Liithocolletis fletcherella sp. nov. 

 Plate XXIII, Fig. 24. 



Antennse whitish, banded above with brown. Face white; palpi white inter- 

 nally, dark externally. Tuft ocherous, whitish in the middle. 



Thorax and forewinprs reddish ocherous. Four white costal and three white 

 dorsal streaks, all margined with dark brown externally. First costal and dor- 

 sal streaks oblique, the costal at the basal third, the dorsal a little nearer the 

 base, aud extending slightly beyond the fold ; its pointed apex is directed toward 

 that of the first costal streak. Second pair of streaks at the middle almost 

 parallel to the first pair, meeting to form a more or less interrupted angulated 

 fascia, of which the dark margin is continuous. Third pair of streaks at the apical 

 third, perpendicular and almost meeting in the middle of the wing. Fourth 

 costal streak curved, almost inclosing the more or less dusted apex. In the male, 

 on the middle of the wing, half way between the third pair of streaks and the 

 fourth costal streak, is a white spot, with a few dark scales behind it. Cilia 

 ocherous. Expanse 8.5-9 mm. 



Hindwings and cilia grayish ocherous. Abdomen ocherous gray, tuft ocher- 

 ous. Legs ocherous, hind tarsi pure white. 



Described from specimens sent to me by Dr. Fletcher from the 

 Central Experimental Farm, Ottawa, Canada, where they were bred 

 from white oak by Mr. Arthur Gibson. 



liitltocolletis arcuella Brauu. 

 Plate XXIV, Fig. 1. 

 Lithocolletis arcuella Brauu, Ent. News, xix, 107, 1908. 



Antennae whitish, annulate with brown above, tips blackish. Palpi silvery 

 white. Face silvery white, slightly tinged with golden. Tuft yellow, mixed 

 with orange at the sides. 



Thorax and forewing shining reddish orange, with glistening white markings. 

 There are three costal and three dorsal white spots, the second pair uniting to 

 form a fascia; all black margined externally. The first costal spot at the basal 

 third is short and broad, its dark margin passing around its apex almost encloses 

 it. The first dorsal, almost square, begins nearer the base than the first costal, 

 and extends half way across the wing. A bioad white angulated fascia at about 

 the middle, black margined externally, and on the costa internally. Third cos- 

 tal streak strongly arcuate and opposite the more triangular dorsal streak ; the 

 external dusting densest immediately behind their apices. Apical portion 

 densely dusted with blackish brown scales, aud bordered internally by an indis- 

 tinct outwardly concave streak of silvery scales. Marginal line in cilia brown- 

 ish. Cilia golden, becoming grayish toward the tornus. Alar expanse 10 mm. 



Hindwings bronzy gray, cilia gray. Abdomen bronzy gray above, silvery 

 beneath. Anal tuft reddish. Legs, except the first pair, ocherous; tarsi whitish 

 and unspotted. First pair striped with dark gray, tarsi banded with gray. 



One specimen taken at Mountain Lake, Giles County, Virginia, 

 June 20, 1907. A very large and distinctly marked species, be- 

 longing to the same group as L. bethunella Cham.
