green caiuhui, the pale lines weak; tegmina claret brown mesad,. 

 marginal field of the pale pattern; abdomen with weak narrow paired 

 pale lines, more or less distinctly edged dorsad by a line of claret 

 brown; ovipositor touchetl with pinkish proximad, the teeth black 

 tipped. Intensive females with the dorsal color covering most of the 

 occiput (not mesad), the cephalic and at least part of the caudal 

 section of the disk of the pronotum, in tone varying from claret 

 brown to mahogany red. The lateral color varies, in intensive 

 individuals (stuffed specimens) from olive green to ochraceous-tawny,. 

 passing into variscite green on the pleura and coxae of ochraceous- 

 tawny specimens, the lateral color covering the dorsum of the abdo- 

 men and limbs as well as the lateral and ventral aspects. Pale 

 pattern in intensive specimens broad, very broad on abdomen. Head 

 in intensive specimens with the vertical bars described in the male 

 rather weakly indicated, otherwise as in that sex. Pronotum with 

 the color of the caudal portion of the disk passing from the dorsal 

 color into that of the lateral regions, the pale bars outlined dorsad, 

 more or less distinctly with blackish; lateral lobes occasionally 

 washed with hoary white. Tegmina of intensive females with the 

 base color of the discoidal field blackish. Abdomen with the lateral 

 coloration more or less sprinkled with claret brown stipplings; 

 lateral pale bars more or less washed with flesh pink to rose pink, 

 sharply outlined dorsad on each segment by semi-lunate edgings of 

 black, which form continuous series conforming in arcuation to the 

 form of the abdomen; ovipositor in intensive specimens strongly 

 garnet brown to victoria lake on proximal two-thirds of dorsal 

 margin. All limbs wdth the genicular region more or less strongly 

 and sharply suffused with claret brown; all tarsi blackish. Caudal 

 limbs with the pattern as in intensive males, in one individual the 

 dorsal section of the proximal half of the femora is largely whitish. 



Both the type and allotype are intensive individuals. With a 

 single exception, all of the nymplis seen are in or approaching the 

 intensive condition, the exception being about midway between the 

 two extremes.. 



Distribution. — The present species has a very limited range, being, 

 found so far as known only at certain elevations in western Texas 

 and at an unlocated point in Coahuila, Mexico. Aside from Mara- 

 thon, Texas, the species is known only in that State from the Davis 

 and Chisos Mountains, the former range beginning about forty miles 

 northwest of Marathon, the latter lying seventy-five miles due south 

 from the same point. At Marathon (where it was very infrequent
