This species is the most nearly alHed to P. comma of all American species ; the size of 

 the two is the same, and the upper surface of the females vary in each species to the same 

 extent ; there are no constant featvires of distinction in the upper surface of the male, al- 

 though in P. Manltoha the hind \yings are usually devoid of the appearance of the spots on 

 the under surface, which generally are faintly but exactly marked upon the upper surface 

 in the European species. The under surfaces of the two species also resemble each other 

 closely, and it is a little difficult to define in words the distinctions which are apparent ; 

 the ground color inclines more to deep green in P. comma, and the mesial bent band of 

 the hind wings is rather more uniform ; in the male it seldom departs from a certain regu- 

 larity of disposition, the spots being nearly equal, arranged in a line bent at a little less 

 than a right angle, occasionally broken into spots, and sometimes with a narrow black bor- 

 dering to the spots upon the inner and outer side. In the male of P. Manitoha, the spots 

 generally diminish in size toward the middle of the wing, and from the greater approxima- 

 tion to the outer border (shown by the spot in the interspace beyond tlie cell), the band is 

 bent at considerably less than a right angle ; the spots are never bordered with black, at 

 least in specimens I have seen. The female of P. comma agrees ver}^ well with the male 

 of the same in its characteristics, only the band is somewhat broader, and perhaps more 

 frequently made up of detached spots, while the female of P. Manitoha difters to a greater 

 degree from its male, the spots showing greater tendency to become equal in size, to sep- 

 arate from each other, and even to become margined slightly with black; it is therefore 

 less readily distinguished from the same sex of P. comma than the males are ; there is 

 also great variation in the breadth of the band or the size of the spots, for while usually 

 larger than in the male (as in most species) they are sometimes many times larger, and 

 occasionally almost as small as in the most delicately marked males. Upper organ bent at 

 a riglit angle in the middle, and romnled ; sulcated above, as in P. comma ; the hook and 

 lateral arms closely resemble those of P. comma, but are shghtly shorter, the hook only 

 about one-fourth the length of the centrum. Clasps a very little more than twice as long 

 as broad, closely resembling those of P. comma ; the posterior border is, however, smoothly 

 rounded, and not so protuljeraiit ; the teeth are of equal length, similarly incurved, and 

 very narrowly separated by a very deep rounded excision ; the lamina supporting the inner 

 anterior edge of the tooth is very shght, having but one or two dentations and then dis- 

 appearmg. 



It is a wide-spread species, having been taken in Colorado by Mr. Mead, about Pike's 

 Peak (Edwards), on the shores of Lake Winnipeg, by the late Mr. Kennicott and myself, 

 by the late Mr. Crotch at Labache, and at Riviere du Loup l)y Mr. Coujier.
