reduced to a narrow dull gray band preceded by a dotted blackish 

 line, the whole basal area being deep smoky ; the outer band is less 

 intensely black and narrower. Beneath there is none of the prom- 

 inent black marginal banding of anartalis, both wings being pale whitish 

 ochrcous with slightly darker terminal area ; the primaries show small 

 orbicular and reniform marks and there is a trace of a dotted post- 

 median line crossing both wings ; the fringes are pale smoky basally, 

 whitish outwardly and there is a broken dark terminal line to both 

 wings. The coloration of the upper side of primaries is rather vari- 

 able, being deep smoky-black more or less shaded and suffused with 

 white scaling giving a grayish appearance basally and subterminally ; 

 the maculation is similar to that of anurtalis but the orbicular and 

 reniform are smaller and generally better defined and the median area 

 often considerably darker than the rest of the wing. We regard this 

 form as specifically distinct from anartalis and propose the name 

 ALBERTALis for the species ; our type $ is without a label but probably 

 from the same locality as our 9 type which was taken at Gleichen, 

 Alta. (July) by Mr. Wolley-Dod; we have other specimens from 

 Beulah and Miniota, Manitoba, and a single Alaskan $ which pre- 

 sumably belongs here but which has the whole basal half of secondaries 

 much paler. 



In Utah we meet with another form (PI. XXII, Fig. 16) in which 

 the secondaries are entirely blackish with a trace of a pale s. t. band 

 confined to the central portion of the wing and quite improminent. 

 Beneath both wings are much darker than in albcrtalis, being gray 

 quite heavily sprinkled with smoky, the maculation being otherwise 

 as in this species. The primaries above are quite similar to those of 

 albcrtalis but slightly darker in tone. For this form we propose 

 the name saxicolalis, our type being a $ from Stockton, Utah 

 (May) ; besides this specimen we have four other worn ones taken at 

 Eureka, Utah, in April and May. 



LoxosTEGE TERPNALis sp. nov. (PI. XXII, Fig. 20). 



Palpi, head and thorax clothed with mixed black and white scales ; pri- 

 maries with a general dark bluish-gray appearance caused by heavy white 

 scaling over a blackish ground color, shaded with white broadly before t. a. 

 line and beyond t. p. line as well as along outer margin except at apex ; t. a. 

 line rather regularly outcurved; t. p. line arising from slight blotch on costa, 

 squarely exserted around the cell and finely crenulate with a prominent tooth 

 above vein 1 ; some apical dark shading continued as a fine line across wing
