104 ENTOMOLOGICAL NEWS. [March, ’08 
By some mistake this species has been referred to as Lithocol- 
letis populiella Chambers by Mr. Busck in his paper “Tineid 
Moths from British Columbia” (Proc. U. S. Nat. Mus., 
XXVII, 770, 1904) and by Dr. Harrison G. Dyar in “Lepidop- 
tera of the Kootenai District” (Proc. U. S. Nat. Mus., XX VII, 
937, 1904). 
Lithocolletis saccharella sp. nov. 
Antenne pale ocherous, beyond the basal third annulate with dark; 
several joints toward the tip dark. Palpi shining white. Face shining 
white. Tuft whitish, golden toward the sides. Thorax and forewings 
ocherous. A white stripe on each side of the middle of the thorax is 
continuous with a very oblique curved white streak at the inner angle of 
the forewing. This streak, which is sometimes dark margined behind, 
extends to the fold and is usually prolonged along the fold to unite 
with the first dorsal streak. The first dorsal streak begins at the basal 
fifth, is oblique and curved, and extends slightly more than half way 
across the wing. The second dorsal streak, at about the middle of the 
dorsal margin, is also oblique and curved, and near the costa, its apex 
meets that of the first costal streak, which is short, oblique and placed 
slightly beyond the middle; thus forming an acutely angled, interrupted 
fascia. The second costal streak, at the apical fourth, is sometimes al- 
most overlaid with black scales. Above the dorsal cilia is a long oblique 
white streak. All the streaks are dark margined externally. Apical 
portion white dusted with black. There is considerable variation in the 
extent of the black dusting, which sometimes extends to the tornus. 
Marginal line in the cilia brownish ocherous. Cilia pale ocherous. Alar 
expanse 5-7 mm. Hindwings pale grayish ocherous. Cilia pale ocherous, 
Abdomen gray above, pale ocherous below. Anal tuft ocherous. Legs 
whitish. Hind tarsi faintly tipped with black. 
Described from specimens bred at Cincinnati, Ohio. I also 
have specimens taken in Essex Co. Park, N. J., by Mr. W. D. 
Kearfott. 
The mines of this species are very common on Sugar Maples, . 
Acer saccharum, Marsh. and Acer nigrum Michx., as many as 
25 or 30 mines sometimes occurring on one leaf. ‘The mine is 
a small irregular blotch on the upper side. The pupa is not en- 
closed in a cocoon. The imagos appear from May to June 
and again in August. 
Mr. Chambers (Can. Ent. III, 130, 1871) confused this 
species with L. aceriella Clem., which it in no way resembles.
