June, 1914] Rehx-Hebard: Dermaptera from Florida. 97 



The series here treated comprises six hundred and eight specimens 

 of one hundred and four species, one of which has proved to be new. 

 Many of the records here given are of particular interest as the range 

 of a number of species is extended by the same, while quite a few 

 of the forms represented are but little known and scarce, both in col- 

 lections and in nature. In addition to this collection a small series of 

 twenty-two specimens, collected by Dr. J. Chester Bradley in the same 

 region, is recorded in this paper. 



The authors wish to thank Mr. Davis for his courtesy in permit- 

 ting them to examine the material here treated, and also for allowing 

 a representation to be retained for the collections of the Academy of 

 Natural Sciences of Philadelphia and the Hebard Collection. 



Throughout the present paper the notes in quotation marks have 

 been inserted by the collector, Mr. Davis.
