Queensland colonies Al; A2; A6; and A7 showed entire compati¬ 
bility. They were designated as Group 1. 
Queensland colonies A3; A4; and A5 showed entire compatibility. 
They were designated as Group II. 
Members of Group I and Group II were consistently incompati¬ 
ble inter se. 
Members of both Group I and Group II were consistently incom¬ 
patible with Bl, the Sutherland population. 
When the specific locality label for each colony was uncovered, it 
was found that the members of Group I (Al; A2; A6; A7) had been 
closely associated geographically when collected nine years before: 
Al and A2 had originally been taken a few feet apart at Para¬ 
mount Point. 
A6 had been taken a few feet from A1-A2 at Paramount Point. 
A7 had been taken at Montville, a short distance away. Thus all 
of these had originally been parts of a closely circumscribed 
population. 
The members of Group II (A3; A4; A5) had likewise been col¬ 
lected in close proximity, near the town of Nambour, approxi¬ 
mately 7 miles from the first group. 
These tests were repeated with the same colonies on March 20, 
1977, when the Queensland colonies had been maintained in the 
artificial nest for more than thirteen years and that from Sutherland 
for more than nine years, and one of the Ashton colonies, collected 
January 4, 1973, was added. Colonies were renumbered as follows: 
#1— Montville, Queensland (A7 in the October 23, 1972 tests 
recorded above.—Group I). 
#2— Nambour (Group II in 10/23/72 tests above). 
#3— Colony Al in the 10/23/72 tests above (Group I). 
#4— “X” in the Ashton-Ashton tests described above. Ashton, Jan¬ 
uary 4, 1973. 
#5— Sutherland, January 12, 1968 (Bl in the 10/23/72 test above). 
#1 X #2 (Old Group I X Group II)—Violent attack (A) 
#1 X #3 (Old Group I X Group I)—Complete compatibility (D) 
#1 X #4 (Old Group I X Ashton) 
Test #1—Violent attack (A) 
Test #2—Extreme avoidance (A/B) 
#1 X #5 (Old Group I X Sutherland)—Extreme “startle” reaction 
and avoidance (B)
