270 PEESH-WATEE AQUAEIA. 



throTigh tMs curious tail, and the creature is tlius able to 

 breathe atmospberic air wbile lying at the bottom of very 

 shallow water. When the larva is about to enter the nymphal 

 state, it buries itself in the ground, and becomes a pupa 

 while still within its larval envelope. The perfect insect 

 may be often seen flying about gardens and the like. It is 

 a httle more than 4in. long, is black and hairy, and is 

 very active in its movements. 



There are, of course, many other aquatic larvae and pupse, 

 besides those I have mentioned in this chapter, which are 

 suitable for and very interesting in the aquarium; but I 

 hope I have said sufB.cient to give a novice in aquarium 

 matters some idea what kind of creatures to look for, and 

 how to keep them in a manner satisfactory both to the captor 

 and the captives when found.
