2. The color of the aiiteniiac is somewhat more brownish. 3. The face 
is aciculated all over its surface, without any smooth spot in the mid¬ 
dle. 4. The scutullum is drawn out into a point, almost subconical. 
5. The wings have no areolet (two specimens have an irregularly formed 
areolet on the left wing only) • this cell, however, cannot even be con¬ 
sidered as a true areolet, as, instead of being formed by a bifurcation 
of the second transverse vein, it occupies the lower corner of the radial 
area. 6. The brown cloud near the tip of the subcostal vein is larger 
and more distinct; this portion of that vein is very stout, dark brown, 
and is distinctly attenuated before reaching the margin, whereas in 
D. nelmlosus it has the appearance of touching the margin, and is 
paler brown and less distinctly attenuated. 7. The pale brown clouds, 
in the form of streaks, towards the tip of the wing, which exist in D. 
nebulosus^ are wanting here. 
One % and eight 9 specimens. The % is easily distinguished by 
the third antennal joint, excised below. The coloring of this species, 
like that of the preceding, is frequently more or less brownish or red¬ 
dish, especially on the face, the collare and the humeri, according to 
the maturity of the specimens. 
Cynips-galls on the Kose. 
I. The Galls. 
I am acquainted with eight cynipideous galls on the diiferent kinds 
of roses of this country. My account of them is, perhaps, not so com¬ 
plete as I would desire it, as most of these galls have not been observed 
by myself, but were communicated to me by others. 
1. An agglomeration'of hard celh round a branch^ the whole covered 
with long and dense greenish filaments and forming a moss-like mass 
of an inch and a half or more in diameter. This, or a similar gall 
(see Reaumur, vol. Ill, Tab. 47) is well known in Europe under the 
name of the bedeguar^ (from the Hebrew bedeguach.^ said to mean rose- 
apple')^ and was formerly used medicinally. I cannot discover any 
difference between the gall-fly obtained in this country and some Euro¬ 
pean specimens of R. rosae^ communicated to me by Mr. Rheinhardt. 
One specimen of the gall from New York, was communicated to me by 
Mr. Grlover; another, with numerous female Rhodites reared from it, 
by Mr. Norton. Mossy galls of simillar appearance, but much smaller.
