Noctuidae 
(16) Noctua lubricans Guenee, Plate XXII, Fig. 8, $ . (The 
Slippery Dart.) 
Syn. associans Walker; illapsa Walker; beata Grote. 
A very common species, universally distributed throughout 
the United States. 
Genus PRONOCTUA Smith 
Only one species of this genus, named typica by Prof. 
J. B. Smith, is known. It is 
found in Colorado and Wyo¬ 
ming. Through the kindness 
of Dr. Dyar a drawing of the 
type was made for me at the 
United States National Museum 
and it is reproduced in the an¬ 
nexed cut (Fig. 104). 
Genus CHORIZAGROTIS Smith 
Eight species are attributed to this genus by Dyar in his 
recent Catalogue of the moths of the United States. We figure 
three of them. 
(1) Chorizagrotis introferens Grote, Plate XXII, Fig. 15, ? . 
(The Interfering Dart.) 
This insect is not scarce in Texas and Colorado, and thence 
ranges westward to California. 
(2) Chorizagrotis inconcinna Harvey, Plate XXII, Fig. 22, $ . 
(The Inelegant Dart.) 
An obscurely colored species occuring in the southwestern 
States. 
(3) Chorizagrotis balanitis Grote, Plate XXII, Fig. 17, $. 
(The Acorn Dart.) 
The range of this insect is from Colorado to British Columbia. 
Genus RHIZAGROTIS Smith 
About a dozen species have been assigned to this genus by 
recent writers. We figure one of them, to which Prof. 
J. B. Smith has applied the name proclivis. It is represented 
by a female specimen on Plate XXII, Fig. 16. The insect occurs 
in Arizona and northern Mexico.
