before the middle. Two fuscous spots before the eud of the fis- 

 sure, and beyond them, on the first lobe, a fuscous dash, pointing 

 toward the upper spot, both together forming an exclamation 

 point ; above, the costa is spotted with fuscous. Fringes around 

 the fissure white ; along the outer margin cinereous, with a fus- 

 cous line at their base, but interrupted with white on the middle 

 of the anterior and at the upper angle of the posterior lobe. Hind 

 wings fuscous, with brownish scales. Fringes brownish. 



Habitat. California, Oregon. Early stages and food plant 

 unknown. 



STENOPTILIA MENGELI, n. s. 



Expanse of wings, 20 mm. Head, palpi, thorax, abdomen and 

 legs dark ashy gray. A fine white line occurs over each eye. 



Fore wings ashy gray and glistening ; a few dark fuscous scales 

 on the first lobe form an ill-defined longitudinal stripe on the mid- 

 dle ; a fuscous spot at the end of the cleft and a less distinct one 

 on the middle of the cell. Hind wings ashy gray. Allied to S. 

 exclamationis and S. semicostata. 



Early stages and food plant unknown. 



Described from ten specimens, in poor condition, in the collec- 

 tion of the American Entomological Society, taken by Mr. L. W. 

 Mengel at McCormack's Bay, North Greenland. In the " Ento- 

 mological News," Vol. V., p. 129, I gave an account of McCor- 

 mack's Bay, where these insects were taken. 



STENOPTILIA SEMICOSTATA. 

 Mimeseoptilus semicostatus Zell., Beitr., p. 123 (1873). 



Expanse of wings, 18 mm. Head grayish, with a fine white 

 line above the eyes. Antennae grayish, white toward the base. 

 Thorax dusted with brown in front, whitish behind. Abdomen 

 slender, pale yellowish, with two black dots on the end of each of 

 the three segments before the last. Legs whitish. 



Fore wings brownish gray, shading into pale reddish ochre along 

 the hind margin and upon both lobes. In the middle of the space, 

 between the base and the fissure, is a black dot. At the fissure, 

 at the beginning of the second lobe, is a similar dot, and above it, 

 in one example, is a larger but very distinct wisp-like mark. One 

 example has in the middle of each lobe a fine, brown longitudinal 

 streak ; upon the first lobe it is short and in the middle, upon the 

 second it is long and reaches quite to the hind margin. Fringes 

 of hind margin of first lobe whitish at the base, gray outwardly ; 

 fringe of outer margin pure white with two black dots, one behind
