TRIFID&. 1 85 



of the most interesting results of their journey was the 

 finding of this pretty species in abundance among the sweet 

 gale and other herbage on the bogs about Tore cascade, 

 Mucross, and Dinas Island ; the wettest bogs appearing 

 to be the most to its taste. In 1877 two specimens were 

 taken at Wicken Fen, Cambridge, by Mr. A. B. Farn, and 

 the next year two more by Mr. W. H. B. Fletcher, but it 

 was not till 1882 that the metropolis of the insect in that 

 county was discovered a few miles from Wicken Fen, at 

 Chippenham Fen, by Mr. W. Warren. Here it is taken 

 every year by those who have permission to collect in the 

 fen. It may also be still found in varying numbers in the 

 Killarney district by those who undertake the journey, and 

 has been observed in other places in Kerry, but I know of 

 no other localities for it in the United Kingdom. Abroad it 

 has a wide distribution, through Central Europe, Northern 

 Italy, Livonia, Northern and Eastern Turkey, Southern 

 Russia, Armenia, Persia, Tartary, China, and the Altai 

 mountain districts.
