By Dr. Staudinger aqiiilina is considered as a var. of tritici, and some 

 others think that it is a doubtful species. Mr Doubleday, however, is of 

 opinion that it is a good species, forming one of a very puzzling group of 

 Agrotes, of which tritici may be considered the type. From that species it 

 may be distinguished by its comparatively longer wings, usually larger size, 

 and paler and more ochreous colour, especially of the subcostal line, which 

 in tritici is of usually a whitish tint. In this group we find really good 

 species, separated from each other by such slight (but constant) distinctions 

 that would scarcely serve to characterise varieties in some other groups.
