Anax loyigipes Hagen. June 2, 1898, one of this species was 

 flying over Glen Lake in Spring Grove. I watched it for two 

 hours, and though it came within a few feet of me, I was un- 

 able to catch it. It was a very large specimen, the abdomen 

 bright brick red, thorax and eyes green. June 3, I went 

 again to this lake, but did not see it until I moved down to 

 Linden Lake, nearly adjoining, when I again saw it, but failed 

 to catch it. Its flight is steady and in regular beats up and 

 down the middle of the lake, seldom coming near shore. I 

 made careful search during June, 1899, but did not see any at 

 these lakes.
