in the fen. It is found about large tufts of grass growing 

 on dry ground in that district, never upon wet ground." In 

 addition to Yaxley Fen, Whittlesea Mere, Holme Fen and 

 Whittlesford, all in Huntingdonshire or Cambridgeshire, are 

 recorded as old localities ; and it is said to have occurred in 

 Wicken Fen, though this is strenuously denied by those who 

 are best acquainted with that locality. 



From these early captures the older collections were 

 supplied. Within the last few years it has been redis- 

 covered in Huntingdonshire, but, as already stated, no 

 information is obtainable, except that considerable numbers 

 have been secured. A record of the occurrence of the species 

 in Suffolk proved to be erroneous, and beyond those enume- 

 rated I know of no localities for it in the United Kingdom. 

 Abroad it is also extremely local, but seems to have been 

 taken in Central, Southern and Western Germany, Austria 

 and Hungary.
