 Immigrant Records for 1920. 



BY THE EDITOR. 



During- the year 1920, thirteen immigrant insects were re- 

 corded for the first time. A few of them were probably quite 

 recent arrivals, but for the most part they have been known 

 here for a number of years without having been determined 

 or recorded. One species, AiuniopJwrus iiisularis, was recorded 

 from Honolulu in 1858, but had not been seen since. It escaped 

 mention in the Fauna Hawaiiensis. It has now been re- 

 discovered. 



A list is here given with the pages on which records occur, 

 and notes in regard to habits, etc.
