beetles collected in the interior of the Labrador peninsula in 1894 by 

 A. P. Low/ I have combined these lists with my own. 



With the very kind permission of the authorities of the U. S. 

 National Museum, Dr. L. O. Howard and Mr. E. A. Schwarz, I am 

 also able to include Mr. Schwarz's manuscript list of the fifty-nine 

 species collected by L. M. Turner in 1883, in the Ungava Bay region 

 in northern Labrador. Some reference has been made to this collec- 

 tion by the late Roland Hayward in his " Studies in Amara." Mr. 

 Schwarz has very recently gone over his list for me, and has also 

 examined a number of the species received by me. 



Licluding these other lists I am now able to present a list of 166 

 species, of which 46 are Carabidje and 34 are Dytiscidse. In regard 

 to my own material, I wish to say that my good friend, Mr. Frederick 

 Blanchard, has examined and determined a large percentage of the 

 species, supplying at the same time copious information as to several 

 of them, so that to a great extent it is Mr. Blanchard's list rather 

 than my own. The late Roland Hayward examined nearly all the 

 species of Carabidje, Mr. C. H. Roberts has carefully studied the 

 Dytiscidse, and, as before stated, Mr. Schwarz has studied several of 

 my species. 



I have sought to indicate the geographical distribution of the 

 various species to some extent, including particularly records of occur- 

 rences in Greenland, the White Mountains of New Hampshire, 

 Alaska, Newfoundland, the Hudson Bay region. Some of the pub- 

 lished lists consulted for this purpose are: 



1. Coleoptera Groenlandica, by Wni. Lundbeck. ( Videnskabalige 

 Meddelelser, 1896.) This list enumerates 33 species, of which 9 

 occur in Labrador. One or two other species not listed by Lundbeck 

 occur both in Greenland and Labrador. 



2. List of the Coleoptera of Mt. Washington, by Fred. C. Bow- 

 ditch, Psyche, June, 1896. This list embraced the list of E. P. Austin 

 and other previous lists. 



3. Lists of Mt. Washington insects by Mrs. Slosson, published at 

 various times in Entomological News. 



4. List of Alaska Coleoptera, by John Hamilton in Transactions 

 American Entomological Society, Vol. XXI, January, 1894.
