of segments 2 to 5, not at all produced dorsally, the second segment 
covering a half to two-thirds of the whole abdomen; the wings much 
reduced but relatively broad, 0.30 of the body in length, reaching at 
most one-quarter of the way along the second abdominal segment, only 
the subcosta and basalis defined; length 2.7 to 4.3 mm., averaging about 
3.8 mm. Figures 367, 410. 
GALL. — Mature gall straw-yellow, staining browner in color; up 
to 13.0 mm. in diameter, the spines up to 2.0 mm. in length, rather 
flexuous, slender; the whole gall appearing as a dense mass of coarse 
and tangled hairs; on the leaves of Quercus macrocarpa. 
RANGE. — Kansas : Winfield (types, R. Voris in Kinsey coll.) . 
Either an Ozark variety extending westward to eastern Kansas, or 
a Texas variety extending northward to southern Kansas; the material 
insufficient to allow more precise prediction. Figure 59. 
TYPES. — 117 females and many galls. Holotype and paratype 
females and galls in the Kinsey collection. Paratype females and galls 
in the U.S. National Museum, the American, Field, Stanford, and Cali- 
fornia Academy Museums, and the Museum of Comparative Zoology. 
Labelled Winfield, Kansas; galls September 7, 1927; insects November 
20 and December 5 and 17, 1927 ; Q. macrocarpa; R. Voris collector. 
This is either the Ozark or the eastern Texas variety of the 
species. In addition to the type series from southeastern Kan- 
sas, I have some material without data other than the record 
that I collected it in 1919-20. It was therefore probably col- 
lected in the southern United States not further north than 
northern Texas or southern Mississippi. This suggests that 
consocians is an eastern Texas variety finding its northern 
limit in Kansas. The galls are identical with variety villosa, 
and the insects of consocians are very close to villosa and 
alaria. These three varieties would hardly be distinguished 
except for their distinct ranges and the fact that among these 
sub-apterous Cynipidae the simplification of structure has pro- 
ceeded so far that one may use only a part of the characters 
available among long-winged insects. The type series of con- 
socians is a fine collection large enough to insure constancy in 
the few characters on which the variety is established. 
Galls from the type locality were full-sized and contained 
very small larvae early in August (1927). By early Septem- 
ber the larvae had grown enough to be suitable for collection 
for breeding. Adults emerged from these galls on November 
20 and December 5 and 17 (1927).
