94 THE CANADIAN ENTOxMOLOGIST. 



The palpi are long, slender and (in the dead insect) drooping and 

 slightly divergent, resembling those of Chrysoduta, but more slender and 

 the joints more nearly of the same size ; the third joint is longer than the 

 second. Tongue moderate, scaled. Face full, convex, nearly as wide as 

 long ; head and face smooth, with scales appressed ; eyes globose, of 

 medium size ; antennae about two-thirds as long as the wings, with the 

 basal joint a little elongate. 



Fore wings lanceolate ; the costal vein reaches the margin before the 

 middle ; the cell is acutely closed ; the subcostal vein sends three branches 

 to the costal margin, the first being emitted just behind the middle, and 

 the third at the end of the cell, and the second nearer to the third than 

 to the first ; the median vein divides into three branches, the first of 

 which is opposite to the second subcostal, and the third is at the end of 

 the cell, and between it and the third subcostal branch is a discal ? branch 

 which is furcate before the apex, with a branch to each margin near the 

 apex ; the submedian vein is furcate at the base, and reaches the dorsal 

 margin opposite to the first branch of the median. 



Hind wings almost linear ; costal vein very short ; subcostal straight 

 to the apex ; cell unclosed ; the median divides into three equidistant 

 branches, the second of which attains the dorsal margin about the middle, 

 and there is an independent ? discal branch, which arises at the median 

 and goes to the dorsal margin. 



/. unimaculella. N. sp. 



Palpi white on the upper surface, dark brown beneath, and with about 

 three microscopic whitish specks on the under side of the third joint; 

 tongue and face silvery white ; antennae, vertex, thorax and forewings 

 dark purplish brown ; there is a small yellowish costal spot immediately 

 before the ciliae, but the forewings are otherwise immaculate. Anterior 

 and middle legs and tarsi brown, the tarsi annulate with whitish ; hind 

 legs and under surface of the body yellowish silvery. Al. ex. % inch. 



At a hasty glance this species and Eriphia co?icoloreIla and Elachista 

 concolorella may be mistaken for each other. But the more elongate palpi, 

 narrower wings, finer scales and costal spot, as well as the white upper 

 surface of the palpi, sufficiently distinguish this species. The other two 

 species differ very slightly in shade of color, but may be distinguished by 

 the structure of the palpi, those of Eriphia concolorella being more elongate 

 than those of the Elachista. All three are obscure, plain species.
