Noctuid^ 



(i6) 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 bv 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). Fig. lOA.—Pronoctua typica. 



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. 



(i) 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 XXll, Fig. 22, ? . 

 (The Inelegant Dart.) 



An obscurely colored species occuring in the southwestern 

 States. 



(3) Chorizagrotis balanitis Grote, Plate XXII, Fig. 17, 3 . 

 (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.
