three large irregularly shaped blotches on the inner margin, and a some- 
what lunate one in the apex, fuscous; costa spotted with fuscous ; sub- 
costal vein and one in the middle of the wing yellow, all the others 
fuscous, dotted with white ; posterior wings marked in a similar man- 
ner, but less distinctly, and the apical margin is very slightly excised.

Reddish brown, slightly hairy; antenne pale yellow; eyes black; 
palpi fuscous; thorax blackish fuscous at the sides; legs pale yellow, 
knees and tarsi fuscescent: anterior wings broader than in the last 
species, apical margin obliquely truncated, very slightly excised, hyaline, 
with a brownish tinge most manifest at the pterostigma, and along the 
dorsal margin a few scattered fuscous dots, and the apical and dorsal 
margins are spotted with fuscous, veins regularly pointed with fuscous ; 
posterior wings with no black dots, otherwise similar to the anterior. 
These two pretty species differ from the European O. Chrysops in 
the much finer reticulation of the wings, and the shape of these 
latter ; but the differences are so slight that I do not think it would 
be right to separate them generically at present.
