(LITHOCOLLETIS) NOVEMBER, 1859. 69 



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 last, black- 

 margined toward the base, the third but faintly, and the costa 

 black from the base to the first costal streak. Three silvery 

 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 pupa- 

 tion 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. 

 There is doubtless a spring brood, but I have not searched 

 for the larva during the season. 



5. L. basistrigella* Antennae silvery. Front silvery, 

 tuft fulvous, mixed with silvery. Thorax pale, reddish- 

 golden, with a white streak on each side and one in the 

 middle. Fore-wings shining ochreous-saffron, with a slender 

 unmargined white basal streak in the fold, a white basal 

 streak along the costa, narrowly dark-margined on the ex- 

 treme costa, extended to the first costal streak, which is 

 silvery-white, very oblique and unmargined ; behind this are 

 three small costal streaks of the same hue, the two central 

 dark-margined internally. Opposite the first costal streak is 

 a long, very oblique, silvery-white dorsal streak, extended 



* I received three specimens of this from Dr. Clemens; it is near our Euro- 

 pean Suberifoliella, Zell., but smaller, the basal streak shorter, the subapical 

 streak more distinct and the ground colour darker. The exp. al. (omitted by 

 Dr. Clemens) is 4 lin. H. T. S.
