ANNETTE F. BRAUN. 337 



dorsal streak ; the space between the streaks and about tlie apical portion of the 

 wing is slightly shaded with rust-brown, and the apex is profusely sprinkled 

 with blackish scales mixed with some white ones ; a slender blackish line runs 

 around the extreme apex at the base of the pale cilia, which have a pale rust- 

 brown line running through their middle. Alar ex])anse 6 mm. 



"Hindwings and cilia grayish. Abdomen grayish. Legs whitish, unspotted."' 



Lord Wakinghiuii described the species from a specimen from 

 New York in the Beutentniiller collection. 



Liithocolletis piatanoicliella Brann. 

 Plate XXIII, Fig. 23. 

 Lithocolh'tis plaUmoidiella Braun, Ent. News, xix, 106, 1908. 



Antennae whitish, banded with brown above. Palpi shining white. Face 

 shining white, with a slight golden lustre. Tuft golden. 



Thorax and forewings deep shining ocherous. Extreme edge of the costa 

 towards the base black. The first costal streak at the basal fourth s'hort. oblique 

 and outwardly dark margined. The second costal streak at the middle of the 

 wing length is also oblique, and its apex meets that of the longer corresponding 

 dorsal streak, which begins at the middle of the dorsal margin, somewhat nearer 

 the base than the costal streak. There is thus formed an interrupted, augulated 

 white fascia, of which the external dark dusting is continuous, and is prolonged 

 backward to the space between the third costal and the second dorsal streaks. 

 These latter streaks are placed opposite to each other, the costal at the apical 

 third, the dorsal at the tornus, and both are dark margined behind. Fourth cos- 

 tal streak somewhat oblique, pointing forwards, and dark margined behind by a 

 few black scales. Apical portion white, dusted with black scales. This dusted 

 portion forms an almost rectangular area. At the base of the costal cilia, but 

 not extending through them, and anterior to the dusted apex, is a small white 

 streak. Marginal line in the cilia brown. Cilia ocherous around the apex, be- 

 coming gray towards the tornus. Alar expanse 6.5-8 mm. 



Hindwings gray. Cilia gray, tinged with reddish. Abdomen gray aliove. 

 shining silvery ocherous beneath. Anal tuft ocherous. Front legs daik brown 

 above, with a narrow white stripe beneath. Tarsi white at their bases. Middle 

 aud hind legs whitish ocherous, their tarsi tijjped with black. 



I have bred this species at Cincinnati, Ohio, from blotch mines 

 on the upper surface of leaves of several species of oak, viz. : Querciis 

 alba L., Quercus macrocarpa Michx., Quercus j)lutanoides (Lam.). 

 The larva is of the flat type, and wlien mature spins an oval flat 

 cocoon. The imagoes appear in August. The larvse of the fall 

 brood hibernate in silken lined chambers. There is a specimen in 

 the U. S. Nat. Mus. from New York (Beutenmiiller collection). 



This species superficially resembles L. betlmnella Cham., from 

 which it can be distinguished by the aljsence of the dorsal streak at 

 the basal fourth, and by the presence of two costal streaks beyond 

 the fascia, there being but one such streak in L. bethunella.
