Noctuidae 
Genus PLUSIA Hubner 
Three of the four species attributed to the genus as found in 
America are represented upon our plate. 
(1) Plusia aerea Hiibner, 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 aeroides Grote, Plate XXVIII, Fig. 17, &. 
The distribution of this species is almost identical with that 
of Plusia cerea. The larva feeds on various species of Spircea. 
(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. 15, $ . 
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 
(1) Eosphoropteryx thyatiroides Guenee, Plate XXVIII, 
Fig. 18, $ . 
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.
