practically complete, except for its colouring. The 

 specimen was a female. During the whole time the 

 imago had not moved forward up the stick, but at the 

 end of the metamorphosis was hanging immediately 

 above the head of the nymph-case. In another instance, 

 the rest lasted for twent)^ minutes, but the process of 

 emergence was very similar, and the time occupied 

 much the same. 



Date. 



In early seasons P. nyiitplinla appears in April, the 

 earliest date noted being April 29, when, in 1894, large 

 numbers were out on Esher Common, in Surrey ; but in 

 average seasons it begins to emerge in early May. It is 

 at its best in June, but may be taken through July, 

 and even lingers till the beginning of August. 



Habits. 



This Dragonfly seems to like to make its haunt near 

 ditches, streams, canals, &c., where vegetation is luxuriant. 

 Here amongst the herbage and about the bushes it is 

 often abundant. 



Distribution, 



There is no doubt that this species is well distributed 

 and common throughout the British Isles, but, probably 

 on account of this ver)- fact, the recorded localities are 

 by no means numerous. Iiivcnicss-shifc : Strathgiass
