DISTRIBUTION OF COLP:OPTERA. 101 



69. Ilybius ater DeG., ungularis Lee. 



This species is probably rare here, as I know of no one who has 

 taken it. Middle States (Pennsylvania;, LeConte. Europe (the 

 mountainous parts and north to 63° 40' in Finland). West Siberia.

70. I. subseneus Er. 



(Hudson Bay ; Canada) ^de Sharj). Europe (Germany ; France 

 to 69°). Arctic Siberia (northern tributaries of the Jenisei). Sh., 

 552 ; Heyden, 57.

Widely distributed, but infrequently recognized. Labrador, 

 Hudson Bay region 54° to 65°. Canada, northern Michigan, Lake 

 Superior, Kansas, Alaska. Germany. Sweden. Finland to 69°.

 64"^ in Finland. Southeastern west Siberia. Sh., 556 ; Heyden, 57. 



73. Agabus {Gaurodytes) congener Payh.. ambiguus Say, dhcolor Harris (T. 

 X, "278), var. lapponicns Sahib. 



Thus constructed the range of this species is Pennsylvania, Massa- 

 chusetts, Labrador (Caribou Island, Packard), Greenland, Hudson

 species," Sharj). 



74. A. dissimilis .<?rt7i?6., f long ulus Ijec. 



Specimens of this species were so determined by Dr. Shai-p for 

 Dr. Horn, although in his Dytiscidse (p. 513) he is not quite certain 

 of the distinctness of the s])ecies from congener Payk. Should the 

 two species prove identical the distribution would be Europe ; Si- 

 beria ; Hudson Bay ; Greenland ; Labrador ; and Lake Superior. 

 Stupart's Bay, Hudson Straits, Harrington.
