194 NORTH AMERICAN OEDIPODINAE (oRTHOPTERA; ACRIDIDAE) 
^\ iiigs with disk chalcedony yellow to amber yellow (in vast majority), 
rarely na])les yellow; bar similar to that of C. coconino in form and extent, 
bnt more uniform in intensity, more solid and generally more sharply defined, 
in color mummy brown; distal p(jrtion of wings ranging from clear hyaline 
to very faintly infumate. Ventral surface ranging from isabella color and 
light brownish olive to fuscous-black witli a wash of dusky dull bluish green; 
pale areas described on sternum of C. coconino indicated, but not invariably, 
in this sj)ecies. C'audal femora with color as described for coconino, caudal 
tibiae deep orient blue to dark tyrian blue, otherwise as in (\ coconino, cau- 
dal tarsi pinkish buff, lined dorsad with bluish. 
coiisidor as pai-atypes the entire series before us (other 
than tyiie and allotype)— forty-two males and fifty-four females, 
taken in Lee Oanyon, Sitring Mountains, Nevada, August 18 to 
20, 1919, at elevations of from 7000 to 8500 feet, and one male 
tuid two females taken at 10,200 feet on Oharleston Peak, Spring 
Mountains, Nevada, on August 19, 1919, all secured by Kehn 
and Ilebai’d. This series shows, as is demonstrated in the above 
table, that the sjtecies varies individually very greatly in size, 
(‘ven at the same elevation in Lee C'anyon; also that the form of 
the fastigium varies considerably in shape and in the relative' 
liroportions of the same, although this ai'ea is, when the sei'ies is 
considere'd as a whole, of a distinctly narrower type than in cu- 
coniiio. ddu' basic coloration is variable, as the color descri))- 
tion shows, but tlu're' appears to be some environmental corre*- 
lation h(‘r('. The mate'rial taken fi'om seven thousand to seven 
thousand, two hundre'd fee't is pak'r, more grayish in general 
tom*; that from eight thousand to eight thousand, five hundre'd 
fe(‘t is moi'(' blackish,-' as is also that from Charleston Peak. 
4'his is probably du(' to responses to some ('nvironnu'ntal in- 
fluences at th(' two localitii's. At seven thousand, two hundred 
feet w(' hav(‘ a i)ark-lik(‘ region, of juniper and jiinyon with sage 
bi'ush, and oja'ii aia'as showing some bare gray limestone, much 
sunlight and strong ri'tli'ction; at ('ight thousand to ('ight thou- 
sand, five hundj'cd fei't wv have a la'gion of yellow ])in(' foia'st 
willi small glad(‘s and sonu* cut-over arc'as, but as a whoh' om' 
of shadows and r(‘duced light, with tin* linu'stone of tlu' 
mountains largely manih'd with lu'C'dh's and dry soil. 
-'Several individuals from Hus elevation are as pale and as grayish as 
those trom seven thou.sand, two hundred bad. In oih' casc'this is clearly due 
to the- specimen being tencial, and a sindlai' caus(> may i)e I'csponsibU' for tlu' 
otlau’s, although from our knowledge of the inunediati' locality restriided 
sei'tions a[)pi'o\iniate the conditions found at seven thousand, twohundi'ed 
bat.
