Dec. 1905.] Smith: New Species of Noctuid.*: for 1905. 195 



Orbicular large, round, concolorous, edged by black scales and some reddish powder- 

 ings. Reniform large, kidney shaped, filled with reddish powderings ; edged with 

 black scales ; the space between the spots somewhat darker. Secondaries dull, pale, 

 smoky yellowish, tips of fringes paler. Beneath smoky gray, powdery. 



Expands : 1.56 inches = 39 mm. 



Habitat. — Banff, Alberta; N. B. Sanson, "Museum," July 11, 

 1902. 



One good male, received through the courtesy of Dr. James 

 Fletcher. The species is an obvious ally of bicarnea, with a similar 

 excavation in outer margin of secondaries below apex ; but it lacks 

 the characteristic shadings and the details of maculation, especially in 

 the ordinary spots, are quite distinct. 



Euxoa sotnia, new species. 



Ground color very pale gray with a luteous tinge, densely powdered with black 

 scales, especially in the female. Collar usually with a more or less obvious transverse 

 line ; but that is often wanting. Thoracic vestiture a mixture of fine and flattened 

 hair, varying somewhat in proportion ; the collar, patagia and crests well marked in 

 good examples ; but not prominent. Primaries rather narrow, elongate with the apex 

 more reduced than usual ; ail the lines present, but broken and more or less obscured 

 by the powdering. Basal line geminate, obscurely marked. T. a. line upright, or 

 only a little oblique, a little outcurved in the interspaces ; geminate, inner line tend- 

 ing to become lost, outer diffuse, more or less broken ; sometimes the entire line 

 hardly traceable. T. p. line geminate over costal region, abruptly bent over cells 

 then very even to the inner margin, the inner line more or less diffuse, sometimes 

 nearly even, sometimes lunulate and sometimes crenulate ; but always traceable. S. 

 t. line irregular, always traceable, variably distinct ; sometimes defined by an even 

 dusky terminal space; sometimes also by a preceding shade; occasionally only 

 picked out by light scales. Apex usually concolorous, the inception of s. t. line on 

 costa often preceded by a blackish shade. A series of terminal dots or small lunules 

 is often present ; but as often wanting. Fringes variable. There is a diffuse dusky 

 median shade that darkens the cell between the ordinary spots, and then runs close 

 to and parallel with t. p. line, often darkening the outer part of median space. This 

 shade is variably developed but always recognizable in some form. Claviform want- 

 ing. Orbicular round, varying in size, rarely defined, sometimes concolorous ; 

 sometimes discolored ; rarely with a dark center. Reniform of good size, kidney- 

 shaped, never completely defined, sometimes scarcely traceable. Secondaries white, 

 with a narrow dusky edging in the male : in the female they are sometimes equally 

 immaculate ; but the tendency is to a smoky outer border beyond an extra-median 

 line, and sometimes a discal spot is also traceable. Beneath, more or less powdery, 

 sometimes almost immaculate, ranging to forms in which the disc of primaries is 

 blackish, and there is an obvious extra median line on both wings. 



Expands: 1. 15- 1.38 inches = 29-34 mm. 

 Habitat. —Stockton, Utah, September 9-24.
