This common and widely-spread species may be distinguished by its 

 white front, which is more triangular than in Eudeilinia lierminiatn, and by 

 the white wings. It varies in sometimes not being tinged with brown on the 

 under side of the costa, both in examples from Maine and Texas. It is one 

 of the earliest of our Gcometrids.
