decidedly thickened with long- hair outwardly, not forming ol)vious 

 tufts. On the posterior legs the femoral fringe is much longer and 

 reaches almost to base; the tibite have long thin hair which does not 

 form tufts. The anal tuftings are not very dense exteriorly, but 

 there are two pencils of yellow hair within the genital cavity. 



LEUCANIA ANTEROCLARA, new species. 



Ground color a very pale luteous, almost whitish or creamy. C'ollar 

 paler with three more or less obvious transverse bands which tend to 

 and sometimes are purplish. Primaries obviously streaky but vary- 

 ing in the amount of contrast. Veins paler, the median whitisli. as a 

 rule, and 3 and 4 may be whitish for a part or all their course. A 

 smok}' or olivaceous luteous shading below the median vein. Discal 

 dot a mere point which may be altogether absent. Transverse pos- 

 tei'ior line usually reduced to two l>lack points, never complete. There 

 is a very well-marked tendency to darker streaks above vein 4, em- 

 phasizing the triangular dusky subapical shade. In some specimens 

 a series of small black terminal dots is o))vious. Secondaries white, 

 with a pearly luster or ^^ellowish tinge in the male, with a vague dusky 

 outer shading, the veins dusky; in the female with a broader, smoky 

 border and the entire wings tending to dusky. Beneath, i)rimaries 

 creamy to reddish, more or less powdery, the disk more or less 

 blackish. Secondaries white, the costal margin creamy, powdery. 



Expanse. — 1.40 to 1.56 inches (85 to 39 mm.). 



Ilahitat. — Calgary, Alberta, June 25, July 10, August 13 (Dod); 

 Yellowstone Park, Wyoming, August, (Barnes); Corvallis, Oregon, 

 July 6 (Cordley); (rlenwood Springs, Colorado, June 10 (Barnes). 



Twenty-one specimens are under examination; all the females a little 

 darker and more streaky than the males. 



The differences between this species d^w^ pliragraatidicola have been 

 already discussed. Comparing two series their distinctness is obvious; 

 comparing selected individuals of each series the sexual characters 

 might have to be resorted to. It is suggestive of a local form that I 

 have no itJiragiiiatidieola from the range given for this species, nor any 

 example of this species within the range given ioY phragmat 1 dleol a. 



In the male the anterior femora have long, scaly fringes more than 

 half the distance from base; the tibiw are thickened with scah' ves- 

 titure outwardly. Middle legs with equal femoral fringes for their 

 entire length. TiV)i{e with long hair, capable of partly fan-lik(> ex- 

 pansion in front and at the sides; the outer spurs short and cylindrical. 

 Posterior femora fringed their full length, the fringe longer at l)ase; 

 tibia? with somewhat longer thin hair outw^ardly. The harpes are 

 clothed outwardly with dense hair and scales but these do not form 

 prominent tuftings. Altogether the characters. Avhile of the same type 

 as in phragiiiatidicohi., are very much reduced.
