In the Canadian Entomologist for March, 1899, page 70, Mr. Nathan Banks describes a new species of Brachynemurus under the name tuberculatus. The specimen used in drawing up the description was a female, and as I find a male of this species in the National Museum collection, a description of it is given here:

Brachynemurus tuberculatus, Banks.

Male.—Length, 21.5 mm.; expanse of wings, 33 mm.; greatest width of anterior wing, 3.6 mm.; length of antennae, 4 mm. Much smaller and more slender than the famale.
