AMERICAN LEPIDOPTERA. 33 



According to Mr. Busck a specimen of this European species 

 from Canada is in the U. S. Nat. Mus. A specimen without locality 

 label and probably determined by Zeller is in the Cambridge 

 Museum. 



M. dorsistrigella Clem.— Dyar's List, p. 571, No. 6502. 

 I here give Clemens' description of this species: 



"Labial palpi yellowish, dark brown externally, third article yellowish. Head 

 and front very pale yellow, tinged with dark brown on the sides above the eyes 

 and at base of antennae. Anteume dark brown. Thorax dark brown, with the 

 disc, very pale yellow. Forewings blackish brown, somewhat tinged with 

 obscure reddish, with a dorsal streak along the inner margin, whitish or pale 

 yellowish white, and usually somewhat dilated above the anterior angle; with a 

 costo-discal patch of the same hue, and the costa punctuated with pale yellowish 

 atoms, which become small spots toward the apex of the wing and on the poste- 

 rior margin. Hind wings pale brownish, with a reddish hue; cilia gray. Exp. 

 4.75-6.00 lines." 



To this I wish merely to add that the thorax should be described 

 as pale yellow, patagia dark brown. Abdomen above ochreous fus- 

 cous ; body beneath and legs sordid grayish yellow. The antennae 

 pale fuscous. Two type specimens in good condition are in the 

 Clemens collection at the Academy of Natural Sciences, Phila. 



Exp. 12.0-14.5 mm. ; 0.48-0.58 inch. 



Hab. — Atlantic States; New Mexico (Las Vegas). 



Common at light and on trunks of trees. 



M. crocicapitella Clem. — Dyar's List, p. 570, No. 6488, cited as synonym. 

 The author describes this species as follows: 



"Labial palpi yellowish, dark brown externally. Head and front saffron yel- 

 low. Forewings dark fuscous, with dispersed saffron yellow scales, especially 

 along the costa, with a saffron yellow dorsal streak and a paler, nearly round, 

 discal spot. Hindwings pale brownish gray. Exp. al. 4.50 to 6.50 lines." 



The "paler, nearly round discal spot" mentioned in the descrip- 

 tion is the vitreous spot and is situated in the middle of the wing- 

 length. Thorax yellow, patagia dark brown. Legs and underside 

 of body are pale yellowish, dusted with fuscous. 



Exp. 11.0-16.5 mm. ; 0.44-0.76 inch. 



Hab. — United States. 



Have seen specimens from every fauna] district. Specimens from 

 California are generally larger than the eastern forms. Heretofore, 

 this species has beeu confounded with the European M. ferruginella 



TEANS. AM. ENT. SOC. XXXI. (5) JANUARY. 1905.
