Hysterosia birdana, new species. 



Labial palpi blackish brown. Head dark brown intermixed with ochreous 

 Thorax dark purplish brown with a posterior tuft. Fore wings dark violet 

 brown with still darker purplish brown markings as follows: a costal spot at 

 base; another before the middle of the wing, which emits a narrojv inwardly 

 oblique fascia, which gradually widens until it reaches the dorsal edge at 

 basal third. A round dark spot within the dorsal edge at apical third and the 

 entire tip of the wing limited inwardly by a straight line running from tornus 

 to apical third of costal edge. At the end of the cell is a small round black 

 dot. Hind wings above light ochreous fuscous with the ornamentation of 

 the under side faintly showing through; under side whitish with numerous, 

 undulating, transverse, dark fuscous lines running across the wing. Ab- 

 domen ochreous fuscous. Legs ochreous, shaded externally with black. 



Alar expanse: 27 mm. 



Habitat: Rye, New York (H. Bird). 



Type: U. S. N. M., No. 10240. ' 



Food plant: Helianthus. 



Bred by Mr. H. Bird from larvae boring in the roots of Helian- 

 thus, occurring with those of Papaipema nelita Strecker. 



This fine species, which I take pleasure in naming in honor of 

 the discoverer, is by far the largest and darkest of the genus, and 

 can not be mistaken for any of the other described species, 

 though partaking in the general common scheme of markings. 



Hysterosia modestana, new species. 



Labial palpi dark fuscous with inner surfaces ochreous. Face, head and 

 thorax dark fuscous; thorax smooth. Fore wings uniformly dark fuscous 

 with a strong silky lustre; at the end of the cell outside of the usual small 

 black dot is a small transverse blackish spot and between this and the apex 

 is another larger blackish spot. Hind wings dark ochreous fuscous above; 

 under side whitish fuscous checkered with dark fuscous transverse striation. 

 Abdomen, dark fuscous. Anterior legs black with ochreous annulations on 

 tarsal joints; posterior legs ochreous, mottled with black.
