Varies from pale luteous to dark leather browu. Apex and an irreg- 

 ular large blotch beyond reuiform, paler; terminal space darker. 

 Transverse maculation indistinct. T. a. line geminate, irregularly den- 

 tate, well marked only below vein 1, where it is preceded by the usual 

 dark streak. T. p. line geminate, rather even, interrupted, outer line 

 puuctiform beneath vein 5, included space somewhat paler than ground 

 color. S. t. line pale, distinct throughout, yj mark distinct, preceded 

 by an irregular dark shade, which in the costal region extends to the 

 t. p. line. Claviform faintly marked, a slightly darker brown shade 

 indicating the position of the ordinary black dash. A dark basal 

 streak. Ordinary spots moderately defined ; orbicular variable in size, 

 oblique, elongate ; reniform upright, inferiorly dark filled. A row of 

 terminal black lunules ; fringes dark, cut with pale. Secondaries fusco- 

 luteous, paler at base. Beneath reddish, powdery, with common line 

 and discal spot. Head and thorax concolorous with primaries, patagite 

 darker margined. 



Expands 42 to 47 millimetres, 1.68 to 1.88 inches. 



Habitat.— Canada, Eastern, Middle, and Western States, Arizona, 

 Colorado. 



Rather a common and widely distributed species. The name quwsita 

 was applied by Mr. Grote to dark, well marked specimens with smaller 

 orbicular. 



Xylophasia genialis Grt. 

 1874. Grt., Buflf. Bull, ii, 66, Hadena. 



Pale leather brown with the maculation subobsolete. The s. t. line 

 is usually paler and fairly distinct, the W mark evident. S. t. space 

 usually with darker powderings. The maculation so far as it is trace- 

 able is like that of liijnicolor. It also bears a resemblance to (lubitans, 

 from which it may be distinguished by not having the reniform white 

 marked, and the distinct W of s. t. line. 



Expands 42 to 47 millimetres, 1.68 to 1.88 inches. 



Habitat.— California. 



The species is not common, and has been already sufficiently distin- 

 guished from its allies. 



Group inordinata. 



Two species referred to this group differ from all the others belonging 

 to the genus by brownish-yellow secondaries and distinct white macula- 

 tion of primaries, the W mark of the s. t. line being distinct. The S 

 antennae have the joints marked, and they are furnished with lateral 

 tufts of bristly hair. The genital parts of one of the species is like those 

 typical of the group, and there is in addition to the stout clasper, which 

 is close to the tip, another stout, more slender, corneous hook, rather en- 

 larging toward the tip. The superior apex of tip is deeply excavated 

 and the friugeof spinules is rather sparse. The species belonging here 

 are very readily distinguished and are interesting by their peculiar 

 variations. 



Inordinata was described from Massachusetts, and the type is like
