﻿March 1895. CaLVERT. OdONATA OF NeW YoRK S'lATE. 41 



I found them to differ considerably from "locality i ", ist, in the 

 much greater abundance of the form marked No. 31 \^Hetcerina 

 americana], and 2nd, in the absence of many forms found in 

 locality i, especially of the larger forms as No. 14 \^Libellula 

 pulchelld\. The difference, I imagine, was chiefly, if not entirely, 

 due to the presence in locality i of the clay-holes. Had my 

 health been better than it was this summer, and the weather 

 less intensely hot, I might have visited a number of other localities, 

 and obtained, I think, a better collection. One thing that struck 

 me rather forcibly was the fact that in the summer of 1893, when 



I was around the brook to some extent for other purposes, a large 

 dragonfly with body of a brilliant metallic green was very numer- 

 ous and conspicuous along the whole length at least of locality i, 

 while this year, with the exception of a single specimen which I 

 think I saw one day when outdriving, they were absolutely lacking 

 wherever I went. iVnother thing that I noticed is that the larger 

 dragonflies seldom make their appearance as early in the morning 

 as the smaller forms, these latter being quite numerous between 9 

 and 10 of a bright morning, while the big ones, or at least those 

 marked 12 and 14 \Lihelliihi piilchella\, seldom appeared until near 



II in the part where I was collecting. I was unable to procure 

 any immature forms". 



The list of species derived from all the sources above men- 

 tioned comprises 85, if not 86, species. The aim has been to give 

 the precise locality in each case. Where this is not possible, and 

 merely the State can be quoted, the place of original record has 

 been given. Species not previously mentioned as from this State 

 in the above cited papers, or in the catalogues of American 

 Odonata of Hagen 1875 and of Banks 1893, are marked by an 

 asterisk (*). The arrangement of the species is the same as in 

 the writer's Catalogue of the Odonata of the vicinity of Philadel- 

 phia (Trans. Am. Ent. Soc. xx, pp. 219 — 272, 1893), in which the 

 majority of the following species are described.

One male, Keeseville, June 9, 1894. "Seemed very rare. The 

 only specimen I obtained was picked out of the grass by the brook, 

 in a limp condition, when the grass was wet. I nevei again saw 

 this form, except a few times in June, flying about the grounds of
