Apparently very rare. It is remarkable that this conspicuous Dragon-fly 

 has not been observed in Ireland during recent years. Both Haliday and 

 De Selys were aware that it had been taken by Miss Ball ; but they did not 

 record the locality. Fortunately the place and date of capture are mentioned 

 by Miss Ball in her annotated copy of Stephens' " Catalogue of British 

 Insects" (1829), now in the possession of the Irish National Museum. An 

 Irish specimen, possibly the one recorded by Miss Ball, is preserved in the 

 Trinity College Museum. Mr. Lucas remarks that this species passes a great 

 deal of its time at a distance from water, and, in consequence, probably often 

 escapes observation.

This is the only species of Libellula found commonly in Ireland. We 

 have no records of the occurrence of migratory swarms of this insect in 

 Ireland, such as have been observed on the Continent and even in Great 

 Britain. The variety /xYicni/ti/rt, Newman, with a brownish suffusion of the 

 wings surrounduig the stigma spot, and saffron- coloured costa, occurs in 

 Ireland. 



Distribution. — Great Britain (Devonshire to Inverness, and the Hebrides). 

 Extremely widely distributed throughout the Palaearctic region, from Lapland 

 (rare) to Spain ; Kashmir {Calvert) ; Kamtschatka, and Alaska. Found also 

 in North America (Massachusetts and Colorado).
