ruptata; we figure the type 9 as well as a specimen of pemotata 

 for comparison. 



Mesoleuca gratulata latialbata var. nov. (PI. XXII, Fig. 11). 



Typical gratulata (PI. XXII, Fig. 10) has the median white band 

 strongly constricted centrally below the cell due to an outward bulge 

 in the dark basal area and a strong inward bend below vein 4 of the 

 outer dark area. In three $ specimens before us from Plumas Co., 

 Calif, this median white band is of much more even width throughout; 

 the basal area forms only a slight projection below the cell and the 

 outer bounding line is bent in far less than in the typical form, being 

 quite far removed from the bases of both veins 2 and 3. Our speci- 

 mens being all absolutely constant in this respect we believe that we are 

 dealing with a good racial form for which we propose the name 

 latialbata. We figure specimens of both forms for comparison. 



Epirrhoe plebeculata vivida var. nov. (PI. XX, Figs. 1, 2). 



After a careful reading of Guenee's description there is little 

 doubt in our minds that plebeculata, based on a single $ from Cali- 

 fornia, is the same species as that described later by Packard from a 

 single 9 from Nevada as rubrosuffusata although it is quite probably 

 that Packard's name may be held for a racial form with redder secon- 

 daries. According to the description the secondaries of plebeculata 

 are pale yellow; in a bred series from Alameda Co., Calif. (PI. XX, 

 Fig. 3, 4) before us the color varies from pale dull yellow to dull 

 brick color, the general effect of the whole coloration of the wings 

 being dull and faded. In specimens from Vancouver Is., B. C. the 

 coloration is much more vivid and contrasted, the tint of the secondaries 

 being a bright orange-yellow with generally rather well-defined macu- 

 lation ; for this northern race we propose the name of vivida and have 

 made 4 $ 's and 2 9 's from Wellington and Goldstream B. C. types, 

 a pair of which we figure. 



Zenophleps obscurata infumata var. nov. (PI. XIX, Fig. 11). 



Typical obscurata (PI. XIX, Fig. 10) was described from material 

 from Siskiyou Co., Calif, and is found throughout the Sierras at mod- 

 erate altitudes ; it is characterized by pale yellow subterminal and ter- 

 minal shading. In Arizona we meet with a race which is much darker 

 in color, the cross bands being deeper brown and the terminal area 

 suffused with smoky with only traces of the yellow tints of the nimo-
