The length by the greatest breadth of the ovipositor in females from 

 a number of localities is as follows. Atypical /. furcifera. Lost Mine 

 Peak, Texas, 7.7 by 2.6; Sycamore Canyon, Arizona, 7.3 by 2.4 mm.; Hot 

 Springs, New Mexico, 7 by 2.4; Jemez Hot Springs, New Mexico, 6.7 by 2.3;

 Mexico of the atypical form found in the southwestern United
