 This very fine new species is allied to O. cacica, Bdv., H.-Sch., but has the fore wings 

 rather less triangular, and they do not possess the small oblong cell seen in other species, 

 formed by the connexion of the second and third branches of the subcostal vein by a 

 small transverse veinlet (see PI. XXVIII. fig. 9).
