they touch the humeri: the intermediate gi’ooves generally appear as smooth 
lines, unless viewed obliquely; scutellum rugose on the sides, more smooth in 
the middle, but, in general, not so rough in appearance as in most other species : 
abdomen ( % ) black, ( 9 ) I’ed, fringed with pale yellowish hairs on the hind borders 
of the segments; tip of the point on the underside of the 9 abdomen brown: 
basis of % femora brownish; wings hyaline, 9 somewhat tinged with brown 
and with a more or less distinct cloud on the radial area and its surroundings; 
in both sexes, the second tranverse vein has no projection within the radial 
area and is arcuate ; the areolet is of a moderate size, larger in 9- 
Two % and 16 9 specimens reared by me in Washington, from the 
galls. These have been described above (No. 6). 
The fringe of pale yellow hairs on the border of the % abdominal 
segments seems to be peculiar to this species, as it is quite distinct in 
all my specimens, whereas I do not notice it in the numerous speci¬ 
mens of other species, communicated to me by Mr. Norton. 
R. veriia resembles in coloring R. hicolor and R. ignota; but the 
latter is easily distinguished by.the peculiar coloring of its wings; R. 
hicolor by its less pubescent, more roughly sculptured, and therefore 
more opaque thorax and scutellum, the structure of its second trans¬ 
verse vein, etc. 
Rhodites hicolor Harris. 
% 0.15 long, black ; feet red, coxse black. 
9 0.15—0.16 long, abdomen red ; feet and coxae, except at the base, red. 
This species is so much like the preceding, in both sexes, that it will be 
sufficient, for its recognition, to notice the differences. 
Thorax less pubescent, somewhat more roughly sculptured and therefore 
more opaque; parapsidal furrows somewhat deeper; the intermediate furrows 
appear as distinct ridges when view'ed obliquely; scutellum, likewise, more 
deeply rugose; the smooth, glossy spots existing on the pleurae of some other 
species are hardly apparent here, these spots being sculptured more or less like 
the remainder of the pleurae; the brownish cloud on the radial area of the 9 
is more intense ; the % wing is also somewhat clouded along the stout veins 
and has two indistinct clouds in the apical area; the second transverse vein 
has a light projection about its middle, in the radial area (in some specimens 
this projection is very small); the veins forming the anterior angle of the 
areolet. as well as the portion of the cubital vein, preceding the areolet, in this 
species are thin, often subobsolete ; said portion of the cubital vein being often 
merely indicated by a brownish streak (without vein); there is a short, pale 
hrovjn line, as if a stump of a vein, close by the posterior angle of the areolet, (that 
-is the angle, which is nearer the tip of the wing), on its out and underside. 
This last mark^ trifling as its seems to be, exists in precisely the same degree 
of distinctness, in the nine specimens which I have before me.
