until near its tip, then whitish and opening into the 3-4 interspace. 

 Below the median vein is a dusky shading, blackish at base and end of 

 median vein, gray and reddish luteous beyond and below\ The clavi- 

 form barely traceable. Terminal space leaden gray except at apex. 

 Subterminal line marked by black scales or by paler, black-margined 

 points. A small black discal dot. Fringes white, with a yellow line 

 at base and two narrow bhickish interlines. Secondaries white, pearly, 

 semitransparent. Beneath, primaries pale creamy, tending to pinkish 

 along the costa; secondaries pearh^ white, tending to creamy along the 

 costa. 



Expanse. — 1.16 to 1.28 inches (29 to 32 mm.). 



Hahitat. — Wilgus, Cochise County, and southern Arizona (Barnes). 



Three male examples, two of them in fair condition. They are very 

 much alike and there is no doubt as to the distinctness of the species. 

 The genitalic differences have been already referred to, as have the 

 superlicial color characters. The anterior femur has larger tufts than 

 usual in this group and the fore tibia is also well tufted. On the 

 middle and hind legs the tuftings, while well developed, are not 

 especially prominent. 



Type.—^o. 6247, U.S.N.M. 



LEUCANIA NEPTIS, new species. 



Ground color a dull, lifeless, very pale yellow; the dark shadings on 

 the primaries are an equall}^ lifeless yellow or smoky brown. Head 

 tending to rusty brown. Thorax dull luteous; a white line separating 

 the pale from the dark portion of the collar. Primaries with all 

 save internal and median veins dusky; breaking up what in other 

 species is the clear sweep of the paler shade to the apex. The usual 

 trigonate shade above vein 4. The dusky shade below the median 

 shade merges gradually into the paler ground. A small black basal 

 dash; but in few instances can the claviform be traced. Terminal 

 space dusky. Discal dot absent or reduced to a mere point. Fringes 

 whitish with two dusky interlines. Secondaries white with a faint 

 yellowish tint. Beneath very pale yellowish; primaries deeper tinted 

 and more yellowish along the costal region. 



Expanse. — 1.20 to 1,40 inches (30 to 35 mm). 



Hahitat. — Colorado (Neumoegen); Fort Collins, Colorado, August 

 13 (Kearfott). 



Nine examples are before me, eight of them from badly papered 

 specimens. One perfect example from the Neumoegen collection. 



There is an undescribable lifeless shade to all these examples, giving 

 no contrast, no defined impression — all one dull sameness. 



The leg tuftings in the male are better developed than in other 

 species of the group save tetera. In nejytis the anterior leg is not 

 materially more prominent than the others.
