Sept., 1910. 1 A List of Labrador Coleoptera. 185 



64. Agabus congener Payk. 



Very common. West St. Modest, Red Bay, Cape Charles, Hope- 

 dale, Nachvak, Fort Chimo. Common in White Mountains, above 

 the tree line, in September. '' An arctic, alpine, and subalpine spe- 

 cies " (Sharp). Greenland, Siberia, Sweden, Finland, Lapland, 

 Britain, Germany, France, northern Italy (Sharp). 



65. Agabus inscriptus Crotch. 



Described from Labrador. I have a few specimens from West 

 St. Modest and Red Bay. 



It is less common than congener with which it is united by Sharp. 

 Crotch's inscriptus is a smaller form, less reticulate and more shin- 

 ing, more convex in form, and the color tends more to yellowish 

 and red; while the congener form is darker, more opaque, and more 

 depressed. Inscriptus is moderately common at Hermit Lake, Mt. 

 Washington, N. H. (3,700 feet), but is seldom found above the tree 

 line. Inscriptus Crotch is probably the beetle referred to as discolor 

 Lee. by Packard in his list, from Indian Harbor. 



66. Agabus nigripalpis Sahib. (:^ borcalis Sharp ^= dissimilis Sahib.) 



Stupart's Bay (R. Bell), several. This is the species listed by 

 Packard as Agabus longidus Lee. ? Regarded by Sharp as probably a 

 variety of congener Payk. My single specimen, one of the Bell 

 specimens presented to me by Mr. W. H. Harrington, is a narrow 

 elongate beetle, with the sides very parallel, much smaller than any 

 of my own Labrador allied specimens and quite different in appear- 

 ance. This same form also taken at Cape Digges by Dr. Belli. 



67. Agabus infuscatus Aube. 



Ungava Bay (Turner: Schwarz list). Very common West St. 

 Modest, Hopedale. Either this species or inscriptus Crotch is un- 

 doubtedly the beetle from Caribou Island listed by Packard as am- 

 biguus Lee. This Labrador species is the real infuscatus of Aube, 

 as I know from typical specimens received from Rene Oberthiir. 



Whether the beetle taken by Mr. Bowditch in Lakes of Clouds, 

 Mt. Washington, N. H., in July, is the same as this Labrador species 

 I do not know, but all the specimens of i)ifuscatus Aube I have ever 

 seen are from Labrador.
