154 ENTOMOLOGICAL NEWS [April, '12 



there is one pool where the water is possibly 2 feet deep. 

 The banks are grass-grown or bare in places, with much 

 willow herb and some lizard tail. The water is warmed by 

 its exposure in fields, and is fouled by barnyards and the 

 visits of domestic animals. 



On July 2, 1911, en route to Little River, I reached the 

 bridge over Flat Creek on the Wells-Huntington Counties 

 line at about 8 A. M., and leaving the motorcycle on the 

 bridge, started up the creek through the Simmers woodlot. 

 At a short distance I saw a dragonfly, hovering like a 

 Tetragonenria, over a ripple. It left the ripple, flying up- 

 ward and being lost to sight. It appeared again at the rip- 

 ple, not approaching by following the creek, but "dropping 

 down from the clouds ;" and it disappeared as it had in the 

 first instance. After a few moments' wait I followed the 

 creek through the woods to the fields beyond without see-

 were seen. Leaving the creek I went to Little River near 

 Mardenis where I expected to find Macromias, and where 

 I hoped, after my experience at Flat Creek, I might find 

 Somatochloras. Collecting here without success and think- 

 ing over the morning's experience, I became more and more 

 convinced that the first Somatochlora seen was a different 

 species from the one captured. The first one seen showed 

 no yellow at all in the two good views I had of it, while 

 the one captured gave me a distinct glimpse of yellow, 

 though I had but the most fleeting glance at it on the wing. 

 So before noon I returned to Flat Creek, first a mile below 

 where I had collected in the morning, and later at the former 

 woods. But at neither place did I see any Somatochloras. 



The next day, Monday, I made a hurried early morning 

 trip to the creek in the Simmers' woods, and saw the, Soma- 

 tochlora again, a good view and one that convinced me it
