114 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
•ma]] kernel, usually of an oval form and 08 of an inch long; this kernel perfectly 
free and containing the larva. Color of outer gall pale-green, with usually a pale 
rosy check, and having pale yellowish blotches. Color of inner gall fulvous. The 
galls had completed their growth, though the leaves had not been out more than a 
week. Flavor subacid. Flies issued during middle of May. 
Cynipr(Xeuroteru8) rileyii Bassett. 
Received April 25, 1880, from John A. Warder, North Bend, Ohio, some twigs of 
Querent castanea thickly covered with the galls of this insect. Others were received 
March 5, 1883, from J. G. Barlow, Cadet, Mo. Cynipids issue during April and early 
May. They are preyed upon by a species of Chalcid. 
C. q. -sculp ta Bass. 
A translucent gall on Q. imbricarid. This is Bassett's C. q. 8culpta, which hi 
from Q. rubra. The fly has cloudy wings and is probably nubilipennis Harr. Harris 
probably described the gall, but not correctly. 
Cynips q.-cornigera O. S. 
Found on Q. t'm&rican'a, St. Louis, Mo. Galls of the same species were also obtained 
at Kidgewood, N. J., on Q. palustris, and the Hies were issuing for two weeks after 
September 8, 1871. They are the true sexes and were very active. 
Cynips q.pedunculata. 
Received May 22, 1883, from J. G Barlow, Cadet, Mo., one of these galls, found 
growing on the margin of Q. obtusiloba. Several were also found May 23 at Wash- 
ington, D. C, on leaves of Q. prinos ; a large number of them were, however, de- 
stroyed by birds which had eaten them, leaving only the petiole. 
The flies were issuing from May 26 to June f>. Some were confined to some leaves 
and twigs on the same oak, covered with gauze, but no galls were formed. 
On the 6th of May, 1884, the galls were found to be already fully formed. 
C. q.-vcntrico8a Bass. ? 
In May, 1870, it was observed that a week before the 8th of that month there was 
no trace yet of any galls, while on the 8th they were almost fully grown. Large 
clusters of these galls up to fourteen and more aggregate around a twig, each ftp- 
pressed to one another and terminating in a prominent nipple. Color, green with a 
roseate tint and thickly covered with bluish-white hairy pubescence. Inside dense 
and spongy, becoming harder towards the cell. Flavor pleasantly subacid or rather 
insipid. Larval cell at base close to twig. Larva quite small at this date. 
By July 31 a very different growth has formed around the twigs of the same trees, 
caused by several spherical growths around the axis, which, as they enlarge, become 
closely coutlueut. 
Their outside is green aud roughened with a number of fulvous blotches, very 
much like the green bark. Flesh tough, yellowish, insipid and leathery, becoming 
whiter and more leathery towards the twig. It does not look like a fungus, and yet 
has no trace of insects, though in the more woody center there are pellucid spots 
which would indicate it to be a gall. 
Similar galls were found by Mr. Bassett in October, 1871, on red oak and on Q. ilici- 
folia. 
It was found also on Q. imbricaria. May 20, 1873. at St. Louis. Mo. 
Some old galls which were opened contained the dead gall-flies and three different 
parasites.
