding the anal angle, where they are 

 broadly and distinctly fuscous. There is also a 

 fuscous spot in the cilia of the dorsal margin just 

 before the first pale transverse band. Within 

 tlie fissure the cilia are brownish fuscous. 



The two anterior lobes of the hind wings are reddish 

 brown, redder than in 0. pUoseUw, ericetoriim, 

 or periscelidactyhis ; the third lobe paler, some- 

 times touched with whitish, having a few blackish 

 scales along its hinder margin, and a triangular- 

 shaped patch of blackish scales immediately 

 preceding the whitish apex, with a few similar 

 scales on the costal margin- above them. The 

 patch is of a different shape to that of 0. tenui- 

 (lactylus, which is squarer, forming as it were a 

 more even spatule. Moreover the lobe itself is 

 less distinctly marked with white than in that 

 species. 



The abdomen is yellowish white, at the base reddish 

 brown, indistinctly marked with whitish scales 

 and lines beyond, but not so conspicuously 

 marked as in tenuidactylus. 



The legs are white, beautifully barred with dark 

 brown. The spurs wiiite, marked with a brown 

 line along their inner surface.
