OAK GALL-FLIES. 115 
Cynips suttonii Bass. 
Received September 25, 1882, from William Sutton, San Francisco, three very large 
galls belonging to above species, found on twigs of Q. lobata. Several of the gall- 
flies issued November 8, 1882, and another one January 2, 1883. Chalcidians issued 
from January 2 to 13, 1883. 
Cynips q.-floccicola Riley. 
Producing a fuzzy gall on underside of leaves of swamp oak. 
C. q.-decidna Bass. 
Received November 10, 1873, from G. W. Lettermann, Allenton, Mo., apparently 
the same or a very similar gall to C. q.flocci, on twig of white oak. The insects were, 
however, in the larva state July 8, 1874. Nothing was bred. 
A lot of galls, which also resemble those of flocci, were received February 14, 1879, 
from E. A. Schwarz, Jackson, Miss., but a fly which had issued on the way appears 
to be identical with C. q. decidua. Some of the galls contained Chalcidian larvae. 
C. q.-flocci W. 
Found galls on white oak September 27, 1870, at St. Louis, Mo. Found apparently 
the same galls also on black oak, burr oak and red oak. 
C. lance Fitch is perhaps synonymous. 
Bassett has another gall with totally different kernel. 
I have insects and the gall of his flocci. 
Flies from galls on post oak issued January 20, 1^72. 
Cynips q.-prunus Walsh. 
One gall of the above species was received June 11, 1882, from D. S. Sheldon, 
Griswold College, Davenport, Iowa, and some dry galls from J. G. Barlow, Cadet, 
Mo., March 18, 1883. 
Cynips q.-tubicola O. S. 
Galls of this insect were received December 31, 1878, from W. B. Flippier, of Tell- 
ville, Ark. They were found on the leaves of post oak. Others galls were also 
received from Dr. J. W. Sparkman, Plantersville, S. C. The flies issued during the 
mouths of January and February, 1879. There also issued quite a number of a 
greenish-black chalcid fly. Prof. W. S. Barnard also collected the gall at Atlanta, 
Ga., in November, 1880, from which the cynipids and a chalcid which is very likely 
identical with those referred to above, issued during January and February, 1881. 
Cynips cadncus W. (?) 
Round galls in clusters on the midrib on underside of leaf of Quercus undulafa, of 
the size of a very small pea. Collected October 10, 1874, and examined December 16, 
1876, when one cynipid was found. This gall looks much like 159*. October 1, 1880, 
received the same gall from J. Schenck, of Mt. Carmel, Ills., found on Q. muhlembergii. 
The larvte were only just hatching; gall tasteless, a pale circle around the larva. 
It is evidently caducus W. 
Cynips q.-spongifica O. S. 
May 19, 1870. Galls are found to contain pupae at this date. Flies issued May 31.
