ly. Oeneis chryxiis Dbldy. & Hew.— ^ Mackinac ;' May 27- 

 June 12. Occurs in considerable numbers on the sand dunes 

 near Manistique in early spring. 



Nymphalidae 



18. Argynnis cybcle Fabr. — Schoolcraft, Mackinac, Emmet, 

 Charlevoix, Marquette; June 24-August 11. Common. The 

 females show great variation in color, running from very dark 

 specimens to those as light as the specimens taken in the Por- 

 cupine Mountains. 



19. Argynnis aphrodite Fabr. — Schoolcraft, Mackinac, 

 Emmet, Charlevoix, Marquette; July 8- August 11. Normally 

 not quite so common as cybele, but in 192 1 it was almost the 

 only Argynnid seen. All of the specimens approach the form 

 cypris Edw. 



20. Argynnis atlantis Edw. — Schoolcraft, Mackinac, Mar- 

 quette, Gogebic; June 20-September 10. Common, at times 

 very abundant. I have seen bushes actually bending beneath 

 the weight of thousands of these butterflies. 



21. Brent his myrina Cram. — Schoolcraft, Mackinac, Char- 

 levoix, Cheboygan, Gogebic ; May 28- August 20. Common. 



22. Bretiithis bellona Fabr. — Schoolcraft, Mackinac, Charle- 

 voix, Gogebic ; May 28- August 20. Not so common as myrina. 



23. Etiphydryas phaeton. Dru. — Mackinac ; June 20-30. 

 Taken only in one locality, where four specimens were found 

 in each of two years. 



24. Phyciodes nycteis Dbldy. & Hew. — Schoolcraft, Mack- 

 inac; June 8- July 16. Common. 



25. Phyciodes tharos Dru. — Schoolcraft, Mackinac, Emmet, 

 Charlevoix; June 7-September 8. Abundant. Both the form 

 morpheus Fabr. and the form marcia Edw. occur, apparently 

 simultaneously, and every gradation between these forms may 

 be found.
