spots. A row of termiual darker luuiiles. Orbicular indistinct, but 

 traceable, elongate, oblique. Reuiforoi large, upright, somewhat con- 

 stricted at middle, with a few white scales aloug outer margin. Sec- 

 ondaries smuky; fringes paler, more yellowish. Beneath blackish, 

 powdery; secondaries with distinct outer line and discal spot. Head 

 and thorax concolorous with primaries; tuftings distinct; yellowish. 



Expands 37 millimetres; 1.5 inches. 



Habitat. — Maine, Minnesota. 



The unique type is from Mr. Thaxter. The species is nearest to sputa- 

 trix, but is smaller, lacks the contrasting pale markings of reniform, and 

 has a black streak along inner margin near base. 



[Since the above has been in the hands of the printer, Dr. O. Lugger 

 has sent me a specimen for determination, taken at St. Anthony Park, 

 Minn. It agrees perfectly with the Maine specimen.] 



Group alticola. 



This group is established for a single species, rather aberrant in 

 habitus, but most nearly related to the devastatrix series, differing by 

 the lacii. of the spots preceding the s. t. line. Tue latter is even and 

 distinct. The claviform is wanting, there is no connecting dash, no 

 basal dash, and there are no contrasts in color througUout the wing. 

 Altogether the species is recognizable and easily distinguished. 



Xylophasia alticola Smith, sp. uov. 



Head and thorax ashen gray, with more blackish admixed scales. 

 Primaries paler, powdery, with an admixture of yellowish green, all the 

 maculation distinct. Basal line white, not definite. T. a. line black, 

 with a preceding white line, outwardly oblique to submedian interspace, 

 then with a broad inward tooth on internal vein. T. i). line nearly 

 parallel with outer margin, regularly dentate, black followed by a white 

 line. S. t. line white, sinuate, and small W mark at middle. An in- 

 terr.ipted blackish terminal line; fringes cut witli white. A vague, 

 dusky, median shade. Orbicular rounded, not defined, small, white. 

 Eeniform upright, moderate in size, white ringed, center concolorous. 

 Secondaries evenly fuscous, fringes white. Beneath pale, powdery, with 

 a common outer line and a discal spot on all wings. 



Expands 1.45 inches, 36 millimetres. 



Habitat.— Gibson Mountains, Colorado, 12,500 feet. 



A single male specimen collected by Mr. Bruce is before me. The 

 species differs prominently from all the described species, and has no 

 close allies in the genus. There is a vague suggestion of devastatrix 

 in the habitus, and perhaps to this species it may be most nearly related. 

 The greenish shade is not localized, but is rather more prominent in 

 the basal and s. t. spaces.
