32 THE ASIATIC FUR-SEAL ISLANDS. 



then numbered 37 species. Of these, no less than 12 species belong to the Staphy- 

 linidcB. The other orders are represented by 2 species of Hemiptera, 5 Biptera, 3 

 Eymenoptera, 2 of which are new and thus far only known from the Commander 

 Islands, viz, Mesoleius stejriegeri Ashm., and Stibeutes nigrita Ashm., 1 Siphonaptera, 

 and 2 Lepidoptera, viz, Agrotiphila alaskce Grote, and a Macroglossa near stetiarum 

 Linn. 



It should be remarked that the insects collected of late years in the neighborhood 

 of the main villages must not be given too great weight in determining the zoological 

 relationship of the islands, for many have undoubtedly been introduced recently from 

 Petropaulski, Kamchatka, in the large quantity of firewood shipped to the islands 

 every year. In fact, some of the species collected by me in 1895 were taken on or 

 near the wood pile. 



In 1897 my wife and I made additional collections of insects both on Bering and 

 Copper Islands. Mr. Barrett- Hamilton also collected quite a number, which, with 

 characteristic generosity, he placed at my disposal to be presented to the United States 

 National Museum. These collections are now being worked up, and a report on the 

 insects thus far recorded from the Commander Islands is published in the appendix of 

 the present volume. 



MYBIAPODS. 



The three species brought home by me have been determined by Bollman. Idno- 

 tcenia cMonophila and LithoMus sulcipes, both from Bering Island, are known from 

 other localities, but the species described by him as new, under the name of LithoMus 

 stejnegeri, is the only one thus far found only on the Commander Islands (Bull. U. S. 

 Nat. Mus. No. 4=6, 1893, p. 199). 



ACAKIDS. 



The acarids collected by the Vega expedition have been described by Kramer and 

 Neuman (Vega Exp. Vet. lakt., iii, 1883, pp. 619-532, pis. xli-xliv). No less than 

 5 new species were described from Bering Island, 4 of which were found only on the 

 latter, as follows: Nesma arotica, Bdella villosa, Ixodes borealis, I. fimbriatus, and 

 Qamasus arctieus. Of these I obtained all but J. fimbriatus, and obtained iive 

 additional species, four of which are new. 



SPIDERS. 



It was my intention to get as nearly complete a collection of spiders as possible 

 and in l882-'83 I succeeded in obtaining quite a number of species, which were turned 

 over to the United States National Museum. They were lent to the late Dr. Marx 

 to be determined, but the report was not finished before his death. The spiders 

 collected during 1897 have been worked up by Mr. Nathan Banks (in appendix), 



CRUSTACEANS. 



The crustaceans collected have not been worked up as yet, except the entomos- 

 traca, which have been described by Prof. W. Lilljeborg, of Upsala, Sweden (On the 

 Entomostraca collected by Mr. Leonhard Stejneger, on Bering Island, 1882-83. Proc. 

 U. S, Nat. Mus,, X, 1887, pp. 154-156). Pive species were collected, of which I found
