OF WASHINGTON. 101 



being well relieved, the pale lines themselves scarcely distinguishable 

 from the ground color. Hind wing with two approximated dark lines. 

 Expanse, 27 mm. 



Two females, Glenwood Springs, Colorado, July 16-23 

 (Wm. Barnes) ; Clear Creek, Col., July 18, 1904 (E. J. Oslar). 



Type. No. 11928, U. S. National Museum. 



Near to binodulalis, but distinguished by the dark lines on 

 both wings. 



Herculia himonialis Zeller. 



I think this is not more than a variety of olinalis Guen. ; the 

 position of the lines on the hind wing seems to vary. 



My specimens are mostly from Texas and Colorado, though 

 some from the Atlantic Coast region agree very well. 



Herculia olinalis Guenee. 



Common in the Atlantic Coast region from Rhode Island 

 to Texas, westward to the Mississippi valley. I have a speci- 

 men from Las Vegas Hot Springs, New Mexico (H. S. 

 Barber) that seems referable here rather than to himonialis, 

 although somewhat intermediate in the position of the lines. 



Genus OMPHALOCERA Lederer. 



Omphalocera cariosa Lederer. 



I have specimens from Maryland, North Carolina, and 

 Alabama, the larvae on pawpaw ; the range probably extends 

 throughout the Mississippi Valley. The larva is black with 

 many white dots, a broad dull red dorsal and lateral stripe, the 

 former expanded on the centers of the segments. 



Omphalocera dentosa Grote. 



New Haven, Conn. (A. H. Verrill) ; Plummers Island, Mary- 

 land, June 6, 1902 (H. S. Barber) ; Ames, Iowa, June 6, 1896 

 (C. P. Gillette) ; Black Jack Springs, Texas (Wm. Barnes) ; 

 Dallas, Texas, May 31, 1896 (Dept. Agr. no. 6351), larvae on 

 Berberis. I have also a female from Durango, Colorado, that 

 is less vinous in tone and more darkly colored, perhaps a dis- 

 tinct species, but with the present material I do not venture to 

 separate it. 



Larvae received from Mr. A. H. Verrill, which I think be- 

 long to this species, are black with many white dots, without 

 the red lines of cariosa. 



Genus USCODYS. n. gen. 



Median vein of the hind wings weakly pectinate on the upper side; 

 maxillary palpi broadly triangularly scaled; labial palpi long, porrect,
