and at outer fourth a variably marked dusky costal spot; secondaries 

 paler, the costal region black powdered.

Ilahitat. — C'dXg^vy ., Alberta, June 15 to Jul}^ 20; Oregon (Koebele); 

 Pullman, Washington, May 25 (Piper); Nevada County, California 

 (Koebele); Yellowstone Park, Wyoming, July 10; Denver, Colorado, 

 June 30; Chiricahua Mountains, Arizona, July 1 (?). 



This species has the body less robust and the wings broader than in 

 dia., hence it looks decidedly larger, an appearance which was not 

 borne out on actual measurement in all cases. The average runs 

 onl}' 1 or 2 millimeters larger. 



Sixteen examples, varying in distinctness; the Calgar}- specimens 

 are probal)ly all from Mr. Dod, the Yellowstone example is from Dr. 

 Barnes. One example from Calgary is almost as even in color as dia., 

 but has the black basal streak obvious. This latter feature will serve 

 to distinguish the two small species in the group without difficulty. 



There is a decided tendency to a red shading and one specimen is as 

 red as any insueta I have ever seen, the costa in this case being 

 almost white. The single example from the Chiricahua Mountains 

 is a female and in such condition that the reference is not positively 

 made.

LEUCANIA HETERODOXA Smith. 



Leucania heterodo.ra Smith, Trans. Am. Ent. Soc, XXI, 1894, p. 75, pi. v, fig. 7. 



Ground color a dirty luteous gray with a varying reddish tinge. 

 The head may be either a little lighter or a little darker than the 

 ground color. The tuftings of the front legs in the male are conspic- 

 uously darker. Collar with a dusky or black median line either 

 relieved bv paler lines above and below, or with a second, less con- 

 spicuous line just below tip. Disk of thorax and patagifc powdery, 

 the latter tending to a marginal line. Primaries obviously and often 

 conspicuously streaked in the interspaces; the veins white or whitish. 

 Median vein white, forming a white spot at its end, margined by a 

 darker shading. The costal region is paler, sometimes a little con- 

 trasting, until just before the apex. The transverse posterior line is 

 a series of black venular dots, evenl}" curved and nearly parallel with 

 the outer margin. The dark shadings in the wing are above the anal 

 angle and from the transverse posterior line on vein 2 or 3, obliquely 

 to the apex. In some examples there is a costal shade before the apex 

 and in some cases the apex is dusky. There is a series of small termi- 

 nal black dots. The fringes are dusky and have a pale line at base. 

 Secondaries smoky or fuscous, fringes paler. Beneath powdery, vary- 

 ing in tint. Primaries are from reddish gra}" to smoky and have a 

 blackish costal spot toward apex. Secondaries are whitish, becoming 

 more powdery and more reddish in the costal region.
