Kinsey : Gall Wasp Genus Cynips 
357 
ogy. From Ames, Iowa; galls October 20, females October 29 (without 
year) ; Q. macrocarpa; C. P. Gillette collector. 
The present re-descriptions are based on all of this type material 
compared with my Indiana, Minnesota, and Kansas material. 
INQUILINE . — Synergus villosus Gillette (acc. Gillette 1890). 
This is the most eastern representative and the first-known 
variety of the species. It is usually not a common insect and 
it is not well represented in our collections. Superficially the 
gall appears as a tangled mass of coarse hairs, but the slender 
tips break off on handling and expose the broader bases of the 
spines, leaving the gall more like the agamic Cynips gemmula 
in appearance. The gall of villosa is hardly distinguishable 
from the galls of consocians and of alaria , from southern 
Kansas and the southern Rockies, respectively. Villosa in- 
sects are more rufous, with shorter wings than alaria and with 
a more slender thorax than consocians. 
Gillette recorded these galls as appearing in the mid-summer. 
Weld found pupae (in galls from Medina, N. Y.) on August 24 
and September 4, and cut active adults out of galls early in 
October and (from northern Illinois material) on November 1. 
On October 23 (1926) the insect had already emerged from a 
gall I collected in southern Indiana. Gillette’s galls collected 
on October 20 gave adults on October 29. My material from 
Minneapolis emerged on November 10, from central Indiana 
on November 20, and from central Illinois on December 8. 
The Marlatt material from Riley County, Kansas, emerged in 
January (one specimen is labelled September!).

FEMALE. — Very close to variety villosa from which consocians is 
distinguished by being more robust and darker. Head and thorax dark 
rufous with some black, the abdomen bright to dark rufous with much 
piceous or black on the posterior half; head distinctly wider than the 
thorax, very finely, irregularly rugose; the thorax much reduced in 
size but relatively robust, half again as long as wide; the parapsidal 
grooves nearly obliterated; scutellum rather smooth with a not heavy 
punctation, anteriorly depressed to form the undivided, poorly defined 
foveal groove; the ridge between the scutellum and the rest of the 
mesonotum only very poorly indicated; mesopleuron punctate and very 
hairy; abdomen enlarged, rather elongate, entirely hairy on the sides
