terior line reduced to two small interspaceal dots, and the upper 

 margin of the pale median vein not in any way relieved. The 

 secondaries, especially in the female, have a smoky appearance, and 

 altogether this seems a duller, more even species than its ally. 

 Besides the difference in the tibial spurs, the sexual leg tuftings of the 

 male are much reduced in antet'odara and the anal tuftings are not at 

 all prominent. The specimens are from Calgary, Vancouver, and the 

 Northwestern United States. 



Calgariana is like phragmatidlcola in size and appearance, except 

 that the color is very decidedly reddish. The white median vein 

 stands out in strong contrast, and in most of the specimens the black 

 margining shade is very distinct. From phragmatidkola the sexual 

 characters separate this species; from anterodara the narrower, more 

 pointed primaries and the color serve as distinctive characters. The 

 secondaries are white in both sexes, the female only with a little fuligi- 

 nous shading and somewhat smoky veins. 



Thus far the species has been received from Calgary- onh'. 



Stolata is altogether different in appearance. The secondaries are 

 snowy white, opaque, and the primaries are straw yellow. The white 

 median vein is well marked, as is the dark shading beneath and beyond 

 it between veins 4 and 5. 



Only the female, from ''Arizona," is at hand at present. 



Oregona is like a very snvdW. j)rag/natidicoIa, more grayish red in 

 color and with semitransparent white secondaries, in which the veins 

 are hardly darker, and there is only a narrow smoky border at the 

 base of the fringes. The secondary sexual characters are much 

 reduced in all respects. The only locality, thus far, is Corvallis, 

 Oregon. 



AVith roseola begins a small group of species in which the median 

 vein of the primaries, though it ma}- be white or jxiler, is not mar- 

 gined or accompanied by any dusky shading. In fact, the wings are 

 practically uniform except for the slightly darker interspaceal streak- 

 ings which are characteristic of the genus. The shadings, which are 

 so well defined in the t3^pical species of this series, are here reduced to 

 vague, dusky clouds, whose location must be understood that they 

 may be recognized. In all of them the secondaries are white, the 

 veins hardly darkened except in the female, in which, also, there may 

 be a slightly dvisk}*^ tinge. 



Roseola., as its name implies, is reddish in tint. It is like calgariana 

 with all the contrasts out; but is somewhat larger and seems broader- 

 winged than that species. It was originalh' regarded as a color variety 

 oifarcta., and has all the characters, except color, of that species. It 

 seems to be not uncommon in the Northern Pacific States and in 

 British Columbia. 



Farda is pale creamy yellow where the preceding is reddish, and is 

 even larger in size. It is anterodara with all the dark shadings out
