100 IOWA STUDIES IN NATURAL HISTORY 



The primaries of nanno are more apically produced and the secondaries 

 relatively smaller and more rounded than in the normal species of Ambly- 

 scirtes. 



2. AMBLYSCIRTES ELISSA 



Amblyscirtes elissa G. & S., Biol. Cent.-Am., Rhop. II, 505, pi. 95, ff. 40, 



41, 1900. 

 Skinner, Ent. News XV, 344, 1904. 



I have not seen this species. Apparently it is very similar to nanno. 

 Skinner reports it from Cochise County, Arizona. 



3. AMBLYSCIRTES AENUS 



Amblyscirtes aenus Edw., Field and Forest in, 118, 1878. 

 Holland, Butterfly Book 341, pi. xlvii, f. 7, 1898. 

 Colorado, Texas, Arizona, New Mexico; May to July. 



4. AMBLYSCIRTES CASSUS 

 Amblyscirtes cassus Edw., Papilio in, 72, 1883. 



Amblyscirtes simius Wright, (not Edw.), Butt. W. Coast pi. XXXI, f. 454, 

 1905. 



Arizona; June, July and September. 



The under surface of the secondaries of cassus is heavily irrorate with 

 pale gray scales which give these wings a roughened appearance. The 

 spots are large and distinct but vaguely defined. 



5. AMBLYSCIRTES CELIA 



Amblyscirtes celia Skinner, Ent. News vi, 113, 1895. 



Texas, March, April and July. 



There is a specimen in the Barnes collection which has been compared 

 with the type, and from which I have noted that the under surface of the 

 secondaries is finely but rather sparsely and roughly powdered with gray; 

 6pots small but not clear-cut. 



6. AMBLYSCIRTES VIALIS 



Eesperia vialis Edw., Proc. Acad. Nat. Sci. Phil. 1862, 58, 1862.

 Holland, Butterfly Book 340, pi. xlvii, f. 5, 1898. 



United States and Southern Canada; May, June, July, August. 



7. AMBLYSCIRTES HEGON

Hesperia nemoris Edw., Proc. Ent. Soc Phil, n, 507, 1864. 



Scudder, Butt. New Eng. n, 1589, 1889. 



Holland, Butterfly Book 340, pi. xlvii, f. 6, 1898. 



Georgia north into Canada and west to central Iowa; May and June; 

 August in the north.
