19171 Girault-New Species of the Genus Mymar 99 the spiracle is oval and a short distance off the cephalic margin. The same otherwise. Mandibles 4-dentate. Described from one female on a tag in the U. S. National Museum from Franconia, N. H.
Type: Catalogue No. 20427, U. S. National Museum, the female on a tag, a caudal leg and the head on a slide. A NEW SPECIES OF THE GENUS MYMAR FROM THE WOODS OF MARYLAND WITH AN IMPORTANT
DESCRIPTIVE NOTE.

Mymar cincinnati sp. nov.
Male: Similar to venustum (female type) but the antennae are entirely black, the base of the blade of the fore wing is rather broadly infuscated, there are on the fore wing 43 primary marginal cilia (instead of 34), the midlongitudinal line of discal cilia runs from apex nearly to the base of the blade (instead of into the costal margin, farther from base); and most of the discal cilia of the fore wing are caudad of the midlongitudinal line instead of cephal?d as in the other species.
Scape long, curved; flagellar joints elongate, subequal, 2 eight times (or more) longer than wide. One male captured by sweeping grass in an open wooded bog, Glenndale, Md., August.
Type: Catalogue No. 20468, U. S, National Museum, the speci- men on a slide.
Mymar venustum has the caudal wing shaped like a long thick bristle with the booklets at its apex. In the above new species it is similar but prolonged beyond the hooklets in the form of a hair as long as the part from base to the hooklets and after that length widening into a very linear blade of more than half the length of the hairlike pedicel and which bears a few long marginal cilia caudad. In Mymar, then, the hind wing has a short, very linear blade on a long pedicel while the petiole of the wing (from base to booklets) is much longer than in the other genera. This blade part of the wing must break off easily and this accounts for
