A LIST OY NEUEOPTEEA COLLECTED IN THE ISLAND of GUEENSEY. 



BY W. A. LUFF. 



The following list of Guernsey Neurojptera will probably be found 

 capable of considerable augmentation, as there still remain certain 

 streams and ponds which I have not yet searched for this Order of 

 insects. The places I have mostly worked are the small rapid streams 

 on the south coast, and a considerable extent of marshy land on the 

 west coast, near Yazon Bay, called " La Grande Mare." This last is 

 being, however, rapidly drained, the ponds are already filled in, and 

 before many years elapse, this happy hunting ground of the botanist 

 and entomologist will be changed into cultivated fields, or covered with 

 glass houses for the production of grapes and tomatoes. 



My best thanks are due to Mr. McLachlan for his kindness in 

 examining and naming most of the specimens. He has added a few 

 species not yet noticed by me, collected by himself in September, 1891 

 (c/ ante pp. 5—6), and by Mr. F. V. Theobald in 1890. These are 

 included in brackets. 



My list includes a few species taken in Guernsey many years ago 

 by the late Dr. Mauger.
