larger than that of the following race. The northern limit of macularia 

 we do not know but apparently it is somewhere about the longitude of 

 Winnipeg, Man. as the type specimen of agyllaria Wlk., to which we 

 have already referred, was taken at St. Martin's Falls, Albany River. 



Agyllaria Wlk., to our mind, represents at least a good race and if 

 the differences in the $ genitalia (PI. XXXI, Fig. 4) be borne in 

 mind may possibly prove to be a good species; its range seems to be 

 from Hudson Bay westward to the Rockies and down these with 

 slight modifications into Colorado; we have specimens from Calgary, 

 Alta. (PI. XXVII, Figs. 3, 4) which agree well with the type; besides 

 the differences already noted we would point out that there is a distinct 

 tendency for the t. p. line on underside of secondaries (and at times 

 even on upper side) to become geminate much as in certain Euchlaena 

 species ; there is also on the basal side of the t. a. line of primaries on 

 the inner margin a distinct ruddy or purplish spot usually present 

 which in the nimotypical form is scarcely ever found in the S sex. 



In the Great Basin Region (Utah, Nevada) agyllaria merges into 

 crocearia Pack. (PI. XXVII, Fig. 9) in which the terminal suffusion 

 is salmon-color and extends almost to apex, the spot on inner margin 

 behind the t. a. line quite pronounced and the basal portion of secon- 

 daries whitish. On Vancouver Is., B. C. a very similar form is found 

 (PI. XXVII, Figs. 4, 5) in some ways intermediate between agyllaria 

 and crocearia with less sexual dimorphism than in either form ; we do 

 not think however that there are sufficient grounds for proposing a 

 name for this form, at least for the present. 



In the Southern portion of California we meet with two races 

 which differ widely from each other and also from the described 

 forms ; the one race occurs in the San Bernardino Mts., is rather small 

 in size, averaging 24 mm. from tip to tip, of a pale yellow color, slightly 

 lighter than in macularia but with the terminal suffusion heavy, pur- 

 plish and sharply defined apically in both sexes by vein 4; the basal 

 portion of costa is strongly purplish, the t. a. line usually faint but 

 with a well-defined blotch on inner margin, the t. p. line forms a small 

 V at apical portion of costa, the concave portion of outer margin 

 below apex is distinctly shaded with deep purple ; on the under-side of 

 secondaries the t. p. line is broken up into dots with little or no ruddy 

 terminal shading, although this is quite well defined on upper side ; the 

 fringes are generally strongly checkered on primaries and at anal angle 

 of secondaries (especially in $ ) they are tinged with purplish; in the
