282 AMERICAN MICRO-LEPIDOPTERA. 



suffused with golden beneath the fold. From the middle to the tip pale golden, 

 with four costal silvery streaks, dark margined internally and two dorsal silvery 

 streaks, the first opposite the second costal streak and both dark margined inter- 

 nally; the first costal streak not decidedly dark margined. Apical spot black. 

 Hinder marginal line in the cilia dark brown ; cilia pale gray. Hindwings shin- 

 ing bluish gray ; cilia gray. 



"The larva mines the under side of the maple leaf, Acer saccharinum, in July, 

 September and October. The head is pale brown ; body pale green, colored 

 darker by the ingesta. " Frass" collected into a ball within the mine. The 

 pupa is suspended in a web of silk within the mine." 



The above is Clemens' description. As noticed by Stairiton, the 

 statement, " the first costal streak not decidedly dark margined," is 

 an error. This streak is decidedly dark margined, as is also the 

 first dorsal. The extent of the wing suffused with golden also 

 varies ; in some specimens being merely a golden line extending 

 from the golden apical half of the wing along the fold toward the 

 base ; in others the entire basal half of the wing below the fold is 

 golden. Expanse 6.5 mm.

Antennae white, dark brown at the apex. Face and palpi shining snow-white. 

 Tuft white, mixed with pale yellowish brown scales. 



Thorax shining white. Forewings pale golden brown. There is a broad white 

 basal streak ending in a point at about two-fifths of the wing length and black 

 margined toward the costa. At the basal third is a very oblique costal streak, 

 with its internal black margin produced along the costa to the base. Opposite to 

 its apex is the apex of the larger first dorsal streak, which is continued as a 

 broad band along the dorsal margin to the base. Near the base it is confluent 

 with the basal streak, leaving only a narrow streak of the ground color between 

 its apex and the basal streak. The black margin at the apex of the first dorsal 

 streak extends along its upper edge toward the base for a greater or less distance. 

 In the apical half of the wing are three costal and one or two dorsal streaks. 

 Second costal and dorsal streaks opposite each other, sometimes meeting, and 

 their oblique dark internal margins often uniting in the middle of the wing. 

 Third and fourth costal streaks nearly perpendicular, the fourth sometimes un- 

 margined, the third opposite the third dorsal streak, which is often small or indi- 

 cated by its dark margin only. A black apical spot with a few silvery scales 

 before it. A dark marginal line in the cilia, which are pale golden around the 

 apex, with a gray streak below the fourth costal streak, shading to grayish white 

 toward the tornus. Expanse 6-7.5 mm.
