iill the basal space, continued below vein 1 to meet the same shade from 

 the outer i)ortious of tlie wing", where it darkens toward the oblique 

 apical patch. The orbicular is not marked m any of the specimens 

 now before me, but the reuiform is indicated in some by a few raised 

 black scales, forming a more or less evident luiiule. Secondaries smoky 

 gray to brown, darker in the male, the secondaries with a usually evi- 

 dent discal lunule and an occasionally marked median line. 



Exjianse of wings, i*.'> to -i7 mm. = 0.110 to 1.00 inches. 



Habitat. — Canada to District of Colun»bia; Minnesota; Iowa; Dis- 

 trict of Columbia in June. 



This is a very pretty, very distinct, and not very common species, 

 which is recognizable at once by the peculiar shape of the median space, 

 inwardly marked by the united median lines. 



In tue male the ]»aler shade has just a feeble violet tinging.

Ground color brown, varying in shade. Head brown, with gray 

 scales intermixed, the latter sometimes predominating. Thorax with 

 the collar brown, gray tipped, dorsum brown anterioily, posteriorly 

 gray; sometimes the entire thorax gray, and sometimes entirely brown 

 with a gray admixture. Abdomen fuscous. Primaries with the median 

 space dark brown to blackish, this shade extending through the basal 

 space and obscuring the transverse anterior line, which is faintly 

 marked on the costa. The inferior portion of basal space is more or 

 less white powdered, this i)ale shading extending beneath vein 1 and 

 connecting with the similar shading beyond the transverse posterior 

 line. The transverse anterior line extends apparently from the costa 

 at the extreme base of the wing obliquely outward to the submedian 

 vein at one-ftfth of its distance from base, then bends backward and 

 downward to the margin, very feebly marked below the vein. As a 

 matter of fact, the true transv^erse anterior line is superiorly obsolete 

 or only traceable, and a longitudinal hue Joining it below the cell gives 

 a false impression, which is conveniently utilized for descriptive pur- 

 poses. The transverse posterior line is black, followed by a white line,
