median interspace. Secondaries white, with a distinct, somewhat lunate 

 blackish terminal line, and a dusky interline in the unusually long white 

 fringes. Beneath white, gray powdered, both wings with small discal 

 spots, and a series of distinct terminal lunules; primaries also with a 

 partial exterior line. 



Expanse, 35 to 37 mm.=1.40 to 1.48 inches. 



Habitat. — Nevada. 



Three male specimens from Mrs. F. O. Herring, all of them a little 

 rubbed, but very much alike so that all the details could be easily 

 determined. The species belongs with hollemani in the pitycJirons 

 series, but differs obviously in the heavy quadrate thorax, the separate 

 ordinary spots, and the pure- white secondaries.

8. CARNEADES CONTAGIONIS, new species. 



Ground color a very pale yellowish or creamy gray, powdered with 

 black scales. Head and thorax without ornamentation. Primaries 

 with the median lines marked by black spots on the costa, and beyond 

 that vaguely indicated. In the best-marked examples the basal line is 

 black on the costa and has a short mark below the median vein. The 

 transverse anterior line has a black costal dot and below the median 

 vein there is a powdered single line, outwardly oblique and reaching the 

 inner margin at nearly the middle of the wing. The transverse posterior 

 line is marked by a black spot above the reniform on the costa, and then 

 by short black marks on the veins, which give a course outwardly bent 

 over the cell and then almost evenly oblique below. The terminal space 

 is a little black powdered and in a vague way deiines an irregular sub- 

 terminal line. Where the powdering is slight there is no trace of the 

 line apparent. Where the powdering is well marked the course of the 

 imaginary line can be made out. There is a series of black terminal 

 lunules. The fringes are concolorous with the rest of the wing. Orbic- 

 ular an irregular black spot without defined margins, which is some- 

 times covered by scales of the ground color. Reniform an indefiued 

 lunule, also without distinct margin, and occasionally more or less obso- 

 lete. Secondaries in the males i^ure silky white, the veins a little darker 

 marked in some specimens and with a distinct trace of a smoky shade 

 at the base of the fringes. In the female they are somewhat smoky. 

 Beneath white, a little black powdered with a more or less obvious discal 

 spot on both wings — most obvious on the primaries — and sometimes 

 with a broken exterior line. 



Expanse, 32 to 35 mm. = 1.28 to 1.40 inches.

Twelve specimens are under examination and they resemble each 

 other strongly. The ground color varies a little in shading, depending
