ANNETTE F. BRAUN. 305 



Zoology, Cambridge, Mass. A number of specimens collected by 

 Mr. W. D. Kearfott, in Pike County, Penna., are identical with 

 the type. 



While very closely allied to ceriferella Clem., sexnotella may be 

 distinguished by its paler color, the pure white dorsal and costal 

 streaks, and by having its second dorsal streak opposite the space 

 between the second and third costal streaks. The internal margins 

 of the corresponding costal and dorsal streaks never unite in the 

 middle of the wing.

"Antennae dark brown above, white beneath. Front silvery white; tuft dark 

 brown. Forewings pale reddish saffron, with a golden hue, especially from the 

 middle to the base, with four silvery costal streaks, the first on the middle of the 

 costa, and all, except the lust, black margined toward the base, the third but 

 faintly, and the costa black from the base to the first costal streak. Three sil- 

 very dorsal streaks on the inner margin, the first two large and the third small, 

 the first black margined internally and around the tip behind, the second by a 

 line curved above. Apical spot small and black, with the scales behind it having 

 a bluish splendent lustre; hinder marginal line blackish; cilia dark grayish, 

 with a fulvous hue. Hind wings dark gray, cilia fulvous. 



"The larva may be found in the leaves of oaks in September and early in 

 October. It makes a small mine on the under surface, and the leaf is thrown 

 into a fold previously to pupation and the cuticles folded and corrugated. . The 

 pupa is contained in an ovoid cocoon, within the mine, composed of "frass" 

 and silk. The imago appears in May. The body of the larva is cylindrical. 

 The head is pale brown; the body yellow, with a broad, vascular, reddish 

 brown band." 



The above is Clemens' description. 



The white color of the costal and dorsal streaks, especially the 

 first pair, is often suffused with pale golden. The margins of the 

 second and the third costal streaks, in the middle of the wing, 

 where they are of a dull leaden color, unite with the margins of 

 their opposite dorsal streaks. In some of my specimens bred at 

 Cincinnati from mines on Quereus imbricaria Michx., the dark mar- 

 gin of the second dorsal streak is very heavy and conspicuous.
