Lithocolletis macrocarpella Frey and Boll. 



(Plate XXIII, Fig. 11.) 



Lithocolletis macrocarpella Frey and Boll, Stett. ent. Zeit, xxxix, 261, 1878. 

 Walsingham, Ins. Life, ii, 78, 1889. Dyar, Bull. 52, U. S. Nat. Mus., 

 1902, No. 6289. 



Face, palpi and underside of the antennae white, antennae above annulate with 

 brown ; tuft white, mixed with brown and saffron scales. 



Thorax brownish saffron, with its apex and two longitudinal stripes white. 

 Sometimes almost the entire thorax is white. Forewings brownish saffron, very 

 feebly shining. A broad curved basal streak from the inner margin to the fold 

 is densely dusted behind with blackish scales. Two white fasciae angulated near 

 the costa, one at the basal third, the other at the middle of the wing length ; the 

 dorsal arm of each slightly curved. Each fascia is internally margined by a few 

 black scales near the costal and the dorsal margins. On the outer side the costal 

 arm of each has a few black scales near the costa; the dorsal arm is densely 

 dusted with blackish scales, which are produced backward at the angle. A 

 white costal streak at two-thirds is dusted with blackish scales. Opposite it is 

 an oblique curved dorsal streak, dusted behind with blackish scales, running 

 into the dusted apical portion. Before the apex is a white costal streak with a 

 few black scales before it on the costa. Apical part of the wing dusted with 

 black on a white ground. Hinder marginal line in the cilia brownish, with a 

 few blackish scales intermixed. Cilia around the apex of the wing color, gray- 

 ish toward the tornus. In the cilia, extending outwards from the apex, is a 

 small pencil of dark brown scales. Expanse 8.5-9 mm. 



Hindwings brownish gray, with somewhat lighter cilia. Abdomen in the 

 male dark gray, in the female lighter, somewhat ocherous. Anal tuft ocherous 

 brown. Legs and tarsi whitish, spotted with dark brown. 



This species was originally described by Frey and Boll from 

 specimens from mines on the upperside of leaves of Quercus macro- 

 earpa Michx. in Texas. I have a series of specimens bred by Mr. 

 W. D. Kearfott from blotch mines on the upperside of leaves of 

 chestnut, Montclair, N. J. The density of the black dusting varies 

 somewhat, and in one specimen the basal streak is confluent with 

 the dorsal arm of the first fascia. 



Very close to L. cincinnatiella Chambers, but distinguished from 

 it by the larger size, darker and less shining ground color of the 

 forewings; the more oblique and slightly curved dorsal streaks; and 

 the tuft of dark brown scales in the apical cilia, which is wanting in 

 cincinnatiella. 



The mine of macrocarpella also differs from that of cincinnatiella, 

 being of the usual upperside blotch type and containing but a single 

 larva.
