Abstract

This paper discusses only species occurring in America north of Mexico and no table to separate the males has been included since Prof. T. D. A. Cockerell published a table for this sex in the Canadian Entomologist for June, 1912, pp. 167-170. The key to the females includes all the species for the region under consideration in which the female sex has been described. In the table here presented the characters used for separating rufitarsis Sm. from comstockii Cress. and lucrosa Cress. from moesta Cress. are the characters used by Prof. Cockerell in a table to separate the types of the Cressonian species and some non-Cressonian species which he consulted in the collection in Philadelphia. The illustrations were made with a camera lucida, attached to a Zeiss binocular microscope.
