below that point. S. t. line broken, concolorous, defined by a series of irregular 

 brown spots and shades iu the s. t. space and a generally darker tint in the ter- 

 minallunules. Claviform small, concolorous, outlined by a narrow black line. 

 Orbicular round, somewhiit paler, variable in size, defined by black scales and by 

 a blackish shade preceding it and continuing between it and the reuiforni. The 

 latter is large, upright, somewhat constricted medially, inferiorly dusky, else 

 concolorous. Secondaries fuscous, with a faint discal lunule. Beneath paler 

 than above, powdery, with a broad outer dark band and a dark discal lunule on 

 ail wings. Expands 35-38 mm. ; 1.40-1.52 inches. 



i/a6.— Colorado, Bruce; Nos. 70, 207, 326. 



Mr. Bruce has sent me three specimens, all of them tnales, and all 

 much alike. One of them is labeled " Salida, 4, 18, 88," the others 

 are more recent captures. The species is simply and quite normally 

 marked, and very much resembles some forms of brunneigera in 

 api^earance, save that it lacks the iiiedian shade line and is more 

 robust in appearance. The antennte of the male are pectinated, and 

 the species is therefore allied to the preceding (siccata), from wliich 

 it differs at a glance by the totally different ground color, ami in 

 many details of maculation. 



€ariiea<le»i segregata n. sp. (PI. iv, fig. 6)— Ground color very pale lu- 

 teous. Head grayish, collar pale creamy yellow inferiorly, limited by a black 

 line, above which the color is dull gray. Thorax dull luteous gray, disc more 

 yellowish. Primaries luteous, paler along the costa and internal margin, a 

 smoky shade through the centre of the wing to the t. p. line, becoming blackish 

 in the cell, and again appearing in the terminal space. Basal line visible only as 

 a pale spot cutting a basal black dash, which extends below the median vein. 

 T. a. line pale through the dusky central shade, obsolete in the costal region and 

 along the internal margin. T. p. line obsolete, marked only as limiting the outer 

 margin of the central dusky shade. S. t. line variably marked, pale, emphasized 

 by the dark terminal space and by dusky or black preceding dashes and shades, 

 varying in the specimens. A series of black terminal lunules. Fringes whitish. 

 Claviform moderate in size, black ringed and dark filled. A black, slender line 

 extends from its tip to the anal angle through the middle of the submedian in- 

 terspace. Orbicular moderate in size, oblique, open to the costa, narrowly black 

 ringed and centred with a very pale yellow. Reniform upright, kidney-shajied, 

 narrowly black ringed, annulate with white, and gray centred. Secondaries in 

 the male whitish, with smoky veins and an indefinite smoky outer border; the 

 fringes white. Beneath whitish, immaculate, except for a dusky discal dot. 

 which, in the secondaries, is faintly visible on the upperside. Expands 31-36 

 mm.; 1.25-1.45 inches. 



Mab. — Colorado. 



Seven specimens of this species are before me, all of them males- 

 Two of them are from Mr. Bruce, the others from various sources, 

 none of then) with the exact locality. The insect resembles ivUsonil 

 most nearl}' in color and in general appearance, but differs in that
