258 THE CANADIAN ENTOMOLOGIST. 



Theie are about 200 specimens before ine, nearly evenly divided as 

 to sex, and most of them in very good condition. The males are as a 

 whole decidedly paler in colour than the females, and the tendency to the 

 yellowish shading is best marked. The relationship is to vicina, which is 

 darker, more bluish gray, has the claviform prominently marked and the 

 ordinary spots of different form. There are other differences, but these 

 will suffice to distinguish the new form. 



Hade7ia erica, n. sp. — Ground colour bluish ash gray, marked with 

 darker gray and blackish. .Head with a black frontal line ; collar with a 

 narrow blackish line ; patagia with a blackish submargin, disc powdered 

 with blackish. Primaries with the lower half of basal space, the apical 

 region and the submedian interspace between t. p. and s. t. lines much 

 paler gray and with an ochreous tinge, giving the wings tlie appearance of 

 having three pale blotches ; this feature more obvious in the female. 

 Basal line geminate, often lost, extending to a short black somewhat 

 curved basal mark. T. a line geminate, inner portion vague, gray, outer 

 blackish; the line as a whole a little outcurved and somewhat drawn in 

 on the veins. T. p. line geminate on the costa, the outer portion lost 

 before it is curved over the cell, the incurve deep. The s. t. line is pale, 

 marked just before the apex, well drawn in and obscured by the apical 

 pale area, and then with a very even and well marked bisinuation to the 

 inner margin. There is a series of black terminal lunules and a yellow 

 line at the base of the fringes whicli are cut with blackish. The orbicular 

 is ovate, usually well defined, edged with black scales, with a whitish 

 annulus, concolorous or paler gray. Reniform oblong, a little oblique, 

 sometimes constricted, occasionally nearly kidney-shaped, inwardly 

 marked by a whitish, outwardly by a black line, top and bottom not well 

 defined. The claviform is black lined, large, broad, usually extending 

 across the median space, concolorous. Secondaries whitish in the male, 

 srnoky in the female, veins blackish marked, a more or less defined 

 extra-median line and a discal lunule. Beneath gray, powderings of 

 primaries in the female nearly black, secondaries with an outer line and 

 discal spot. 



Expands: 1.12-1.32 inches = 28-32 mm. Habitat: Stockton, 

 Utah, June and July. 



Nine males and eleven females, most of them in good condition, from 

 Mr. Tom Spalding. Th^re is little variation, except what is duo to the 

 differences in contrast. The species is allied to characta, Grt., but differs 

 obviously when a series is at hand.
