296 AMERICAN MICRO-LEPIDOPTERA. 



two very narrow, slightly curved streaks. At the apex is a black dot or a streak, 

 bordered with white scales toward the base. Cilia light, darker toward the tor- 

 nus, with a blackish marginal line around the apex. 



Hindwings dark gray. Cilia somewhat lighter. 



The last three light costal streaks are visible on the dark brownish underside 

 of the forewings. 



The larvae are abundant in October and November on several species of Salix. 

 The mine is on the underside between the veins. It is elongate-oval and some- 

 what wrinkled. The imagoes emerged in April and May. 



The above is a translation of Frey's description of L. scudderella. 

 The second costal streak is placed rather beyond the middle than at 

 the middle. In some specimens, there is also a third dorsal streak 

 above the tornus. The apical black marking, when a streak, is 

 often margined not only before with white scales, but also above for 

 its whole length. Alar expanse 7.5-9 mm. 



I have flown specimens taken at Cincinnati, Ohio, which are oi' a 

 lighter and more grayish color than specimens bred by Mr. W. D. 

 Kearfott on willow, Essex County Park, N. J.

"Antennae whitish, faintly barred above with brown. Palpi white. Face 

 white, frontal tuft saffron, mixed with whitish. Thorax golden safiYon, with a 

 few white scales. 



"Forewings golden saffron with a white niedio-basal streak, somewhat expand- 

 ing outwards on the fold and reaching to one-third the length of the wing above 

 it, this is dark margined on its upper edge; beyond it are four costal and four 

 dorsal silvery white streaks; the first dorsal commences beneath the point of the 

 basal streak and extends obliquely outward to the middle of the wing, it is dark 

 margined internally and around its apex ; the costal streak above it is short, 

 rather square, and also internally dark margined ; the second costal streak 

 scarcely longer than the first, is a little oblique and also inwardly dark margined ; 

 beyond this are two more narrow costal streaks, the first curved outwards, and 

 dark margined internally, the second pointing inwards from above the apex, 

 with a few black scales at the extremity ; the second dorsal streak is triangular, 

 dark margined internally and around the apex, commencing somewhat further 

 from the base than the second costal streak, its point lies between the second 

 and third ; the last two of the four dorsal streaks are very slender, and pointing 

 inward, with a few black scales at their ends, where they reach the points of the 

 costal streaks above them ; a black elongate spot lies at the apex, separated from 

 the dark apical line which lies at the base of the golden gray apical cilia. 



"Hindwings and cilia gray, with a faint golden sheen. Abdomen gray, and 

 tuft jialer. Hind tarsi whitish gray, unspotted. Alar expanse, 9-10 mm."
