294 AMERICAN MICRO-LEPIDOPTERA. 



gined on both sides ; the corresponding dorsal streak is more prop- 

 erly called a spot, and is scarcely dark margined. The expanse is 

 6.5-8.2 mm. 



Lilhocolletis diaphaiiella Frey and Boll. 



Plate XXII, Fig. 1. 



Lithocolletis diaphanella Frey and Boll, Stett. ent. Zeit., xxxix, 265, 1878. Dyar, 

 Bull. 52, U. S. Nat. Mus., 1902, No. 6277. 



Head, face, palpi and tuft snow white. Antennae white, faintly annulate with 

 ochre-yellow; basal joint ochre-yellow. Tegulse snow white, thorax pale golden 

 yellow. Abdomen whitish gray; legs whitish, tarsi annulate with brown. 



Forewings pale golden brown, marks white. There is a broad basal streak 

 without any dark margining extending for more than two-fifths of the wing 

 length. It begins rather broad, and ends in a long point directed toward the 

 costa. Behind the middle of the wing there is a small, bent, very oblique costal 

 streak, faintly blackish margined toward the base. There is a similarly bent 

 but broader dorsal streak beginning nearer the base and pointing toward the first 

 costal streak. On the costa follow very small, faintly inwardly dark margined 

 streaks. A fourth one is indicated by a few white scales. At the hind angle is 

 an inwardly blackish margined white dorsal triangle. It apex extends between 

 the second and third costal streaks. From this, a line of blackish scales extends 

 toward the terrnen. Cilia whitish, with a blackish basal line. The latter only 

 extends around the apical part of the wing. [Expanse 6 mm.] 



Hindwings light, yellowish gray, cilia whitish. 



This species, the habitat of. which is given as Texas, is an under- 

 side miner on scrub oak. A peculiar characteristic of the mine, as 

 noted by Frey and Boll, is its transparent appearance, when mature, 

 allowing the pupa to be plainly visible through the epidermis. 



The description is a translation of the original. 



There is a specimen of this species from Texas in the U. S. Nat.

LithocolleUs mimitella Frey and Boll. 



Lithocolletis minutella Frey and Boll, Stett. ent. Zeit., xxxix, 263, 1878. Dyar, 

 Bull. 52, U. S. Nat. Mus., 1902, No. 6276. 



Head and tuft pale golden brown, the latter mixed with white. Face and 

 palpi whitish ; antennae whitish, obscurely annulate with brown. 



Thorax pale golden brown, tegulse bordered with whitish, abdomen gray, with 

 a yellowish white tuft. Legs whitish, all the tarsi spotted with black. 



The pale golden brown (approaching the color of L. faginella) faintly shining 

 forewings have peculiar white markings. There is a short narrow basal streak 

 dark margined toward the costa, ending just before the two-fifths of the wing 

 length. The first costal streak beginning at two-fifths is placed very obliquely, 

 is dark margined toward the base, sharply bent at an angle in the fold, and is 

 then prolonged as a very short spur toward the dorsum and base. Beginning 

 under the apex of the basal streak, and extending toward the costal streak, is a
