A NEW SPECIES OF THE GENUS MYMAR FROM THE 
WOODS OF MARYLAND WITH AN IMPORTANT 
DESCRIPTIVE NOTE. 
By A. A. Grravu_tt, 
Bureau of Entomology, Washington, D. C. 
Mymar cincinnati sp. nov. 
Male: Similar to venustum (female type) but the antennz 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 cephalad 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.

Mymar venustum has the caudal wing shaped like a long thick 
bristle with the hooklets 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 hooklets) is much longer than in the other genera. This 
blade part of the wing must break off easily and this accounts for
