authentic. Notwithstandiiig the name, the legs ai-e ferru- 
ginous in color, precisely as called for by the description. 
The Labrador examples which LeConte refers here, as well 
as the Lake Superior specimens which he designates as a race 
of the present species, are all opacus Sahlberg. 
27. Gyrinus lugens LeConte 
Form rather broad, though somewliat variable; moderately iieai'ly ^:^ym- 
metrieally convex; black, sides more or less bronzed; rather strongly shining 
but with a fine reticnlato-alutaceons sculpture which is a little more evident 
in the female; minute punctulation sparse or nearly wanting in the male, 
generally more detectable in the female. Strial punctures moderate, not 
very noticeably larger in the outer rows, which are not appreciably impressed. 
Beneath metallic black, legs rufous, anal segment often more or less so, but 
frequently nearly or quite concolorous. 
Male genitdlia. — Piceous, middle lobe laterally compressed apically where 
it becomes very narrow from a vertical view j)oint, but ai)i)reciubly wider 
as .seen from the side. 
Length, .a. 1.7 to l).7 mm.; width, 2.7 to .‘kb mm. 
Ti/pe local ill/ — Artissachust'tts.

diffu.scil Gyrinus in New England, and aitpcars to ])e fairly 
al)undant throughout the greater })art of its range, which ex- 
tends westward to ^Manitoba. I have not seen it from farther 
south than New Jersey and Pennsylvania. The following spe- 
cific localities have been noted: Little Liver, Southwest New- 
foundland (Bolster), 1 9, identity tolerably certain: Maine

LeConte says of this species “not at all bronzc'd abovi*.’’ 
This is only true of exceptional sj^ecimens and does not even 
(piite apply to his type, wdiich has one side' margin hu'bly nar- 
rowly bronzed, the other not at all so. In the genei'al run of
