Distribution. 



This northern and Alpine Dragonfl}' has at present 

 been recorded in the British Isles onh' from the Ran- 

 noch and Breadalbane districts of Perthshire. Previous 

 to 1865 its claim to a place in the British fauna rested 

 on a single specimen taken in the north of Scotland by 

 Mr. Wilson, and by him given to De Sei}'s, as stated 

 in the " Rexue des Odonates," p. 121. In the beginning 

 of June, 1865, however, Mr. McLachlan took two males 

 and a female fl\'ing over steep and rock}' banks near 

 Camachgouran, on the south of Loch Rannoch. In the 

 Black Wood and on the north side of the loch during 

 the \\eek ending June 22, 1889, Messrs. Morton and 

 King took two males and three females ; while in June, 

 1895, the former was fortunate enough to discoxer a 

 more southerl}- localit}' in the Breadalbane district, and 

 there to capture several specimens. It is probabh- 

 present in the intervening countr\- between these two 

 districts, and perhaps in other localities also. It is 

 satisfactory to note that the species at Rannoch, in 

 i8g8, on the occasion of a special \isit b)- ^Messrs. King., 

 Porritt, Briggs, and Morton, between June 7 and 21, was 

 common during the second half of the period."^
