outwardly. Costal region of the areas on either side of the basal line dark 

 brown. Extradiscal line white, somewhat lost in the dusky scales just out- 

 ward of this line, begins on costa one-third in from apex, curves inward to Mj, 

 then to Cuo is produced outwardly in two scallops and then runs irregularly 

 inward to inner margin, sending a spur to the intradiscal line in the sub- 

 median space. The area between the intra- and extradiscal lines is filled in 

 with light and dark brown, the darker color occupying the costal and inner 

 marginal regions and a portion of the inner central space between Mj and Cuo ; 

 the lighter color occupying the remainder. Submarginal space with a costal 

 blotch formed of the dusky scales, which latter also occasionally form one or 

 two brokenly scalloped lines following in general the extradiscal line. A large 

 subapical patch on outer margin sending two or three rounded teeth inwardly. 

 Terminal line fine, incomplete, showing only on lower portion of wing where 

 it is not absorbed by the apical patch. Fringes checkered. Secondaries 

 rather uniformly pale smoky, with a faint reddish tinge. A moderate, dusky, 

 discal spot. An indication of a median stripe on inner margin. Terminal 

 line brown, sending small squarish spurs into the inner half of the fringe. 

 Beneath, evenly smoky on primaries in central and inner areas, remainder 

 yellow with brown strigations. The central fascia and subapical patch are 

 reflected, but not strongly. Secondaries whitish-yellow, finely strigate with 

 brown. A brown irregular cross-line best marked on costa extends two-thirds 

 across the wing outward of the middle. Occasionally this reappears on the 

 inner margin near the anal angle as a diffuse spot. A second, large con- 

 spicuous spot is on the center of the inner margin and tends rarely to unite 

 with the discal spot. 



Types. — Four males and three females, all in Dr. Barnes col- 

 lection except two cotypes, which are with the author. 



Habitat. — Redington and Santa Catalina Mts., Arizona. I have 

 before me also several other poor specimens which have not been 

 made cotypes. 



The species is not a typical Mesolcnca, but is referred here in the 

 absence of a more suitable genus. In structure it differs only in the 

 long palpi, which are slender and project far beyond the head. In 

 general appearances it differs considerably from the more typical 

 members of the genus. 

 2. Mesoleuca interrupta ochreata, new variety. 



This form, which at first glance appears very closely to resemble the 

 species to which I refer it as a variety, is seen on close observation to differ 

 from it in many points, which however I am inclined to regard as only 

 varietal. Aside from the bright yellow ground color of the primaries, which 

 contrasts strongly with the pure white of typical interrupta, the median fascia 

 is unbroken and less attenuated posteriorly ; the basal and intradiscal lines are 

 narrower and extend further out on the cubital vein making, in the case of
