NOTES ON THE NEUROPTERA OF 

 ROTHIEMURCHUS AND KINGUSSIE. 



BY JAMES J. F. X. KING. 



[Read 27th April, 18SG.] 



In the spring of last year I fixed upon the neigh- 

 bourhood of Insh as my summer holiday resort, 

 with the view of increasing my knowledge of the 

 Neuropterous Fauna of the Rothiemurchus and 

 Kingussie districts. I had previously spent vacations 

 at Kingussie and Loch-an-Eilan, in the years 1875, 

 1877, and 1878, where I accumulated a considerable 

 amount of material which I wished to supplement 

 by collecting in fresh pastures and at a later period 

 of the year. Altogether, I have spent about fifteen 

 weeks in these districts, and visited a ULimber of 

 outlying localities which have produced many 

 interesting species. 



The conditions of the country are very favourable 

 for the production of Neuroptera, there being no 

 scarcity of lochs, rivers, burns, and marshes, at 

 various levels from 700 to upwards of 3000 feet. 



The Spey is of course the most important 

 river that passes throLigh these districts. In the 

 neighbourhood of Kingussie, as well as near Avie- 

 more, the bottom is gravelly, and river species of 

 Caddis-flies occur in abundance ; while near Insh 

 the bottom is muddy, and these insects are therefore 

 scarcely represented. The rivers next in importance 

 are the Feshie and the Tromie, which run over a 

 gravelly bottom throughout the greater jDart of 

 their courses. 



Loch Morlich, situated at the base of Cairngorm 

 on the north-west side, at an elevation of about 

 1046 feet above sea-level, is over a mile in length 

 by about five-eighths of a mile in breadth. It
