There is consiclerabL> doubt about the correctness of the above 

 synonymy. From Knight's figure in the American Museum it does 

 not seem that primariana can be the same as fulvifrontana^ and it 

 is also a question whether either is equivalent to septentrionana. 

 Until some one can examine the genitalia of Walkers' and Curtis* 

 types the synonymy may as well stand as it is. 



O. fulvifrontana has genitalia similar to those of inquietana, ex- 

 cept that the spining of cucullus fuses more completely with that at 

 th: apex of the extended sacculus, and that there is less of a break 

 between cucullus and extended sacculus than in the latter species. 

 The fore wing pattern reminds strongly of that of some specimens 

 of schulziana. Packard's species, however, lacks any sign of a round 

 white dot at end of cell; the basal patch is well marked, strongly 

 angulate outwardly; the median dark band narrow on costa, broad 

 on dorsum and fused with subtornal spot, and has only one project- 

 ing tooth and that from middle; the apical dark markings are 

 somewhat variable, being different in type and paratype and even 

 on the right and left fore wings of the type ; the dark markings are 

 a rick brown shaded with black, and the pale antemedian and post- 

 median areas a whitish ochreous. 



Besides the type and paratype at Cambridge there is a broken 

 and faded paratype (female without abdomen) in the Academy of 

 Natural Sciences at Philadelphia, and two small Labrador speci- 

 mens from the Fernald collection in the National Museum.
