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 n 



Perlidse 9 



Ephemerida? 2 



Neuroptera I 



Hemerobiidse I 



Trichoptera 22 



Phrvganeidre I 



Limnephilidse 16 



Leptoceridse 3 



Rhyacophilidse 2 



Total 34 34 



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

 long to two families, Perlidce and Limnephilidag. 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 : 



Known from Washington State 10 



Known from Colorado 4 



Known from Europe 2 



Known from Northern United States 6 



Known from British America 2 



Known from Alaska only 8
