Sept., 1913] Pearsall: The Genus Philobia. 191 



Types. — One male and one female from Provo, Utah (Spalding), 

 captured, the former July 26, 1909, the latter June 7, 1910. 



Habitat. — Before me I have fifty-four examples of this species, 

 all taken at Provo in 1909 and 1910, and at Eureka, Utah, in 191 1, from 

 which I have selected eight males and eight females as co-types. The 

 dates, ranging from June 24 to July 30, would indicate the species to 

 he single brooded. 



Philobia versitata new species. 



Expanse, (;^ 22 mm., $ 24 mm. Palpi, front, antennae and collar pale brown- 

 ish ochreous, the cross lines and broad outer band also of this color, intensified 

 and in some examples tinged with rust red at costa. Ground color of body 

 and wings much as in perplexata, but paler, the veins ochreous. Extreme 

 costal edge of primaries with strigae and scattered spots of dark brown. The 

 heavy dark brown central spot is present, but its outline is square, and the 

 parts tend to coalesce. The vein crossings but slightly marked. Marginal 

 lines on primaries heavy, dark brown within excavation, broken into spots 

 below it, almost continuous on secondaries. Fringes within excavation dark 

 brown, with a pale line at base, elsewhere on all wings pale ochre. Discal 

 spots linear on primaries, pale ochreous, sometimes brownish ; round on sec- 

 ondaries, dark brown. Beneath much as above, but the lines and band are 

 pale yellow brown. The central brown spot but feebly portrayed, often not 

 at all. Marginal line and fringe as above. Discal marks linear on primaries, 

 round on secondaries, distinct, dark brown. In the $ the abdomen above 

 sometimes has double spots of pale ochreous in first and second segments, 

 that of the males unspotted. Legs tinged with ochre and sparingly spotted 

 with brownish scales. 



Types. — One 3, Clear Creek, Col. (Oslar), May 27, 1908, and one 

 ?, Rico, Col. (Oslar), July 7, 1905. 



Co-types, two males and two females. Chimney Gulch, Golden, Col., 

 June 21, 1908, one 6 and one $, Clear Creek, Col., May 27, 1908, and 

 one ?, Rico, Col., July 7, 1905. My material is rather scant in this 

 species, but the genitalia show a decided difference from any other 

 form. It is our smallest species in both sexes. Males of cumiilafaria 

 and aspirata are nearly of the same size, but the females of the former 

 are much larger. 



Habitat. — Central Colorado. 



Philobia aspirata new species. 



Expanse, (^ 22 mm., $ 26 mm. Palpi, front, antennae and collar dull grayish 

 ochre, the palpi pale, almost white at tip as is a narrow line on front just
