modesta to be quite distinct, as indicated sufficiently in the key. 
To my original description may be added that Sc ends about 
opposite or slightly beyond, or at most but slightly proximad of 
the base of the radial sector (fig. 5) ; the petiole of R2 +3 (measur- 
ed in a straight line) is about .55 as long as R3; the petiole of 
the media, measured from the crossvein, about equal to Ml +2; 
the distance between crossveins along the media less than 1/2 as 
long as the m-cu crossvein. In the western specimen there is a 
very faint suggestion of a cloud on the r-m crossvein. The fore 
basitarsus is about 3/ 4 as long as the tibia. The basal clasper 
segment is somewhat enlarged, mesal process short with some 
stout apical setae; apical segment broadest beyond the middle 
when viewed from the side, thence tapering to the tip; viewed 
more ventrally the sides are more or less parallel (fig. 3) . 
Specimens from Ithaca N. Y., April, May; Black Mts., 
N. C. May; and S. Jacinto Pk., Cal., August. Type in my col- 
lection. 
Dixa similis sp. nov. 
Closely resembling D. modesta, differing chiefly in the 
characters given in the key. 
Male. Head including proboscis, palpi, and antennae, 
brown; front shining. Thorax including scutellum, yellow, with 
three dull dark brown stripes, the middle one divided by a hair 
line, the laterals abbreviated anteriorly; metanotum and lower 
part of the pleura brown. Abdomen brown, including the glo- 
bose basal segment of the clasper whose mesal process is simple 
and provided with a few stout apical setae (fig. 7); terminal 
segment rather tapering when viewed more or less from the side. 
Legs yellow, tarsi and tips of hind tibiae a little darker; fore 
basitarsus about 3/ 4 as long as the corresponding tibia. Wings 
hyaline, very faintly cinereous, veins yellowish, crossvein not 
clouded; Sc ends in the costa at least the length of the r-m cross- 
vein proximad of the base of the radial sector, the distance be- 
tween the crossveins measured along the media about equal to 
the length of the m-cu cross vein; petiole of R2-f3 (measured in
