Lithocolletis betulivora Walsingham. 



Plate XXiV, Fig. 2. 



Lithocolletis betulivora Walsingham, Ins. Life, iii, 326, 1891. Dyar, Bull. 52, U. 

 S. Nat. Mus., 1902, No. 6328. 



"Antennae grayish above, white beneath. Palpi white. Head and face white, 

 crown tufted with reddish saffron. Thorax reddish saffron. 



" Forewings shining reddish saffron, no basal streak, a small costal spot at one- 

 fourth the wing length and a small dorsal spot nearer to the base dull white, a 

 slender fascia at the middle of the wing angulated outwardly near the costal 

 margin, has one or two black scales on its outer edge ; beyond this a small costal 

 streak and an opposite dorsal streak, both dull white, with a few blackish scales 

 on their outer edges. A group of black scales at the apex of the wing is preceded 

 on the costal and dorsal margins by dull white, not sufficiently conspicuous to 

 be called costal and dorsal streaks; cilia grayish, their bases tinged with saffron, 

 a slender blackish line along their middle, passing round the apex. 



"Hindwings dark gray; cilia gray. Abdomen gray, tinged with saffron pos- 

 teriorly. Hind legs whitish, with a very faint indication of darker scaling on 

 the penultimate tarsal joint. Expanse 7 mm." 



Lord Walsingham has thus described the species from a female 

 specimen bred from birch by Dr. Riley. 



The mine is a small, sometimes almost circular, blotch upon the 

 upper side of the leaf. 



There is a specimen of this species in the U. S. Nat. Mus. bred 

 from birch, but no locality is given. 



Lithocollelis eppelsheimii Frey and Boll. 



Lithocolletis eppelsheimii Frey and Boll, Stett. ent. Zeit, xxxix, 272, 1878. Dyar, 

 Bull. 52, U. S. Nat. Mus., 1902, No. 6325. 



Face and palpi snow-white; tuft saffron yellow. The antennae whitish gray, 

 annulate with brown, attain an unusual length. They fully equal the length of 

 the forewings. Thorax saffron ; legs whitish, with unspotted tarsi. Abdomen 

 dark gray, light underneath. 



The moderately shining forewings have a true saffron color. They show the 

 following shining silvery white markings; on the costa at one-third of the wing 

 length there is a rather small, obliquely placed costal streak, imperfectly mar- 

 gined toward the base with a few black scales. The corresponding dorsal streak 

 is short, blunt, not well developed, placed at the basal fourth of the wing length, 

 and is externally more strongly margined with blackish scales. Then follows, 

 about in'^the middle of the wing, an angulated, interrupted fascia, inwardly 

 blackish margined, and with a shorter costal and a longer dorsal arm. At three- 

 quarters of the wing length is a pair of streaks, the dorsal placed at the hind 

 angle. The trace of a last costal streak appears just before the apex. The black 

 dusting extends in considerable breadth from the above-mentioned pair of 

 streaks to the hind margin, either in the shape of a broad spot, or to the unaided 

 eye as a dot suddenly ending. Base of the cilia saffron, tips whitish gray. At 

 the hind angle they become entirely of a uniform light gray. 



Hindwings and cilia gray. The underside of the forewings dark ocherous gray.
