HESPERIOIDEA OF AMERICA 101 



Hegon is more commonly known as samoset. It is similar to nereus but 

 the transverse row of spots on the primaries is usually less complete and 

 fresh specimens are much more greenish below. The distribution is suffi- 

 cient to separate specimens which bear locality labels.

9. AMBLYSCIRTES ALTERNATA

 Hesperia eos Edwards, Trans. Am. Ent. Soc. in, 276, 1871. 

 Amblyscirtes meridionalis Dyar, Jn. N. Y. Ent. Soc. xni, 135, 1905. 



Georgia; Skinner lists cos from Texas, Georgia and Florida. 



A specimen which Dr. McDunnough placed as altemata in the Barnes 

 collection proved to be the same as Dyar's types of meridionalis in the 

 Strecker collection, and the descriptions of all of the species lead me to 

 believe that they are synonyms. The primaries are apically produced, so 

 that the outer margin is longer than in vialis, and the fringes are an un- 

 usually pure white, as in nysa. The under surface has a transverse row of 

 faint, powdery spots on the secondaries and is otherwise similar to vialis. 



10. AMBLYSCIRTES NYSA 



Amblyscirtes nysa Edw., Can. Ent. ix, 191, 1877. 

 Pamplitta similis Strecker, Lep. Rhop. & Het. 131, 1878. 



Texas and Arizona, March to June. 



The under surface of the secondaries is distinctive and the fringes are a 

 clearer white than in any other species than altemata. The upper surface 

 of nysa is very similar to that of altemata in all particulars. 



11. AMBLYSCIRTES COMUS 



Hesperia comus Edw., Trans. Am. Ent. Soc. v, 206, 1876. 

 Amblyscirtes nilus Edw., Field and Forest III, 118, 1878. 

 Pamphila quinquemacula Skinner, Ent. News xxn, 413, 1911. 

 Biol. Cent.-Am., Rhop. II, 502, pi. 95, ff. 25, 26, 1900. 



Texas and Arizona, August. 



From a specimen in the Barnes collection compared with Edward's mate- 

 rial I have noted that the under surface is finely and smoothly grayish 

 irrorate and the spots small, white, sharply denned and not crowded to- 

 gether.
