Forest one or two females in A\hich \ariation had taken 

 place along exactly opposite lines. In these the abdomen 

 was either entirely bronze or very nearly so. Their 

 identity was at first not easily made out. De Selys 

 mentions ("Revue," p. iSi; that Mr. Dale took varieties 

 of a similar kind to the last in Dorsetshire.

Date. 



This is one of the summer Dragonflies, appearing on 

 the wing just before the middle of June. Thence it 

 continues to fly for about three months. The earliest 

 date on which I have seen it is June 9, and the latest 

 September 21. . 



Habits. 



Slender, delicate form and feeble flight seem to be 

 the most prominent characters of Pyrrhosouia tcnclliini. 

 It often rests on the rushes and taller grasses round 

 the margin of the ponds, and so on, that constitute its 

 haunt. As it is usually jjlentiful where it occurs, it 

 sometimes rises in large numbers when its habitat is 

 invaded.
