13. Atheta graminicola Gravh. 



Gravh., Mon. Col. Micropt. (1806), p. 76. 



Stonolota granulata Mann., Bull. Mosc, XIX (1846), 

 p. 508. 



Three specimens. This small rove beetle is abundant on Un- 

 alaska and Atka islands, and is also to be found on the Alaska 

 Peninsula, Kodiak, Queen Charlotte Islands, as well as in Arctic 

 Europe and Asia. 



14. Quedius fulvicollis Steph. 



Steph., 111. Brit. Ent, V (1832), p. 244. 



Hyperboreus Er., Gen. (1839), p. 547. 



Not found by Dr. Hanna, but secured previously by Professor 

 Kincaid. It is found also on Unalaska Island, at Nome, and 

 extends across the continent to Labrador and Newfoundland, 

 to Maine, to Colorado, to Vancouver Island, and is found like- 

 wise throughout Europe and Arctic Asia. 



15. Tachinus apterus Maklin 



Maklin, Bull. Mosc, XXVI (1853), p. 113. 



Six specimens from St. George Island. This species is sup- 

 posed to be restricted to this island, but though considered distinct 

 by Fauvel, is undoubtedly very closely related to others found 

 at Unalaska and on the mainland. 



16. Arpedium beringenus Van Dyke, new species 



Apterous; nigro piceous, antennae, palpi, margins of the 

 prothorax and elytra, and feet refuescent. Head triangular, vertex 

 bi-impressed, front slightly convex and shallowly obliquely im- 

 pressed on each side anteriorly, the disc alutaceous and minutely 

 sparsely punctate, the tempora very prominent, the head rather 

 suddenly constricted behind. Antennae extending almost to 

 middle of elytra, joints 2, 3 and 4 of about equal length and 

 breadth, slightly more than twice as long as broad, 4 — 10 gradually 

 shorter and broader but never broader than long or transverse. 

 Prothorax transverse, one-third broader than long, slightly nar- 

 rowed posteriorly, moderately convex, broadly shallowly emar- 

 ginate at apex, narrowly emarginate at middle of base, sides
