88 IOWA STUDIES IN NATURAL HISTORY 



California, south into Mexico; May. 



Melane and the female of taxiles are similar but they are not difficult to 

 separate; usually the locality from which the specimens come is sufficient. 



7. P0ANE8 HOWARDI 

 Pamphila howardi Skinner, Can. Ent. xxviii, 187, 1896. 

 Phycanassa viator Holland, (not Edwards), Butterfly Book pi. xlvi, f. 14, 

 1898. Op. cit. pi. XLVI, f. 38. 

 Florida. 



The expanse of specimens which I have seen runs between thirty-two and 

 thirty-six millimeters. Aside from this and its darker color the species 

 does not differ superficially from aaroni. 



8. POANES AARONI 



Pamphila aaroni Skinner, Ent. News i, 6, 1890. 

 Holland, Butterfly Book 363, pi. xlvi, f. 37, 1898. 



New Jersey, June and August. I have seen specimens only from Angle- 

 sea and Atlantic City. 



Aaroni expands twenty-seven to thirty-three millimeters and is paler, 

 more yellowish, than howardi. Howardi may yet prove to be a southern 

 race of aaroni. 



9. POANES YEHL 

 Pamphila yehl Skinner, Ent. News iv, 212, 1893. 

 Holland, Butterfly Book 359, pi. xlvi, f. 40, 1898. 



Tennessee, Georgia, Mississippi; August and September. 



Superficially this species looks more like a relative of A. conspicua but 

 the mid tibiae are spined. The white spots on the under surface of the 

 secondaries in the female are unique. 



10. POANES RADIANS 



Eesperia rad,ians Lucas, Sagra's Hist. Cuba vii, 650, 1857. 

 Pamphila streckeri >Skinner, Ent. News iv, 211, 1893. 

 Skinner, Ent. News xxviii, 82, 1917. 

 Florida. 



The only specimen which I have seen is the type of streckeri and since 

 it lacks the middle legs it is impossible to place the species definitely. 

 Barnes and McDunnough place it in the genus Euphyes in the check list, 

 but without specimens at hand. Its superficial resemblance is rather with 

 aaroni. 



Genus ATRYTONE Scudder

 Euphyes Scud., Syst. Rev. 59, (80), 1872. Type Hesperia meta-
