Enallagma. 297 



Distribution. 



The onh' known habitat of this species in the British 

 Isles is tlie New Forest, in Hampshire. Here in two 

 or three centres connected with the Lymington river 

 it ma}- be found, and at least in one of them rather 

 commonl}\ In this last locality the insect seems 

 luckil\- to have a strong hold, and consequently 

 there is little fear of its extermination in the 

 near future. If strict search were made it would 

 probably be found in fresh spots in the Forest, and 

 perhaps in other parts of the South of England and 

 Ireland also. On the wing, A. incrcurialc closely 

 resembles A. pnlcliclluin, A. piiclla, and A. cyatJiigcnim, 

 its near relatives, and perhaps this resemblance may 

 sometimes cause it to be passed over unnoticed. 

 Mr. C. W. Dale has in his collection specimens from 

 Glanvilles W'ootton, in Dorset, and from Winchester, 

 but the localit}- at the former place has now been 

 drained, and that at the latter is no longer known.
