Vol. XI] HANNA— PRIBILOF ISLANDS INSECTS 155 



In 1911, Dr. Barton W. Evermann, then Chief of the Alaska 

 Fisheries Service, directed the intensive collecting of specimens 

 in all branches of natural history, having in mind ultimately, a 

 complete monograph of the group. Naturalists were appointed 

 and as assistants they had the services of the resident school 

 teachers. Thus, A. G. Whitney, on St. Paul, 1912-14, and the 

 writer on St. George, 1913-14, made considerable collections of 

 insects which were promptly transmitted to the Government. A 

 report upon them, however, has not as yet appeared. 



With the departure of Dr. Evermann from the Bureau 

 of Fisheries, his policies were unfortunately changed and it was 

 not until the summer of 1920 that insect collecting again engaged 

 the attention of the writer. Some opportunity was then presente 

 to obtain a fair series in most of the groups. It is this material 

 which forms the basis of the following report. In addition to 

 the material listed the collection contained several species o\ 

 Diptera and Hymenoptera which are still undetermined. 



In the report of 1899, 42 species were listed. The number 

 reported herewith is 86. Together the two reports contain about 

 100 species. Those which have been listed or described in other 

 places bring the total up to about 125 species exclusive of the 

 Hymenoptera. Of this order Ashmead 3 lists from the Pribilofs 

 67 species, of which 52 were described as new to science . 



Schwartz 4 estimated that the total number of insects which 

 might be expected there would be about 400 species. If cor- 

 rect, it appears that the work is not as yet half done. 



The 1899 report contains erroneous statements, quoted from 

 Elliott 5 , which need correction. On page 550 "a very few 

 species of butterflies" are recorded. There are no butterflies 

 on the Pribilofs. Likewise the record of "a single dragon fly" 

 on page 552 should be ignored, because these insects are absent. 

 Similar sweeping statements were made regarding several species 

 of mollusks in his "Monograph." 



The absence of mosquitoes and other insects injurious to man 

 and animals is noteworthy. The Pribilof tundra is a paradise to 

 one accustomed to similar territory in other northern regions.
