reared by him from the gall (see above, No. 6). The male is conside¬ 
rably larger than that of R. verna. 
Rhodites ignota n. sp. 
0.12—0.13 long, black; feet red; coxse and base of femora black. 
9 0.14 long, abdomen red; feet, including coxse, red. 
Head and antennse black, mandibles brownish red, thorax black, densely 
rugose, opaque; parapsidal furrows not very distinct, intermediate ones like¬ 
wise; the latter, in some specimens, have the appearance of small ridges ; no 
distinct, smooth, shining spots on the pleurse, especially in the 9; wings: se¬ 
cond transverse vein angularly bent, with a projection in the middle, inside of 
the radial area; (in some specimens, especially the %, this projection is quite 
large, like the stump of a vein); radial area shorter than in the other species, 
the radial vein being slightly arched; the margin of the wing within this area 
is thickened, so as to appear like a vein, closing the area; a brown spot between 
the areolet and the anterior margin; another one at the tip of the radial vein, 
near the margin; (in the these spots have often very little extent, appearing 
only like brownish margins along the veins); the space of the radial area be¬ 
tween these spots is hyaline; the tinge of the 9 wing is somewhat yellowish, 
whereas that of the % is more hyaline. 
The thorax of this species is proportionally smaller than the thorax 
of R. verna or hicolor^ and hence the body has a more slender appear¬ 
ance. 
Four % and two 9 specimens were in Mr. Norton’s collection, with 
labels indicating that they had been obtained from a “ smooth rose 
gall”. Is it the gall described above under No. 5 ? This seems doubt¬ 
ful, as two other males, apparently of the same species, were reared 
from quite a dilferent gall, described under No. 7. 
ERRATA. 
Some corrections in my paper have become necessary in consequence of my 
having made a change in the latter part of my manuscript, and having forgot¬ 
ten to introduce a corresponding alteration in the preceding text. These cor¬ 
rections refer all to page 35 and are as follows:— 
Line 1 and 2 from the top. Instead of Another Horth American species par¬ 
asitical in the gall of R. radicum, read: My Aulax pirata, parasitical on rose- 
galls, is, etc. 
Line 16 and 16. For Aulax semipicea Harris is obtained, read: Cynips semi- 
picea Harris is probably an Aulax, obtained etc. 
Line 17. Strike out the word was. 
Line 23. For three read two. 
Line 24. For A. infuscatus read A. pirata. 
Line 2 from the bottom, for A. semipicea read A. pirata. 
On page 39, line 8 from the bottom, after the word antennse, add: Length,. 
0.08; 9 about 0.1.
