tinge. Thoracic vestiture mostly flattened hair, patagia marked and 

 edged with gray scales, tuftings obvious. Primaries with costal region 

 contrastingly gray or whitish, this shade invading the orbicular and, 

 to some degree, the reniform as well as, occasionally, the inner margin. 

 Basal line marked by a smoky costal spot only. Transverse anterior 

 line geminate, marked on the costa, obsolete through the cell, then very 

 obliquely outcurved in the interspaces; outer portion blackish; evident, 

 inner smoky, obscure, defined chiefly by the somewhat paler included 

 space. A black or blackish shade defines the pale costal space from 

 the base to the transverse anterior line and this shade continues so as 

 to fill the cell around the ordinary spots and the median space above 

 vein 2. Transverse posterior line geminate on the costa, thence single, 

 very slightly crenulate, broadly curved over the cell, well incurved 

 below. Subterminal line gray or whitish, irregular, broken, terminal 

 space darker except at apex, preceded by a dusky subterminal shade, 

 which is best marked on the costa and tends to break up into somewhat 

 triangular spots. There is a faint, terminal, blackish line. Olaviform 

 moderate, black ringed, sometimes concolorous, sometimes gray, and 

 sometimes the margins almost join to make it solidly black. Orbicular 

 narrow, oblique, oblong rather than oval, varying in size, gray-filled. 

 Eeniform moderate in size, kidney- shaped, not extending below the 

 median vein, black margined, then annulate with wliite, the center cou- 

 colorous and variably gray powdered. Secondaries white with a smoky 

 tinge in the male, darker and with a more yellowish shade in the female; 

 fringes white, veins and a discal luuule dusky. 



Expanse, 31 to 37 mm.=rl.24 to 1.48 inches. 



Habitat. — Grarfield County, Colorado, 6,000 feet (Bruce). 



Two males and two females; one of the latter apparently a little 

 dwarfed and crippled, which accounts for the range of size variation; 

 the other examples are 35, 36, and 37 mm., respectively. The species is 

 allied to fur tiv us or idahoensiSj but has none of the red or brown shad- 

 ing, and the transverse posterior line is complete. Aside from this the 

 form of the ordinary spots differs, and this new species has the markings 

 much more obvious and is less even in appearance. 



Type.— Cat. No. 4784, U.S.N.M. 



50. CARNEADES NORDICA, new species. 



Ground color smoky brown, with a more or less obvious red shading, 

 the female with a gray shading over all. Head with a dusky frontal 

 line across the middle. Collar with a distinct black median line, which 

 is tipped with gray; in the male a reddish or rusty shade predominates 

 below this line and leaves a rusty patch at the base of the primaries; 

 in the female a gray shade replaces the red. Thoracic vestiture mixed, 

 patagia defined, tuftings distinct and a little gray tipped. Primaries 

 with the costal legion gray to the transverse posterior line, this shade 

 invading the orbicular and to some extent the subterminal space. The
