BUTTERFLIES OF MONTANA. IX 



Preface. 



In preparing some Nature Study work for teachers it became appar- 

 ent that teachers have little to work on in this region to enable them 

 to prepare studies on butterflies. It was really to assist teachers and 

 others in identifying specimens that this bulletin wa? prepared. It is 

 hoped that it will meet the needs of teachers and be of material assistance 

 to them. The boys and girls of the state have little to assist them in 

 the study of natural history specimens of the state, since the books which 

 would be serviceable are either too expensice or too volumnious to handle. 

 If the study of the butterflies is stimulated in the coming generation the 

 writer will feel amply repaid. 



Full credit for most of the assistance rendered has been given in the 

 Introduction. Mrs. C. A. Wiley, of Miles City, has very kindly placed at 

 our disposal a copy of Edwards' Butterflies of North America, with icolored 

 plates. Supt. P. M. Silloway of Lewistown, has rendered material aid 

 in collecting specimens at Swan lake. The glossary has been prepared 

 by Josiah J. Moore, of Anaconda, a student at the University of Montana. 

 The index nas largely been prepared by my wife. 



I offer no apology for making some of the descriptions much longer 

 than others. Some of these are totally inaccessible to hundreds of those 

 who will use this work. A lengthy description of a species that will be 

 difficult of determination will be of great service to the young student. 

 Where the specific characters are easy of determination and good photo- 

 graphs are supplied the descriptions are brief. 



After the matter was all in type a list of butterflies was received from 

 Prof. Ezra Allen, of the State Normal at Dillon, which specimens have 

 been incorporated in the work. The information in this bulletin includes 

 reference to specimens collected in the eastern end of the state at Miles 

 City, the central portion at Bozeman, the southern part at Aldridge and 

 Dillon, the main Rocky Mountain region at Helena, the western slope at 

 Missoula and Flathead Lake.
