12 Journal New York Entomological Society. [Vol. xxi. 



Also in this Journal for September, 1898, appeared a " Preliminary 

 List of the Dragonflies of Staten Island, with notes and Dates of 

 Capture," by the present author. The information contained in these 

 publications, together with the last edition of the New Jersey list, and 

 much unrecorded material gathered in recent years has formed the 

 basis of the present list, which numbers one hundred and seventeen 

 species. The author has personally taken all but seven of the species 

 at localities here recorded. He has been presented with four of the 

 others by their captors ; has examined two in collections, leaving but 

 one species to be added from the literature alone. Only four records 

 have been taken from Dr. Calvert's New York lists, as most of his 

 material came from localities further up the state. Following these 

 and other copied records, the collector's name is given in parenthesis. 



The New Jersey list enumerates one hundred and nine species and 

 the present list will add nine, including a new species, to the number 

 known to occur in that state, all but three belonging to the Agrionidae. 

 Several species are also added to the New York list. Ischnura 

 kellicotti has, according to the New Jersey list, been found in Ocean 

 and Atlantic counties, but it will certainly be collected nearer to New 

 York City than at present recorded. 



To Prof. Raymond C. Osburn I am indebted for the suggestion 

 that I prepare the present list to include the species taken at localities 

 within about fifty miles of New York City, and also for much help in 

 connection with the new species. Mr. Lewis B. Woodruff has kindly 

 given me a list of his captures, many of which were made in West- 

 chester Co., N. Y. ; Mr. George P. Engelhardt, of the Children's 

 Museum of the Brooklyn Institute of Arts and Sciences, has let me go 

 over his material, and Mr. Frank E. Watson has added to my col- 

 lestion from time to time such species as attracted his attention while 

 in quest of butterflies. This information, together with one or two 

 other records from friends, is in each case followed by the name of 

 the contributor. When no name is given the records have been 

 taken from material in the author's collection. 



In the matter of classification the recent " Catalogue of the 

 Odonata of North America," by Richard A. Muttkowski, has been 

 followed.
