took a teneral female Somatochlora in Fountain County, 

 which Dr. Calvert, several years ago, determined as linearis. 

 Along Flat Creek in Wells County, on July 2, 1911, I took 

 a male S. charadraea, and two days later, at the same loca- 

 tion, took a male of ,S. linearis. These are the State records, 

 scanty because of the nature of the dragonflies themselves, 

 but especially because no one is employed, or has the leisure, 

 to give the subject attention. 



The capture of no other known species could have fur- 

 nished a greater surprise than charadraea. The only other 

 specimen known was taken at an altitude of about 8,000 

 feet in Bear Creek Canon, Jefferson County, Colorado, by 

 Ernest J. Oslar. The elevation of Flat Creek is about 800 

 feet, and its name is indicative of its character, which is 

 anything but that of a mountain torrent. Flat Creek is a 

 tributary of Little River which it joins just above Mardenis, 

 Huntington County. Little River, meeting the Wabash 

 River at Huntington, is the shrunken descendant of the Fort 

 Wayne outlet of the extinct Lake Maumee whose waters 

 once passed into the Wabash. Flat Creek passes into Hunt- 

 ington County from Wells County about one and one-half 

 miles south of the Allen County line. Its last*2oo-3Oo yards 

 in Wells County is through brushy and rank second-growth 

 woodland on the Simmers sisters' farm. In Huntington 

 County it passes into a large open field, and above the Sim- 

 mers woodlot it runs for nearly a mile through practically 

 open fields and through the barnyard of the J. M. Settle- 

 meyer farm. Mr. Settlemeyer has made some borings in 

 the creek bottom on his farm obtaining a limited but con- 

 tinuous artesian water supply. He tells me that prior to 

 these borings the creek dried up in summer. Early in Inly. 

 1911, when I collected there, it averaged possibly 3 feet in 

 width and carried a very small amount of water. The creek 

 bottom will average about 3 feet below the land surface in 

 the adjoining woodland. Its course is meandering, and in 

 a few places there are perceptible ripples over gravel bot- 

 tom. The water is generally only a few inches deep, but
