22 AMERICAN LEPIDOPTERA. 



1. C. argyrosplendella n. sp. (Plate II, figs. 13, 13a, 136.) — 

 Palpi white, dusted externally with fuscous, slender, third joint nearly 

 as long as the preceding one, pointed. Head white, with pearly 

 lustre. Antennas pale grayish-fuscous, basal joint white, instead of 

 pecten, a large conchyloidal shield of close set white scales, longer 

 than width of joint ; stalk grayish-fuscous paler towards the base, not 

 excised above in the male, shortly pubescent beneath. Head and 

 thorax white, with pearly lustre, lightly flecked with a few pale fus- 

 cous scales, the latter more in evidence on the thoracic disk. Fore- 

 wings elongate, widened outwardly, costa slightly convex at the base, 

 thence nearly straight and not strongly depressed towards the apex ; 

 pale yellowish white with strong lustre, extreme costal margin dark 

 brown, lightly suffused with pale reddish-brown in apical portion ; 

 underside fuscous. Hindwings nearly 1, rather strongly narrowed 

 towards the acutely pointed apex, costa refuse in outer three-fifths ; 

 pale grayish-white, lustrous ; cilia a trifle over 1 ; underside white. 

 Abdomen grayish-white, somewhat fuscous towards the base, with a 

 certain lustre. Anal bush yellowish-white. Underside of body and 

 legs, silvery white, with lustre, the anterior legs somewhat suffused 

 with fuscous, tarsi likewise ; brush of hind tibia white, Expanse 10.5- 

 12.0 mm., 0.43-0.48 inch. 



Hab. — Pennsylvania (Hazleton, July 4, 1906); La. (Vo- 

 wells Mill, April, 1902); Fla. (Hastings, May 16, 1902). 



Differs from dianella by its narrower wings, acutely 

 pointed hindwings, costa of forewings nearly straight, gener- 

 ally paler color and smaller size. Three specimens in my 

 collection, from as many localities, would seem to indicate a 

 rather wide distribution of this interesting addition to our 

 fauna. 



2. C. dianella n. sp. — Palpi slender, reaching to antennal inser- 

 tion, sordid white, dusted externally with fuscous, the third joint three- 

 fourths the length of the second. Head and thorax creamy white, 

 the former very smooth scaled with a greenish lustre, the latter lightly 

 dusted with pale ochreous-fuscous with some lustre. Antennas slender, 

 simple ; slightly pubescent beneath and not excised above the base in 

 the male ; basal joint of moderate length, slightly curved, nearly twice 

 as long as wide, creamy white, conchoidal shield of long, close set 

 scales, concolorous with basal joint. Forewings relatively wide, costa 

 slightly convex from the base, sharply pointed, creamy yellow, thinly 

 overlaid with pale ochreous-fuscous except for three-fourths of the 

 costal margin, which is thus left paler; no markings; cilia pale 

 ochreous-yellow. Hindwings as wide as the forewings, rather ob- 

 tusely pointed, costa not refuse, except a slight sinuosity beyond inser-
