hover over the Httle stagnant pools. Nynaphs were first found in small 

 holes in the almost dry marsh land, too small to allow the use of a net 

 and containing but a few inches of water. A larger number was obtained 

 later from debris deposited in the marsh during high water and still sub- 

 merged a few inches. Removed from the water the nymph clings closely 

 to the debris of exactly its own color, and does not stir even after letting 

 this dry ; so it is very hard to see and a difficult subject for collection.

The females oviposit in the shallow places where the nymphs live, in 

 temporary water of one to two inches depth, and very warm. The 

 female dips the tip of her abdomen to the surface after the manner of all 

 Libellulines, but only about three or four times ; then rests; then repeats. 

 The eggs are creamy white turning dark in a short time, and with 

 scanty gelatinous envelop. (From the account by Mr Weith)
