Noctuidse 

 Genus PLUSIA Hubner 



Three of the four species attributed to the genus as found in 

 America are represented upon our plate. 



(1) Plusia aerea Hubner, Plate XXVIII, Fig. 16, $ , 



The moth ranges from Nova Scotia to Florida and westward 

 to Texas and the region of the Rocky Mountains. 



(2) Plusia seroides Grote, Plate XX VIII, Fig. 17, $ . 



The distribution of this species is almost identical with that 

 of Plusia cerea. The larva feeds on various species of Spiraea. 



(3) Plusia balluca Geyer, Plate XXVIII, Fig. 22, ? . 



The species is not uncommon in the northern Atlantic States. 



Genus EUCHALCIA Hubner 



(1) Euchalcia contexta Grote, Plate XXVIII, Fig. 23, $ . 

 The species is found from Maine to Wisconsin, and occasion- 

 ally as far south as the mountains of central Pennsylvania. 



(2) Euchalcia putnami Grote, Plate XXVIII, Fig. 1 5, $ . 

 Dr. Dyar with questionable correctness treats this species as 



a form of the European festucce Linnaeus. There is no doubt of 

 the distinctness of the two. 



(3) Euchalcia venusta Walker, Plate XXVIII, Fig. 21, ?. 

 Syn. striatella Grote. 



The range of this species is from Nova Scotia and Canada 

 southward to the mountains of West Virginia. 



Genus EOSPHOROPTERYX Dyar 



(i) Eosphoropteryx thyatiroides Guenee, Plate XXVIII, 

 Fig. 1 8, $. 



This lovely moth is still very rare in collections. It ranges 

 from New England and Canada to the mountains of Virginia and 

 westward into the Valley of the Mississippi. 



Genus AUTOGRAPHA Hubner 



This is a large assemblage of species, about fifty being recog- 

 nized as occurring in the United States. Of this number we are 

 only able to figure about one third.
