The Caliente series is atypical in having the tegmina lanceolate 

 rather than truncate distad, these organs in the females being 

 distinctly more elongate. This is clearly a slight divergence 

 toward the condition of the typical race. 



Several specimens of nevadensis gilledei from Tintic, Utah, on 

 the other hand, show divergence toward the present race in 

 having the tegmina reduced, decidedly variable in the series, 

 proving that locality to be in the area of intergradation. 25 



Coloration. — A brilliant green and a yellowish brown phase of coloration are 

 found in nevadensis termius. In the most vividly green individuals the color 

 pattern shows its maximum intensification. The head has two postocular and 

 one subocular whitish line on each side, the more dorsal of the postocular bars 

 margining the eyes in the occipital region, which region also has a pale medio- 

 longitudinal suffusion. The pale medio-longitudinal band of the pronotum is 

 conspicuous, dark margined, and so continued to near the abdominal apex. 

 The pronotal lateral lobes have a pale band above and below the dark marking. 

 The tegmina are green, dark along the costal margin, with a weakly defined 

 pale line above this and another near the sutural margin. The caudal femora 

 have the pregenicular pink annulus decided, the dorsal surface pale and 

 (normally) with two slightly darker transverse bands weakly defined, 26 the 

 external face rather dark green with a narrow pale ventral border of the same 

 greenish yellow as the ventral surface. 



In the remaining specimens this type of coloration is found, but the markings 

 are variously less striking and blurred. Comparison with series of nevadensis 

 gillettei shows the coloration of that race to be very similar, specimens nearly 

 identical with each individual here examined being obtainable. In that race, 

 however, the large majority are of a rich brown color phase with color pattern 

 intensive, and nearly all have the dorsal marginal band of the lateral lobes of 

 the pronotum broader and extending over the lateral portions of the pronotal 

 disk. 



25 One specimen has fully caudate tegmina, a condition not shown in any 

 other example of the considerable series of nevadensis before us. 



26 In nevadensis nevadensis these bands are normally strongly defined, in 

 nevadensis gillettei they are normally obsolete.
