each terminates on margin are a few yellowish scales, between these is a 

 dark line on the termen, before the cilia. 



Costal fold narrow, not closely appressed, about one-third length of 

 wing, colour brown-madder. Costa beyond fold same colours as fascia 

 and patches that touch it. Before the ovate terminal spot the ground 

 colour is the whitest of any part of the wing, and offers a sharp contrast 

 to the dark outer spot ; it is divided by a line of madder scales. Cilia 

 grayish-white, tipped with fuscous. 



Hing wing pale smoky-fuscous, slightly darker at apex, where a few 

 darker scales form a dot ; cilia paler, preceded by a darker, then a paler 

 line. Under side same, but darker. 



Under side fore wing dark smoky-fuscous, dark scales more intense 

 at apex, shading narrowly into madder on costa before and at apex; cilia 

 gray, preceded by a darker and paler line, an additional faint narrow 

 dark line precedes these ciliate lines on the termen. 



Four specimens. Rounthwaite, July, Marmont ; West Manitoba, 

 Hanham ; Ottawa, Quebec, vi, 26 ; Regina, Assiniboia, Willing. 



Type in my collection. 



Eucosma Heathiana, sp. nov. — Expanse, 17 to 18 mm. Fore wing 

 cream-white, with a dark fuscous dorsal blotch below fold, not touching 

 base and ending before ocellic spot. 



Head, frontal tuft pure white, tuft between eyes tinged with very pale 

 brown in some specimens, in others pure white. Palpi pure white, 

 second joint loosely clothed below and above. Scales below 

 longer than above, and the ends almost concealing tip at outer 

 joint, which is obtuse and cream-white. Antennse white, annulated with 

 light fuscous. Thorax smooth, white, posteriorly stained with fuscous, 

 this darker shade concentrated in form of a dark dot on each side of 

 dorsal line. Abdomen and legs cream-white, tarsi annulated with fuscous. 



Fore wing cream-white, a conspicuous dark fuscous blotch occupies 

 all the space between fold and dorsal margin, except at extreme base and 

 ocellic spot. In the most strongly-marked specimens the dark shade is 

 sharply defined by the line of the fold as far as end of cell, beyond it 

 slightly swells upward, terminating in a rounded spot before the ocellic 

 space. In less strongly-marked specimens the white ground colour more 

 or less overlaps the fold, reducing the width of the dark blotch. This 

 fuscous blotch is more or less overlaid with black scales ; the latter are 

 more frequent in the rounded process at the outer end. Costa from ^ 

 fold to apex dotted with about ten brownish to black short dashes, nearly
