Sept., igio.] A List of Labrador Coleoptera. 177 



6. Notiophilus semistriatus Say. 



Ungava Bay (Turner: Schwarz list). Mr. Schwarz writes, April, 

 1910: " The Notiophilus has in the meantime been determined accord- 

 ing to Fall's paper as scniisfriafiis Say." Fall cites Massachusetts, 

 Staten Island, Pennsylvania, New Jersey, Veta Pass, Colorado, Breck- 

 inridge. Colorado (9,600-10,000 feet), and Cloudcroft, New Mexico. 



7. Nebria sahlbergi Fisch. 



Sloop Harbor; Cape Chidley (Packard); interior of Labrador 

 (Low: Fletcher list); West St. Modest, common. Mt. Washington, 

 N. H. (Bowditch) ; Kenai and Sitkha. z\laska ; Queen Charlotte 

 Island, Vancouver, Lake Superior, Quebec (Hamilton) ; Nelson River 

 House, Hudson Bay (R. Bell); Newfoundland: southwestern coast 

 plain; Grand Codroy River, and Humber River (Bolster). 



8. Pelophila rudis Lee. 



9. Pelophila ulkei Horn. 



Both forms at West St. Modest. One specimen of rudis from 

 Cape Charles. Six specimens of ulkci from Red Bay. Fletcher lists 

 ulkei from the interior ; Schwarz lists it from Lhigava B^' ; Percy 

 Bolster took one specimen on the Humber River, Newfoundland. 

 Rudis. the form with the red markings, is apparently much less com- 

 mon than the entirely black ulkci. Both species were described from 

 the Hudson Bay region and both were taken by Dr. Bell. 



Dr. Van Dyke wrote me some time ago as follows : " The Pclo- 

 philas are mere color varieties of the same thing; ulkci and rudis 

 were based at the most upon very small series of boreal beetles which 

 we know vary much, not only in color, but also in physical charac- 

 ters." And again, after his trip to Alaska: " The series of Pelophila 

 from Labrador furnished several examples of what I was looking 

 for, that is specimens with the punctures in the stride well indicated. 

 This proves to me that they are simply offshoots of Pelophila Esch- 

 scholtzii Mannh., and really should not be more than subspecies. We 

 will need, however, to get material from more intermediate regions, 

 before passing final judgment. The Labrador specimens are all some- 

 what smaller than mine from Alaska." 



10. Bembidium longulum Lee. 



West St. Modest; one specimen sent to Hayward. Occurs in Lake 

 Superior region.
