Mr Evans has one of the finest private collections in the State, and 

 has taken several species in Vanderburgh County, which have not been 

 taken elsewhere within our limits, among them the large and beautiful 

 Argynnu diana. Mr. Worthington has collected extensively in Lake 

 County, where many rare species occur, and his list and notes have 

 added materially to the value of the catalogue. To the above named 

 gentlemen, as well as to a number of others from whom information was 

 derived, which is duly acknowledged in the proper places, my especial 

 thanks are due. 



It will be seen that the counties mentioned, in addition to those of 

 Gibson, Randolph and Fayette, from which lists have been received, 

 represent fairly well all portions of the State ; yet twenty-three addi- 

 tional species are given in Mr. Edward's Catalogue of the Butterflies of 

 North America, whose range includes or approaches Indiana, but which, 

 as far as known, have not been taken within our limits, and, therefore, 

 are not included in the present catalogue. Moreover, ihe known distri- 

 bution within the State of a number of the species taken is much more 

 limited than it should be ; hence additions to the catalogue, as well as 

 information with regard to extension of range within the State, are 

 earnestly requested and will be duly acknowledged. 



To make the catalogue as valuable as possible to future collectors, not 

 only has the known range of each species within the State been given, 

 but also its favorite place of resort and the season at which it is most 

 abundant, together with any other information regarding variation or 

 habits which it was thought would be of interest. Prof. G. H. French 

 in his manual of "The Butterflies of the Eastern United States," has 

 treated of the habits of the larvae of most of the species, but has said but 

 little about the habits of the mature insects. To the student of Indiana 

 butterflies this catalogue will perhaps serve as an accessory to French's 

 work, and hence little or nothing is said of the larvae. 



The nomenclature adopted is that of Edward's "Revised Catalogue 

 of the Diurnal Lepidoptera of America North of Mexico," published in 

 the Transactions of the American Entomological Society for 1884. The 

 number in parenthesis before each name is that of the species in the 

 catalogue cited. 



Finally, I have thought it best to include the synonymy of each of 

 the species which is treated of in the works which the student of Indiana 

 butterflies will be most likely to possess and to which I have had access 

 in preparing the eatalogue. Those works are the following : 



Edwards, W. H. "Butterflies of North America." Volumes I 

 and II. 



French, G. H." Lepidoptera, or Butterflies and Moths," in the. 

 Seventh Report of the State Entomologist of Illinois, 1878. The But- 

 terflies of the Eastern United States, 1886.
