also abound. The climate may be said to be one of extremes ; 

 the summers are usually hot and the winters often severe. An 

 idea of the extremes can be gained when it is stated that in 

 July, 1911, the Government weather bureau recorded a tem- 

 perature of 107 degrees, and in January, 1912, 27 degrees be- 

 low zero a range of 134 degrees within 6 months. The aver- 

 age annual precipitation is about 31 inches, by far the greater 

 part falling between April and August. High winds are com- 

 mon and many an otherwise perfect day is utterly spoiled for 

 butterfly collecting by a stiff wind, causing butterflies to hide 

 in shelter. 



The writer has spent five years collecting in this locality, 

 and as he does not find that anything has been written con- 

 cerning the butterflies to be found here he gives the following 

 list as embracing the species found on the Nebraska side of 

 the river in the immediate vicinity of Omaha. 



The classification used is that found in Dyar's List of N. A. 

 Lepidoptera (Bull. 52, U. S. Nat. Museum), and reference 

 was had to the following works in arriving at identifications : 

 The Butterflies of North America. W. H. Edwards. But- 

 terflies of the Eastern U. S. and Can. S. H. Scudder. The 

 Butterfly Book. W. J. Holland. Everyday Butterflies. S. 

 H. Scudder. The Butterflies of the West Coast. W. G. 

 Wright. The Butterflies of Montana. M. J. Elrod. A Re- 

 view of the Hesperiidae of the U. S. H. G. Dyar. The Boreal 

 Am. Species of Chlorippe. Hy. Skinner. Entomological 

 News, Canadian Entomologist, and original descriptions of 

 species from various publications. 



Access was also had to the collection of the University of 

 Nebraska and to the private collection of Dr. Robt. H. Wol- 

 cott, of Lincoln, Neb., the latter also kindly assisting in mak- 

 ing identifications.
