AMERICAN LEPIDOPTERA. 79 



margin. A series of black terminal dots. Fringes white or gray. Tlie t. p. line 

 is usually traceable by pale scales and by a leaden or violet gray shading which 

 forms the middle of the dark space toward the inner margin. Orbicular want- 

 ing. Keniform round or nearly so, gray, annulate with pale. Secondaries white, 

 with a narrow smoky outer border, which is lost before reaching the inner angle. 

 Beneath, primaries smoky, yellowish along the costal edge, white on fringes and 

 along inner margin. Secondaries white. 

 Expands 18-27 mm. := .72-1.08 inches.

 Survey); Poncha Springs, Colorado, July 14th (Oslar) ; Black 

 Hills, Montana (Hulst); Kansas in July. 



Two males and five females. Though my largest example ex- 

 ceeds any virginalis before me, yet the latter is, on the whole, the 

 larger species and looks it. Biuocula is much darker as a whole 

 and lacks the distinctive yellow appearance of virginalis. Smaller 

 examples are much like candefacta, save that they always lack the 

 orbicular. 



In venation the secondaries are like virginalis, save that 3 and 4 

 branch further beyond the cell. 



Acuiitia nieskei n. sp. 



Head, thorax and abdomen creamy white. Primaries creamy white to the 

 middle of wing along inner margin and above the median vein nearly to the s. 

 t. line. Basal line marked on the costa. T. a. line marked by a black costal 

 patch, else lost. The t. p. line also begins on a larger or smaller dark costal patch, 

 is a broken upright blackish line far beyond cell, and a series of upright inter- 

 spaceal black marks below the reniform to the inner margin. Median shade 

 marked by a brown band just before the t. p. line below the median vein. Be- 

 yond this portion of the t. p. line is a violet shade to the s. t. line. S. t. line 

 creamy, irregular, broken, preceded by golden brown shades, and in the apical 

 region by black spots. Terminal space broken, with brown, creamy and violet 

 shadings. A broken blackish terminal line. Orbicular a small black dot. Eeni- 

 form obscurely indicated only by scattered brown scales. Secondaries with a 

 yellowish tinge, a little smoky outwardly. Beneath, primaries yellowish, with a 

 dusky discal spot, and augulated. broken exterior line, a dark apex and smoky 

 blocked fringes. Secondaries yellowish, with a dusky discal mark, a smoky patch 

 on the costa giving rise to a slender line, which gets less than half way across the 

 wing, and a narrow blackish outer border. 



Expands 20-22 mm. = .80-.88 inches. 



Hab. — Texas. 



Two males from the old Meske collection, probably taken by 

 Boll. The species is quite characteristic and not easily confused 

 with any of its allies. The primaries are rather narrow for their 

 length, a little subparallel. The secondaries have vein 5 weak, 

 from the cross-vein at some distance from the median ; 3 and 4 

 branch well beyond the end of the cell.
