G6 STATE BOARD OF AGRICULTURE. 



It has been proposed to cultivate some of the species for the purpose of 

 reducing the mosquito pest ; but this left out of consideration the fact that 

 dragon flies are active during the bright sunshine when the mosquito does not 

 fly unless disturbed, while at night, when the mosquito is most active, the 

 dragon fly is at rest. 



Dr. Philip P. Calvert, of the University of Pennsylvania, has made a special 

 study of this family and has courteously determined and arranged the New 

 Jersey material. He should be credited with the following list in its entirety, 

 and writes as follows in explanation. 



ORDER ODONATA. 



BY PHIUP P. CALVERT. 



At Prof. Smith's request I have undertaken to prepare the list of insects of 

 this order hitherto found in New Jersey. In doing so, I have included only 

 those species of which I have seen specimens from the State, or for which only 

 the best authority (Dr. Hagen or Baron de Selys) exists. The material upon 

 which this list is based has been collected or furnished by the following 

 gentlemen, for whose courtesy and aid I here return thanks : Messrs. S. F. 

 Aaron, N. Banks, W. Beutenmuller, W. T. Davis, G. M Greene, S. F. Gross,' 

 H. Hornig, C. W. Johnson, S. T. Kemp, P. Laurent, P. Nell, L. Riederer, C. F. 

 Seiss, H. Skinner, J. B. Smith, H. V. Viereck, H. W. Wenzel. Most of the 

 records by Mr. Crane, of Caldwell, from the first edition of this catalogue have 

 also been included, together with my own record (C), and data on some speci- 

 mens in the collection of the Academy of Natural Sciences of Philadelphia 

 (A. N. S. ). The abbreviations in parentheses are used as in the other portions 

 of the list to indicate the source of information for each locality cited. 



The localties under each specific name are arranged in geographical order 

 from north to south. Mr. Davis' list of the species of Staten Island has been 

 included foi obvious reasons. The arrangement of the species is the same as 

 that of my " Catalogue of the Odonata of the Vicinity of Philadelphia " (1893), 

 in which most of those following are described. The total number is here 

 given as 90, but additional search will no doubt increase it to beyond 100.
