THE CANADIAN ENTOMOLOGIST. 159 



middle is a rather wide fascia of white and dark brown scales mixed, the 

 dark brown hue prevailing near the costa, where the white is very narrow, . 

 while the white prevails towards the white dorsal margin ; there is an 

 obliquely transverse spot or ridge of raised dark scales about the middle 

 of the wing, beginning on the costa and margined before with white, and 

 before the ciliae is an oblique white fascia nearest the base on the costal 

 margin. Ciliae of a sordid hue, dusted with white. Al. ex. rs inch. 

 Received from Mr. Behrens, of San Francisco, Cal. 



L. unifasciella. N. sp. 



Allied to L. Murtfeldtella Chamb. and the preceding species, and to 

 L. propinqudla Stainton, but still more nearly to L. decorella Steph. The 

 single specimen before me has the palpi broken off. 



Head white dusted with purplish brown scales on the vertex, and all 

 the brown parts of the insect have something of a bluish or purplish 

 gloss. Antennae brown. Upper surface of the thorax brown anteriorly, 

 passing backwards into white at the apex. Fore wings brown dusted with 

 white scales, the white increasing in quantity in the apical part of the 

 wing. There is a large white spot on the base of the dorsal margin, as 

 in Murtfeldtella and propinquella, not quite crossing the wing, and sep- 

 arated, as in those species, from the white spot placed a little further 

 back, which in decorella is connected with the spot at the base ; this and 

 the absence of the white spot within the costal margin, are the most 

 obvious points in which this species differs from decorella. Behind the 

 basal white spot in this species is an ochreous streak in the brown and 

 which ends at the second white spot or patch, which, as just stated, is 

 continuous with the basal one in decorella; this white spot nearly crosses 

 the wing in this species, but does not quite reach the costa, and is dusted 

 with brown and contains on the fold a short dark brown line of raised 

 scales, as in decorella, and which is bordered on the costal side by a small 

 ochreous spot ; thence to the fascia the wing is dusted with white scales 

 and streaked about the fold with ochreous. The white fascia is placed 

 just before the ciliae as in decorella, and is oblique, being nearer to the 

 base on the dorsal than on the costal margin, and before it the wing is 

 more dusted with white and not so strongly marked with ochreous as in 

 decorella, and so it likewise is behind the fascia, though both before and 

 behind the fascia there is a distinct small ochreous spot or streak within 

 the dorsal margin. There is a row of dark brown spots around the apex. 

 (This may represent a hinder marginal line, as the ciliae are injured.)
