of the distal extremity of the caudal femora (when present) being 

 generally correlated with a similar infuscation of the dorsal face of 

 the caudal tibiae, the caudal femora, which are infuscate distad, 

 having the adjacent section of the distal half more or less inclined 

 toward tawny or yellow ochre. Pattern of caudal femora always 

 present. 



Female. Dorsal surface varying from being concolorous with 

 the lateral color through buffy citrine to russet, the intensive type 

 having the abdominal coloration largely produced by stipplings. 

 The segments of the abdomen in these contrasted specimens are 

 marked as in the male, but with decided blackish lateral patches 

 which extend more or less toward the median line proximad on each 

 segment. Color of the pale lines (when present) varying from 

 cream white to pale lumiere green and warm buff. Lateral color 

 varying from clay color (in this specimen pale chalcedony yellow on 

 head and pronotum) through course green to hellebore green, the 

 extreme recessive green condition being without distinct pale margins 

 to the lateral lobes and having the whole coloration uniform except 

 for a darkening of the distal margins of the ovipositor. Eyes and 

 antennae as in the male. Limbs varying as in the male, but in the 

 recessive green type uniform with the general coloration and with 

 the paginal pattern weak. Tegmina varying from a type nearly 

 uniform with the lateral color, to one with the costal and distal 

 margins of the color of the pale lines, humeral trunk claret brown 

 and remainder blackish brown with pale venation. Ovipositor 

 varying from uniform with mass color (recessive ^reen and brown 

 types) with margins edged distad with clove brown to blackish brown 

 to elm green washed dorsad with hazel and teeth blackish (extreme 

 intensive type) . 



Geographically considered, the coloration of the species shows 

 plasticity in some localities and constancy in others. The Arizona 

 and New Mexico individuals are all more or less recessive, the larg(> 

 Laguna del Gato series decidedly so, while the Marathon series is 

 about evenly divided (recessive, intermediate, and intensive). The 

 five Garden Springs adults are chiefly intensive, as are four of the 

 five Kent individuals. The Uvalde and Laredo specimens are 

 recessive, while the Beeville and Gregory representatives are average. 

 The Montelovcz and Jaral individuals are almost all intensivelj' 

 colored. 



From the basis of the Arizona, Marathon, Kent, Garden Springs, 

 and Laguna del Gato series it seems possible that direct and reflected
