P. campestris Behr. 



This species and pratensis Behr, both described in the same paper 

 (Proc. Cal. Acad. Sci. Ill, 86) have generally been considered as 

 referring to the 9 and $ respectively of one species, although Behr 

 apparently had both sexes of each and gives the habitat of the for- 

 mer as "marshy places where Hemitonia abounds" (presumably in 

 the vicinity of San Francisco Bay) and of the latter "grassy hillsides" 

 around San Francisco. A careful comparison of his descriptions with 

 numerous specimens before us fails to show any definite points of dis- 

 tinction and we concur for the present with the synonymy as gen- 

 erally adopted. We would point out however that campestris has 

 "line" priority over pratensis and if the two names do actually refer 

 to a single species this should be designated as campestris Behr. It is 

 a matter we will have to leave to our Californian lepidopterists to 

 determine whether the marsh form and the hill-side form show any 

 material points of distinction. Wright's Fig. 201 as well as his figures 

 202, 202b, and 202c (as orseis) are all campestris (pratensis) ; his 

 figure 201b should probably be referred to pallida Edw. 



P. camillus Edw. 



Emissa Edw. is at present listed as a variety of this species but 

 apparently is only the 9 and should fall into the synonymy. The 

 types on which both names were founded were taken in Colorado by 

 Mr. Mead. The species is probably merely the Rocky mountain form 

 of the California campestris Behr; in fact specimens from Northern 

 B. C, Idaho, and Washington before us could as well be referred to 

 the one name as the other. 



The other two names, pallida Edw. and mata Reak., at present 

 placed as forms of camillus, presumably on the authority of Edwards' 

 Catalogue, we treat as forms of mylitta Edw. for reasons stated below. 



P. orseis Edw. 



This was described from Mt. St. Helena, Napa Co., Calif., and 

 is stated to be the largest of the Californian species. It is at present 

 doubtfully listed as a form of pratensis Behr. We have two speci- 

 mens from Sonoma Co. which we have identified as this species from 

 a comparison with the types in the Hy. Edwards' Collection ; we be- 

 lieve it will prove to be a good species ; besides its larger size, it is 

 very heavily black on the upper side, the fore wing is distinctly emarg- 

 inate below the apex and the scallops of the outer edge of secondaries
