Lithocolletis agrifoliella sp. nov. 



Antennas pale ocherous, spotted with brown above, the last five spots 

 more widely separated. Palpi yellowish white, dark brown externally. 

 Face yellowish white. Tuft yellowish in the middle, brown at the 

 sides. Thorax reddish ocherous, with a few dark scales on the patagia. 

 Forewings reddish ocherous, somewhat shining. At the basal fourth 

 is a perpendicular white dorsal streak dark margined externally and 

 reaching to the fold. A little farther back is a nearly perpendicularly 

 placed white costal streak, convex outwardly beneath the costa and also 

 attaining the fold, slightly beyond the dorsal streak; it is strongly dark 

 margined externally; its short internal straight dark margin is opposite 

 the external dark margin of the first dorsal streak. Near the base, the 

 costal portion of the wing is of a smoky hue. Placed diagonally across 

 the wing toward the base on a line with the internal edging of the first 

 costal streak are two black transverse spots, the first just above the fold, 

 and the second nearer the base just below the fold; sometimes with a 

 few whitish scales internally. At about the middle of the wing length 

 is a broad oblique costal streak, internally dark margined near the costa, 

 and its external dark dusting continued as the external dusting of a 

 much narrower dorsal streak, whose apex just meets that of the costal. 

 At the angle, the dusting is very dense on a white ground, and is con- 

 tinued backward as a broad band, nearly one-half the breadth of the 

 wing, to a point between the third costal and dorsal streaks The third 

 costal streak, which is sometimes a spot, not touching the costa, is in- 

 wardly oblique and externally dark margined. Opposite it is a long ob- 

 lique dorsal streak, whose external dark margin is continued into the 

 dusted apex, and which usually unites with a sickle-shaped costal streak, 

 lying above the dusted apex, and concave toward the costa. The dark 

 margin of the third costal streak is sometimes continued along the 

 costa to this last streak. Cilia ocherous, with a dark brown hinder mar- 

 ginal line through their middle. Alar expanse 7-5-9 mm. Hindwings 

 gray, with a bluish metallic luster. Cilia fulvous. Abdomen 

 dark bluish metallic above in the male, pale yellowish beneath, with a 

 median line and diagonal marks on each segment dark. In the female 

 with the last two or three segments and tuft ocherous, pale ocherous 

 beneath, and marked as in the male. Legs whitish, the first two pair an- 

 nulate with black ; hind tibiae shaded with ocherous and black scales, 

 tarsi tipped with black.
