terminal line. A yellow and then a black line on fringes, beyond which they are 

 gray, cut with brown. Beneath uniform smoky brown. 

 Expands, I.00-I.16 inches = 25-29 mm. 



Habitat. — Santa Rita Mts., Arizona, 5,000-8,000 feet, in June; 

 F. H. Snow. 



Two males and two females in good condition from Prof. Snow. 

 The species is allied to clientis in the position of the black apical 

 spot ; but it is smaller, the vestiture is rough, the maculation much 

 more obvious and diffuse, the s. t. line on secondaries is much more 

 prominent and courses of all the lines differ obviously when compared. 

 The smaller size, rougher vestiture and more conspicuous markings 

 are the easily recognizable features. 



EASTERN AND CENTRAL EUPITHECIAS. 



Richard F. Pearsall,

With our Eupithecias, especially the eastern forms, there has here- 

 tofore been no systematic attempt to separate the species. In an effort 

 to do so my first aim was to gather material in large quantity and to 

 separate it into species, regardless of name. Following this the appli- 

 cation of names of described species to some of the forms required 

 long study and patient discrimation, and while some problems remain 

 unsolved, the long series of commoner forms in my own collection 

 serve to establish these names beyond any doubt in my own mind. 

 Even the elusive miserulata has been ferreted out by this method. The 

 result leaves a number of forms, which cannot be included under the 

 old names, and some of them are described in this paper ; others still 

 remain in abeyance, represented by single examples whose status will 

 not be clear until better specimens are at hand. 

 Eupithecia mutata, new species. 



Expanse 19 mm. Palpi long, rather heavy, dark brownish, tipped with white. 

 Antennae in $ flattened, strongly ciliate, in 9 flattened, almost simple. Head and 

 thorax dark brownish gray. Wings whitish leaden, shaded withdark gray or dark brown 

 and rust-red scales, the latter forming a band across fore wings, within basal area, 

 which is frequently wanting or replaced by a leaden gray band, and another, always 

 present with more or less distinctness just outside extradiscal geminate pale line. 

 Basal line fine, of black scales, near to origin of wing, turning sharply outward at
