streaks the ground color is bright ochreous brown, this shade narrowly margining 

 upper half of termen. There is a small white dot on termen immediately below 

 apex. Cilia on upper half light ochreous brown, mottled with darker brown and 

 gray, with a few black scales in apex, the lower half, opposite white ocellic area, is 

 white. 



Hindwing . — Light smoky brown, cilia cinereous, preceded by a gray line ; 

 underside the same. Undeside forewing darker smoky brown, costal spots faintly 

 repeated. 



Ten specimens, Cincinnati, Ohio, June 6-23, Miss Braun ; Pitts- 

 burg, Pa., July 3, Henry Engel. Cotypes in Merrick Museum, Miss 

 Braun's and my collections. 



This species is like similana Hbn. (Europe) and has been fre- 

 quently so named. The wings are narrower and the arrangement of 

 costal spots and dorsal patch different. In shape and general appear- 

 ance dorsisuffusana is more like otiosana Clem. 



Eucosma medioviridana, new species. 



Expanse 16-17 mm. 



Head, palpi, antenna and thorax light mouse-gray ; apical joint of antenna 

 blackish brown ; abdomen light fuscous ; legs whitish, shaded with gray in front. 



Forewing. — Outer two thirds pale apple green, inner third conspicuously 

 darker. The basal area at middle of wing extends to inner third, its outer edge is a 

 black line, obliquely outward from costa to middle, thence inward to dorsum with an 

 indentation between fold and dorsum ; there is an inwardly oblique line in the middle 

 of this space, beginning at costa and ending below fold, this starts as outwardly 

 oblique on the $ costal fold, then turns inward. Between costal fold and lower 

 median vein, is overlaid with darker apple green, on a dark gray ground, below it is 

 mottled gray and brown, this is succeeded in the outer half of the basal area by a 

 patch of light ochreous brown, widest on dorsal margin and tapering to a point at 

 upper third. Beyond the basal area the balance of wing is pale gray, more or less 

 heavily overlaid with pale apple green, this color is most pronounced in the middle 

 third of wing. It is traversed by faint irregular darker lines from the costa; two 

 from beyond middle of wing enclose an obscure narrow dark gray fascia to tornus ; 

 half way between this and an apex an irregular line circles the outside of ocellic 

 space, the latter is not defined. Cilia dark gray. 



Hindwing. — Brownish gray, underside the same; underside forewing dark 

 smoky gray. 



Six specimens, Ottawa, August 17-21, C. H. Young; New 

 Brighton, Pa., August 25 to September n, H. D. Merrick and 

 Henry Engel. Cotypes in Merrick Museum, Young's and my collec- 

 tions. 



This species, in the shape of the wings and general markings, is 

 very similar to pulsatillana Dyar, it can be separated by the green 

 shading, which is absent from pulsatillana ; I would place it between 

 the latter and nisella Clerck.
