and the secondaries white. The sexual tuftings are very moderately 

 developed and nowhere prominent. All examples thus far seen are 

 from middle and southern California. 



Palliseca is decidedly smaller, with narrower, more pointed wings, 

 the primaries having lost almost all trace of maculation. The species 

 occurs in the mountains of Colorado and in southern California; prob- 

 ably in the intermediate region as well. 



In tabular form the species ma}'^ be arranged as follows: 



1. Median vein white or jiale, accompanied I)}' a black or darker shade more or less 



prominent, bnt always obvious 2 



Median vein paler or concolorous, not margined by an obviously darker shade. 9 



2. Male with the anterior legs most heavily tufted; tibia? wdth dense long hairy and 



scaly vestiture capable of fan-like and brush-like expansion 3 



Male with anterior legs least modified ; the tibias not tufted -1 



3. Male antennae lengthily ciliated; primaries creamy yellow with narrow dark 



streaks in the interspaces; secondaries white in both sexes muMlnmi. 



4. ^Middle tibife of the male heavily tufted, the outer terminal spur curved and flat- 



tened, pointed at the tip; lateral ciliations of the antennae prominent toward 



tija; anal tufts very large 5 



^liddle til)i;* of male tufted, but not prominently so; outer terminal spur short, 

 straight, cylindrical; an tennal ciliations not prominent and not longer toward 

 tip; anal tufts moderate 6 



5. Very robust, wings shorter; primaries reddish, very streaky; secondaries fuscous 



brown, even, leg tuftings of male discolorous commoides. 



Less robust, wings longer, more pointed; primaries with narrow reddish streak- 

 ings over a pale luteous base; secondaries white with a smoky outer band and 

 veins _ pliragmatidicola. 



6. Secondaries with veins and margins obviously smoky, the female darker than 



the male 7 



Secondaries white, the veins faintly or not at all marked 8 



7. Primaries smoky gray over reddish, not obviously strigate; the white shade on 



the median vein obscured to near the end of cell imperfecta. 



'Primaries red over a luteous base, the black shade beneath the median vein very 

 prominent calgariana. 



8. Primaries straw yellow, scarcely strigate, transverse posterior line wanting; sec- 



ondaries snowy white, opaque slolala. 



Primaries reddish gray over yellowish; strigate; veins blackish lined; transverse 

 posterior line punctiform, complete; secondaries semitransparent oregona. 



9. Primaries reddish, so narrowly strigate as to seem almost even; secondaries white 



with a yellowish tinge, the veins smoky roseola. 



Primaries very pale luteous, strigate with darker luteous; size large; wings broad; 



secondaries white with the veins yellowish .farda. 



Primaries as before, but with the markings hardly obvious; size smaller; i)rimaries 



narrower, more trigonate, more pointed at apex; secondaries white . . .paUiseca. 



Having given in a general way the essential characters of the groups 

 and of the species to be referred to them, it remains to differentiate 

 the groups before taking up the species individually. 



1. Thorax with a sharp ridge or crest l)ehin(l the collar, ordinary spots present on 



the primaries Group Unipuncla. 



Thorax with a divided crest behind the collar or without obvious tufting of any 

 kind 2
