AMERICAN LEPIDOPTKRA. 41 



Only one species known : 



C vesaliella Cham.— Pi. VI, fig. 5. — Dyar's List, p. 573, No. 6535.— Head 

 sordid yellowish white, intermixed on the vertex with brown. Maxillary and 

 labial palpi yellowish white, second joint of latter externally and a spot on the 

 terminal, as well as setse, dark brown. Antennae yellowish white, annulate with 

 brown. Thorax brown, mixed with whitish in posterior two-thirds. Forewings 

 grayish fuscous; extreme base, costa and adjacent part of wing dark brown, just 

 beyond the middle the brown expands into a large spot, extending fully one-half 

 across the wing, before this spot the brown costal margin is interrupted by about 

 three or four, and beyond it by two white, somewhat oblique stria;; a dark spot 

 near base of dorsal margin and obliquely above two more, s spot in middle of 

 dorsal margin, and between it and the large costal spot is another smaller spot; 

 dorsal cilia whitish, costo-apical dark brown, containing three white spots. Hind- 

 wings grayish fuscous; cilia a shade paler, with a faint darker line near the base. 

 Abdomen fuscous, darker posteriorly, anal brush pale brown. Underside of 

 wings and abdomen brownish fuscous. Legs greyish fuscous. 



Exp. 8.5-11.0 mm.; 0.34-0.44 inch. 



Hub. — Kentucky, Pennsylvania, New Jersey, New York, Florida, 

 Louisiana. 



Specimens in my collection from the localities named, except 

 Kentucky. There is some variation in the relative predominence of 

 the brown and pale coloring of the forewings. In a specimen from 

 Florida, the spots on the dorsal margin become bands, and there is 

 a suffusion of golden brown in the apical rjart of the wing.

Type acerijoliella. 



Head rough, labial palpi rather short, drooping; second joint 

 with a few setse. Maxillary palpi plicate. Antenna? stout, some 

 what flattened, joints closely set with scarcely perceptible denticula- 

 tions, glabrous in both sexes, basal joint with pecten. Forewings 

 elliptical, broad, equally narrowed from both margins towards the 

 apex. 11 veins, veins 2, 3 and 4 parallel and at almost right angle 

 to the dorsal margin, 5 absent, \ b furcate. Hindwings as wide as 

 forewings, subtrapezoidal, scales filiform; 8 veins, 5 6 short stem- 

 med, \ b furcate. Cilia under 1. Hind tibia rough haired. 



In Mr. Busck's opinion it is vein 4 of forewing winch is wanting, 

 in this I must beg to differ from him. The furcation of vein V> of 

 hindwing is anomolous.
