the northern specimens do thus average differently in respect 
to color. Vorisi is very close to gig as, but has less bright 
rufous on its face and mesonotum. From major , vorisi differs 
in being a larger and much more robust insect. Altho vorisi, 
gig as, and major occur in much the same territory, they are 
on distinct oaks {gig as on Q. lyrata and the chestnut oaks, 
major on Q. alba), but the host isolation appears to break 
down in some cases, for perhaps ten per cent of our material 
of these insects is distinctly intermediate between the several 
varieties. 
Very young galls of vorisi were found in southeastern 
Kansas as early as June 8 (1927). Full-sized galls were 
obtained by June 15, and galls large enough to breed were 
found on July 4. This represents earlier development than we 
know for the northeastern varieties of the species. Most of 
the adult insects emerge during the first winter, but about ten 
per cent of our material has emerged in the second winter 
after collecting. The emergence during the first winter is 
practically continuous from early December to the end of 
February, the bulk of it occurring well before the end of 
December; the emergence in the second winter was confined 
to December. The recorded emergence dates are December 2, 
8, 9, 10, 12, 15, 17, 18, 19, 20, 22, 23, 26, and 28; January 2, 
4, 5, 10, and 25; and February 2, 6, and 20. 
Almost all of our Kansas material of this insect was 
collected by Dr. Ralph Voris, of the Southwestern Missouri 
State Teachers College. For several years Dr. Voris has been 
a companion in my field work, and many thousands of speci- 
mens of Cynipidae and many hours of help on field routine 
are to be credited, to him. He has an appreciation of the 
importance of individual variation, and to this fact we are 
indebted for the unusually large series which we have of 
several of the Cynipidae from Kansas and western Missouri.
