Habitat. — Canada; Eastern, Middle, and Central States, to Ne-

A well-marked form, not to be confounded with any in the same 

 group. Color characters have led to its reference to Orthosiid genera, 

 but it seems more properly referable here. Bodgei, of which I have 

 seen the type, is a pale variety of this species. 



Specimens in the Museum series are : From Long Island, Xew York, 

 June 21 (J. B. S.); Albany, New York, June 22-26 (INIeske) ; Adiron- 

 dack Mountains, New York (J. B. S.) ; Maine ; Iowa (C. V. K.). 



Group QUADRANNULATA. 



This group is best characterized in the description of the single 

 species belonging to it. 



Mamestra quadrannulata Morr. 

 1875. Morr., Proc. Acad. Nat. Sci., 1875, 430; Mamestra. 



Sordid, rather dark brownish fuscous, pale along the costal region 

 and internal margin. The median lines are obsolete. S. t. line con- 

 sisting of a series of small white dots. A dusky terminal line, inter- 

 rupted by white scales. A distinct black basal line extending nearly 

 to the middle of the wing, and looped at the end to form the small 

 claviform. Ordinary spots small, subequal in shape and size, rounded,
