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., XXVII, 

 937, 1904)- 

 Lithocolletis saccharella sp. nov. 



Antennas 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 images appear from May to June 

 and again in August. 



Mr. Chambers (Can. Ent. Ill, 130, 1871) confused this 

 species with L. accriella Clem., which it in no way resembles.
