Correction: Among- the material collected by the Museum Expedition 
in Vilas Co., Wis., June 24-30, 1907, I found upon comparison one male Tetra- 
(jonciDia spinosa Hag-en. This record, added to the three other species of 
Tctragoneuria known from Wisconsin, completes the series of Northern species 
of Tctragoneuria for the state. T. spinosa is known from few localities and 
these chiefly Eastern. The occurrence of this species both in the White Mts. 
of N. Hampshire and in Northern Wisconsin is but another instance of the 
noted resemblance of the fauna of these two widely separate localities. (Bull.
