NEVROPTERA AND TRICSOPTERA OBSERVED TN THE LAKE 



DISTRICT. 



BY KEKNETH J. MORTON, F.E.S. 



A short visit to the Lake District in the first half of last 

 September, was much too late in the season to enable one to obtain 

 anything like a representative sample of its Neuropterous fauna, and 

 it is superfluous to add that a worse year could hardly have been 

 selected for collecting in an area which, even at its best, is a wet one. 

 Notwithstanding these drawbacks, a very considerable amount of 

 material was broiight together, and as not too much has yet been put 

 on record with regard to the Netiroptera of this grand district for 

 water insects, I propose to give here a complete list of our captures. 



By far the greater part of our collecting was done about Coniston 

 Lake, but we ranged on cycles, as far north as Keswick and Ullswater. 

 The distances to be covered on the longer excursions precluded us 

 from doing much collecting either at our destination or on the way 

 out and back. I am satisfied if one had ample time, a very interes- 

 ting series of comparative observations could be made by assiduously 

 collecting the Trichoptera found at the various lakes. 



The most interesting species taken was MesopJiylax impunctatus, 

 an insect still imperfectly known in its type form, as a British insect, 

 from a single ^ taken by Service in Dumfriesshire, the Shetland
