It appears from Roesel's figure that the larva of P. grandis 

 forms a case of the outside sheaths of the base of Reeds or 

 some such aquatic plants. DeGeer found the eggs in a double 

 mass of jelly deposited on Sallow leaves which hung over a 

 stream ; and Mr. Hyndman of Belfast has seen the female 

 P, grandis enter the water for that purpose, which is so re- 

 markable a fact that I shall transcribe his remarks on the sub- 

 ject, which he was so obliging as to communicate to me. 

 " Tfie Phryganea was taken at the Botanic Garden, Belfast, 

 the 27th May, 1833. I first observed it on the leaf of an 

 aquatic plant, from which it crept down along the stem, under 

 the water, very nearly a foot deep. It then appeared to have 

 been disturbed by some Sticklebacks which approached it and 

 seemed inclined to attack it, and swam vigorously and rapidly 

 beneath the water over to some other plants. I then took the 

 insect up and found a large bundle of eggs of a green colour 

 closely enveloped in a strong jelly-like substance, attached to 

 the extremity of its abdomen. The bundle of eggs was of an 

 oblong form, bent in the middle, and the two ends attached 

 to the tail of the animal."
