Male. Body slender. Proboscis very short. Palpi short, 

 stout, very hairy; third joint very small. Antennae very deeply pec- 

 tinated. Legs slender; hind tibiae with two rather short apical 

 spurs, or with four moderately long spurs. Wings broad. Fore 

 wings with the first, second and third inferior veins near together; 

 fourth remote from them. Hind wings extending beyond the

O. leucostigma and O. bicolor have four spurs on the hind 

 tibiae, and ought perhaps to be separated from this genus.
