394 THE CANADIAN ENTOMOLOGIST. 



On the morning of January 31, 1912, I followed the log-filled 

 stream back of the rest house at Rockstone, British Guiana, for 

 a mile or two. On two occasions I saw for an instant a large 

 brilliant green and golden-brown aeschnine which cut across the 

 stream, with only a moment's hesitation above the water. About 

 1 p.m. my father and I were at the stream, when we saw it again, 

 but this time flying a beat, possibly 75 or 100 feet long. It dis- 

 appeared over the trees as I approached, and we decided it was 

 some glorified Afiax to be found at home possibly at some neigh- 

 bouring pond. The next day father and Mr. Rainey made a 

 search for such a pond, while I again collected on the creek. Their 

 search for a pond was in vain, but they found the home of our shy 

 acquaintance of the day before in a small shallow muddy creek 

 bed, in the woods, and Vv^ithout running water, there being merely 

 pools of greater or less extent. 



They saw several specimens, got several fair strokes at the 

 dragonflies and afhrmed that in striking from the rear at the dragon- 

 liies they were unable to make the net overtake the insect. The 

 next day I visited this creek bed just below the town on the same 

 side of the river. Never have I seen a dragonfly apparently more 

 out of place — the little muddy wet-weather creek, in some places 

 with the jungle crowding it to a scant 2-foot width, with its obscure, 

 leaf-filtered sunlight on dry or damp mud banks and isolated pools 

 of dirty water — and back and forth in this narrow avenue, from 

 shade into sunlight and back into shade again, a great green and 

 golden aschnine which so clearly belonged to the sunny reaches 

 of marsh or lake. After a few futile strokes I caught one, and then 

 another, and Staurophlehia does not take its capture tamely or 

 philosophically. They fought, tearing and biting, and attacked 

 the fingers which drew them from the net. 



Staurophlehias were seen only rarely elsewhere in British 

 Guiana, and then only along smaller streams. None were seen 

 the two days I collected in Dutch Guiana. On March 7, 1912, Mr. 

 Rainey and I were accompanied by Mr. F. W. Urich to Baracon, 

 Chaquanas, Trinidad. We found the woods near there very dry 

 with the stream beds in many cases without any water. Along 

 such a stream bed we found a dark bluish or greenish dragonfly 

 flying. Till specimens were captured it never occurred to me that
