iimer margin marked by the usual black dash. T. p. Hue outwardly 

 beut over cell, with outward spurs ou the veins making it crenulate. 

 S. t. line pale, very indistinct, interrupted, the usual W-mark some- 

 times barely traceable, preceded by two black sagittate marks in the 

 third and fourth interspace. A row of black terminal lunules. A 

 black basal streak. Claviform variable in size and shape, usually in- 

 completely outlined, suffused by a black shade that extends to the t. 

 J), line. Ordinary spots large, faintly outlined ; orbicular decumbent, 

 elongate, oblique. Renifnrm upright, somewhat indented outwardly. 

 Secondaries pale, smoky fuscous, lighter toward base. Beneath pale, 

 powdery, with common outer line and discal dot. Head aud thorax 

 concolorous; collar somewhat paler inferiorly, patagije with a blackish 

 shade near the dorsal margin. Abdomen with basal tuft only. 



Expands 42 to 44 millimetres, 1.70 to 1.80 inches. 



Habitat. — Colorado, Nevada, Washington, and Kansas. 



Closely allied to hnrgessi in habitus and pattern of ornamentation, but 

 larger, broader- winged, more evenly gray, and with dusky secondaries. 



In this, as in the preceding, the thoracic and basal tufts of abdomen 

 are distinguishable and even well marked, yet they are loose, and the 

 insects as a whole differ in habitus from their nearest allies among the 

 Hadena proper. 



Genus XYLOPHASIA Steph. 



Group vultuosa. 



The most obvious and distinctive character of this group is found 

 in the peculiar maculation of the terminal and s. t. spaces. There are 

 in the former two somewhat triangular dusky shades, the one with the 

 tip near apex of wing and its base just above the middle of outer 

 margin, the point extending inwardly a short distance into the s. t. 

 space. The apex of the second dusky shade is close to the base of the 

 first, and its broadest point is just within the hind angle, where also it 

 crosses the s. t. line; that portion of this shade in s. t. space being often 

 most prominent. The transverse maculation is more or less obsolete 

 and punctiform, except in remissa, and the species are closely allied. 

 The terminal darker shades above described are constant aud form an 

 obvious distinction. Remissa is a peculiarly intermediate form. It 

 strongly resembles in maculation that series of winch indirecta or 

 mactata are tyjiical, and it also has the broad wings of that series. It 

 resembles j^Hi^i>?jrt in ground color, the basal streak, and the structure 

 of the $ genitalia, the clasper only being shorter and more slender. 

 From all the others of the present group it differs by the distinct 

 black shade connecting the median lines and by the large contrasting 

 pale ordinary spots. The typical maculation of the s. t. space deter- 

 mines the reference of the insect to this group. 



The remaining species agree in narrower wings, more or less obso- 

 lete or indistinct maculation, and indistinct aud indefinite ordinary
