12. CARNEADES EXCULTA, new species. 



Ground color a soft, dark, red-brown, overlaid by gray. Head and 

 thorax immaculate; collar without a transverse liue. Vestiture, 

 slightly flattened hair, the tuftings indistinct. Primaries, at first 

 sight immaculate. The median lines indicated on costa by dusky 

 spots and, under a lens, the transverse anterior line can be traced 

 across the wing by a series of golden brown scales. Terminal space 

 slightly darker, thus feebly indicating an irregular subterminal line. 

 Ordinary spots marked by somewhat darker, lead-colored scales and, 

 under the lens, outlined by golden brown scales. Secondaries pale, 

 smoky yellow, darkening to smoky outwardly, fringes whitish yellow. 

 Beneath whitish, powdery costal and outer margins darker, smoky. 

 " Expanse, 33 mm. = 1.32 inches. 



Habitat. — Northwest British Columbia. 



A single male, received from Mr. B. JSTeumoegen some years pgo and 

 never satisfactorily placed. It resembles excogita, at first sight, but is 

 more stumpy winged, lacks the prominent black liue on the collar, and 

 has the maculation much more completely obsolete. 



13. CARNEADES N^EVULUS, new species. 



Ground color dull, powdery, ashen gray. Head and thorax immacu- 

 late, collar with a dusky line just below tip; but this is obscure in most 

 examples. Vestiture composed of long, flattened hair, anterior crest 

 not obvious, posterior tufting fairly well defined, patagia not marked. 

 Primaries with a rough, powdery appearance, none of the maculation 

 well defined. Basal line geminate, smoky, interrupted. Transverse 

 anterior line geminate, smoky, the two ijarts about equally obscure, 

 outwardly oblique and rather evenly outcurved in the interspaces. 

 Transverse posterior line obscure, fuscous, geminate on the costa, 

 rather squarely bent over the cell, inwardly oblique and very even 

 below this point. Subterminal line irregular, punctiform, pale, some- 

 times defined by a vague preceding shade, or a slight deepening of the 

 terminal si)ace, and sometimes wanting altogether. A series of black- 

 ish terminal lunules, followed by a yellowish line at the base of the 

 fringes. ISTo obvious median shade or line. Claviform very small, and 

 never completely outlined by blackish scales. Orbicular variable in 

 size and shape, concolorous, outlined by black scales, complete only 

 when it is small and round. Reuiform large, kidney-shaped, extending 

 below the cell, concolorous, incompletely black ringed. Secondaries 

 dirty white in the male, with a somewhat defined, smoky, powdery 

 outer border, a smoky terminal line, and a discal lunule, the veins being 

 also smoky ; in the female they are smoky throughout, but become more 

 whitish and transparent basally; discal lunule evident. Beneath, 

 primaries gray, powdery, secondaries white, powdery along costa, all 

 wings with a discal spot; no evident outer line.
