NEUROPTEROID INSECTS OF THE 

 EXPEDITION 



BY NATHAN BANKS 



The Neuropteroid insects collected by Professor Kincaid on 

 the Harriman Alaska Expedition represent thirty-four species. 

 They may be tabulated as follows : 



Pseudoneuroptera u 



Perlida? 9 



Ephemeridie 2 



Neuroptera x 



Hemerobiidae J 



Trichoptera 22 



Phryganeidse * 



Limnephilidse *6 



Leptoceridre 3 



Rhyacophilida? 3 



Total 34 34 



It will thus be seen that the great majority of the species be- 

 long to two families, Perlidae and Limnephilidae. As regards the 

 affinities of the fauna we can deal with only the described species, 

 twenty-five in number. These may be tabulated as follows :
