COLEOPTERA FROM THE PRIBILOF ISLANDS, 



ALASKA

The collection of Coleoptera, made by Dr. Hanna while 

 stationed on the Pribilof Islands during the summer of 1920 con- 

 tains 21 species, most of them represented by numerous specimens. 

 It includes nearly all of those known to have been found there. 

 In the present report, the lacking ones are mentioned in order 

 to make the list as complete as possible. A short bibliography is 

 also given. 



The beetles of the Fur-seal Islands are better known than 

 is any other portion of its insect fauna, many of the species having 

 been known for a long time. The first one to be mentioned was 

 Carabns truncaticollis Esch., which was captured by Dr. Esch- 

 scholtz while on his second voyage, the second Kotzebue Expe- 

 dition, 1823-1826, and described in 1833 in his "Zoological Atlas." 

 Eschscholtz does not seem to have visited the Pribilofs during his 

 first voyage, 1815-1818, although he collected on Unalaska Island 

 on that trip and not only described a number of the species 

 captured, in his "Entomographien," published in 1822, but fur- 

 nished Fisher von Waldheim with a number to be described by 

 him in his "Entomographia imperii russici," published in 1820- 

 1822. Other species named by Eschscholtz were not described 

 by him because of his early death, but by others, such as Count 

 Dejean and Baron von Mannerheim who, of course, are given 

 credit for the same. Meanwhile, other Russians stationed at the 

 Fur-seal Islands, as elsewhere in the Russian possessions in 

 North America, collected specimens and sent them back, chiefly 

 to the two great museums at Moscow and St. Petersburg. Here 

 they were described by various workers, chiefly Menetries at St. 

 Petersburg and Count von Mannerheim at Moscow. The latter, 

 in his classical "Beitrag zur Kafer-Fauna der Aleutischen Inseln, 

 der Insel Sitkha and Neu-Californiens," published in 1843 in the 

 "Bull, de la Soc. Imper. des Natural, de Moscou," and in his three 

 supplements to the same, published respectively in 1846, 1852, and 

 1853, gave us the most complete work which has been published
