HESPERIOIDEA OF AMERICA 77 



Pamphila nemorum Skinner (not Boisd.), Ent. News xi, pi. n, f. 21, 1900. 



Kellogg, Am. Ins. pi. IX, f. 21, 1904. 



Oberthiir, Etudes IX, (1), pi. coxl, f. 2087, 1913 (type). 



California, May to July. 



Edward's description states that milo has hyaline spots in the primaries 

 and agricola none; Oberthiir 's figure proves that they are present in the 

 type of agricola, hence milo is probably merely a synonym.

Type Hesperia mystic Edw. 

 Palpi upturned ; third joint about one-half as long as second, 

 slender, distinct. Antennae shorter than in Augiades, varying 

 from two-fifths as long as the primaries in some females to one- 

 half in some males; club rather large, usually longer in the 

 female and occasionally almost as long as the shaft; apiculus 

 abruptly constricted and reflexed, shorter than thickness of club 

 though variable in length. Wings variable; costa of primaries 

 usually straight except at base and apex but sometimes slightly 

 emarginate or convex; outer margin very slightly sinuate to 

 evenly rounded, more rounded in the female. Primaries often 

 apically produced in the male, less so in the female. Second- 

 aries broadly rounded, very slightly lobed at the anal angle. 

 Cell of primaries about three-fifths as long as wing ; vein 5 much
