AMERICAN LEPIDOPTERA. 219 



long; apices pointed ; external margin oblique, even ; the wings satiny 

 white." 



This is Mr. G rote's description. The genus is unknown to me. The 



species is 



E. notatella, Grt., Can. Ent. 14, p. 75. — Wings satiny white; primaries 

 with two black dots on the cell ; a row of black points on external margin. " Size 

 of bimatris." Expands li inches, 30 millim. 



Habitat. — Montana. 



I should like to see this insect— an examination of the differences 

 between this genus and Antaplaga would prove instructive. 



IIIMOTIIIS. Hb. 



Eyes naked, globose ; head not retracted ; clypeus full, bulging, but 

 never projecting in a knob or tumor (Beule); palpi small, moderately 

 fringed beneath ; tongue strong ; body stout, strong, with lengthy recum- 

 bent hair, forming no distinct tufts on thoracic dorsum ; abdomen stout. 

 conic, 9 ovipositor not extruded ; tibiae spinose ; anterior not abbrevi- 

 ated and terminated by a spine at inner and another at outer edge (PI. 

 VII, fig. 6) ; wings moderate, with primaries somewhat produced at 

 apex and roundedly oblique outer margin. 



The venation of the group in general, and of this genus in particular 

 is shown, PI. VII, fig. 46. 



As above limited the genus embraces Ohloridea rhexiu, and those 

 species placed by Lederer in the second section of the genus, excluding 

 therefrom Ononis s. v. {Mel. oregoua Hy. Edw). Of the species re- 

 ferred to this genus in his ; ' New Check List." Mr. Grote has since 

 placed hirens with Tami/a, with the type of which it has not the slight- 

 est affinity (Can. Ent. 1-1, 175). Spinosea, (in., drops from the genus 

 while Oxylos citrinellus is added. This latter insect does not fit into 

 He/i'othis as I have limited it and I have not included it. Of the others 

 I do not know (jupafux, which may or may not belong to the genus as 

 above limited, but which Mr. Grote (he. rit.) includes in the genus as 

 he proposes to limit it. Cupes, Grt., which is also included, does not 

 belong to this genus, the structure of the anterior tibia (PI. VI I. fit:. '2'.'> i 

 sufficiently separates it, while the vestiture instead of being hairy is 

 composed of scales and flattened hair. The markings of primari s only 

 ally it to the species properly in the genus (in my opinion i and the spe- 

 cies was probably described as Hellothis merely because it looked like 

 one, and without any examination of the structure. 



As limited by me, and excluding Inpatus, which I don't know, the 

 species stand follows :
