on the head, continued over the lateral lobes and pleura, suffusing 

 the base of the costal field of the tegmina and coloring the proximal half 

 of the discoidal and humeral veins of the same and the dorsal half of 

 the proximal abdominal segments. Wliite lateral bars as in P. acris, 

 but not present on the caudal femora. Eyes clay color marbled with 

 bistre; face and mouth parts sprinkled with small spots of brown; 

 antennae tawny, darker proximad. Caudal femora of the general 

 color with the dorsal half of the lateral face pale vinaceous bordered 

 ventrad by a line of dots of brownish.

The type specimen is the only one examined by the authors. It 

 was taken on the extreme edge of the canyon plateau and was found 

 clinging to a wisp of dry grass, the only vegetation along the extreme 

 edge of the plateau above the trail. 



SYRBULA st&i. 

 Syrbula fuscovittata Thomas. 



At Tucson on July 26 two males and three females of this species 

 were taken from high weeds growing in damp soil surrounding a pool. 

 An immature female was also taken in Sonora Road Canyon, Tucson 

 Mountains, July 25. 



One of the males is in a condition similar to that of the specimen of 

 the same sex recorded by Rehn.^ Two of the females are in the green 

 phase and the other in the brown phase, with, however, much very 

 pale green on the face and sides of the head, lateral lobes of the pro- 

 notum, tegmina and caudal femora. The males are smaller than the 

 average of a series of eight from the Huachuca Mountains. 



Syrbula modesta Bruner. 



This rather diminutive species was taken at elevations ranging from 

 4,900 to 5,800 feet in the Grand Canyon, three males and two females 

 being included in the series. Apparently this species has two color 

 phases, as all the specimens seen are in a brown phase of coloration, 

 while Bruner's original description shows that his specimens had green 

 or greenish the predominating color.
