Sept., 190S.] KeARFOTT : TORTRICID.E AND TiNEINA. 185 



Foi-ezving. — Stone gray, marked with black. The base of costa is blackish 

 gray, from the inner fifth a short black dash joins an oblique inverted comma-shaped 

 mark that extends to fold. Between this and base there is a small black dash in the 

 middle of wing and a dot on dorsal margin close to base. In the middle of cell 

 are two black dots, the upper one nearer the base ; above them the costa is slightly 

 sprinkled with black scales. At the outer third of costa there is a rounded shade of 

 blackish scales, extending down to middle of wing ; on the inner edge of this shade, 

 at end of cell, is an oblique, elongated black spot. The terminal line is a row of 

 dots, beginning with the costal cilia and following the termen to tornus, one dot 

 between each two veins ; before these dots the venal interspaces are very slightly 

 dusted with black. Cilia concolorous. 



IJiii(iwi"g. — Very light gray, cilia with a faint yellowish tinge; underside the 

 same, with a clouding of fuscous along costa and in apex. Underside forewing dark 

 fuscous, with the terminal dots faintly repeated. 



Six specimens, Aweme, Manitoba, June 13-16, Norman Criddle ; 

 Rounthwaite, Manitoba, June 15, L. E. Marmont. 

 Type in my collection. 

 The shape of wings and venation is exactly like figure of Gelechia 



v*>-> serotinella Busck, Proc. U. S. N. M., XXV, 1902, the palpi structure 



, agrees with G. alternaiella. The markings of the species are close to 

 ci! fondella Busck ; it can easily be separated by its larger size, the sepa- 

 rated dots on disc and by the prominent terminal line of black dots. 



Gelechia alternatella, new species. 



Expanse 14. 5-1 5. 5 mm. 



Thorax and head mottled brown and bronzy black, darkest posteriorly, face 

 brown mixed with white scales ; labial palpi, second joint, white at base both inner 

 and outer surfaces, lower edge mottled with dark brown, this mottling extends over 

 the outer half both inside and out, apical joint very dark brown, sparsely dotted with 

 white ; antenna black, annulated with white ; abdomen, anterior edge each seg- 

 ment dark bronzy brown, posterior edges broadly white, and segment brown ; legs 

 black, annulated with white at joints ; tongue long, basal third scaled with whitish 

 gray in front ; ocelli present. 



Forewi7ig. — There are four dark brown transverse streaks or fasciae, on a whitish 

 gray ground color, all of nearly equal width dividing the surface into sharply defined 

 alternate streaks of these colors. The brown is as follows : from the costa at base 

 an oblique fascia goes below fold but does not reach dorsum ; the base before and 

 below it is whitish gray ; before the middle is a transverse fascia slightly broader on 

 costa and denticulate in middle, on inner edge ; there is a broad shade of brown on 

 costa from middle to outer fourth, occupying the upper third of wing, from the mid- 

 dle of this a darker brown fascia curves obliquely to tornus ; there is a broad subter- 

 minal fascia from apex to tornus ; terminal line, beyond this is whitish gray. The 

 subterminal fascia makes a small brown spot in the costal cilia before apex, and in 

 the whitish space before it is another brown cilial spot on costa. Cilia gray at apex, 

 shading into whitish below, with three small clusters of darker scales on upper half 

 of termen. The gray-white ground color is somewhat mottled with brown scales.
