Among- the insects collected by Dr. G. Dallas Hanna on the 

 Pribilof Islands in 1920 are several which belong- to the orders 

 mentioned above. The Lepidoptera are of special interest since 

 no species of this order has heretofore been recorded from these 

 islands. The Neuroptera listed below were determined by Mr. 

 Nathan Banks and the Lepidoptera by Messrs Barnes and 

 Lindsey.
