Noctuidss 



The species is found in Colorado, and probably has a wide 

 range in the Rocky Mountains. 



(16) Autographa ampla Walker, Plate XXVIII, Fig. 31, $. 

 This fine species is northern in its range, but extends its 



habitat southward along the ranges of the great mountains of the 

 west 



(17) Autographa basigera Walker, Plate XXVIII, Fig. 26, $ . 



Syn. laticlavia Morrison. 



The insect occurs in the Appalachian subregion. 



(18) Autographa simplex Guenee, Plate XXVIII, Fig. 37, $. 

 This is one of the very commonest species of the genus, 



which is apparently universally distributed throughout our 

 country. 



Genus SYNGRAPHA Hubner 



This genus is composed of species which are subpolar in 

 their habitat. Of the four species which are reckoned as belong- 

 ing to the fauna of North America, we illustrate two. 



(1) Syngrapha hochenwarthi Hochenwarth, Plate XXVIII, 

 Fig. 41. 3 . 



Syn. divergens Fabricius. 



Found everywhere in Arctic America. The specimen figured 

 was taken in Labrador. 



(2) Syngrapha devergens Hubner, Plate XXVIII, Fig. 40, ? . 



Syn. alticola Walker. 



The species is found in Labrador, and has been reported from 

 the high mountains of Colorado. It will probably be found to 

 have a wide range. 



Genus ABROSTOLA Ochsenheimer 



We give representations of both the species which occur in 

 our fauna. 



(1) Abrostola urentis Guenee, Plate XXVIII, Fig. 42, $. 

 The insect, which is by no means common, is found in the 



Appalachian subregion. 



(2) Abrostola ovalis Guenee, Plate XXVIII, Fig. J.3, & . 

 The range of this insect is the same as that of the last 



mentioned.
