80 IOWA STUDIES IN NATURAL HISTORY 



2. POLITE 8 MANATAAQUA 



Hesperia cern-es Harris, (not Boisd.), Ins. Inj. Veg., 3rd ed., 316, 1862. 

 Hesperia manataaqua Scudder, Proc. Ess. Inst, ill, 175, 1863. 

 Scudder, Butt. New Eng. n, 1720, 1889. 

 Holland, Butterfly Book 357, pi. xlvi, f. 30, 1898. 



Northeastern United States west into Nebraska and South Dakota; June 

 and July. 



Holland's figure looks like a dark female of taumas. Manataaqua is 

 readily distinguished from taumas in the female sex by its darker color, 

 paler maculation and larger size, though the difference is difficult to explain 

 in a key. 



2a. race EHENA 

 Pamphila rhena Edw., Field and Forest in, 115, 1878. 

 PampMla alcina Skinner, Ent. News IV, 212, 1893. 

 Skinner, Ent. News xi, 414, pi. n, f. 25, 1900 (type of alcina). 

 Kellogg, Am. Ins. pi. ix, f. 25, 1904 (type of alcina). 



Although retained for many years as a species this is apparently only the 

 western race of manataaqua. It is distinguished from the typical form by 

 its paler color, more extensive markings and the larger amount of pale 

 tawny or yellow fulvous which marks the upper surface. Colorado. 



3. POLITE S TAUMAS 



Papilio taumas Fab., Mant. Ins. n, 84, 1787. 



Hesperia thaumas Fab. (not Hufn.), Ent. Syst. in, (i), 327, 1793. 



Hesperia phocion Fab., Ent. Syst., Supp. 431, 1798. 



Hesperia cernes Bd. & Lee, Lep. Am. Sept. pi. 76, ff. 1, 2, 1833. 



Hesperia ahaton Harris, Ins. Inj. Veg. 3rd ed., 317, f. 140, 1862. 



Butler, Cat, Fab. Diurn. Lep. B. M., 277, pi. 2, f. 14; pi. 3, f. 9, 1869. 



Scudder, Butt. New Eng. n, 1725, 1889. 



Holland, Butterfly Book 357, pi. xlvii, f. 20, 1898. 



United States and Canada, April to August. 



I see no reason to doubt that Fabricius ' name applies to this species. 



4. POLITES BARACOA 



Hesperia baracoa Lucas, Sagra's Hist. Cuba vn, 650, 1857. 

 Pamphila amadis H.-S., Corr.-Blatt Begensb. xvn, 142, 1863. 

 Pamphila myus French, Can. Ent. xvn, 33, 1885. 



Florida, February to April, July, September. I have seen one record of 

 its occurrence at Toronto, Canada (A List of Butterflies taken at Toronto, 

 Gibson, Ont. Nat. Sci. Bull. No. 6, 1910, 35-44. Baracoa det, Skinner) but 

 the only specimens which I have seen came from Florida. 



The species is smaller and darker than taumas and the males are easily 

 distinguished by the small stigma. Some females of taumas run very 

 close, but in most specimens of baracoa the powdery spots mentioned in 

 the key are present.
