Rather larger than Nebraska, Colorado, Utah and New Mexico- 

 individuals, but otherwise inseparable. The male has the base color 

 greenish, the female reddish ash. 



Mermiria texana Bruner. 



Carr Canyon, Huachuca Mountains, August, 1905 (Skinner), 3 9 . 



These specimens are quite typical of this richly colored species which 

 has previously been recorded from Fort Grant, Arizona. 



SYEBULA Stai. 

 Syrbula admirabilis (Uhler). 



San Bernardino Ranch. 3,750 feet, August (F. H. Snow), 1 d", 1 9 . 



The female specimen has the pronotum slenderer than is the case in 

 seventeen female specimens from east of the Rocky Mountains. It 

 is possible that the specimens from Arizona represent Stal's S. leucocerca, 

 which is clearly either admirabilis or a closely allied form, but this 

 matter involves the examination of Stal's type. 



Syrbala fuscovittata Thomas. 



Carr Canyon, Huachuca Mountains, August, 1905 (Skinner), 10 c^, 

 10 9 , 1 immature individual. September and October, 1905 (Bieder- 

 man), 5 d", 1 ?. Huachuca Mountains, July 13 (Schaeffer), 1 d". 

 Palmerlee, August (Schaeffer), 1 $ . Douglas, August (F. H. Snow), 1 d" , 

 1 9 . San Bernardino Ranch, 3,750 feet, August (F. H. Snow), 1 9 . 



This very interesting series shows that both sexes exhibit consider- 

 able color variation, in the male being chiefly due to either the greenish 

 or grayish tone of the lighter areas, the general clove brown or blackish 

 color remaining much the same, while in the female variation is due to 

 the presence of two phases with different base colors. The greenish 

 phase has light green by far the predominating color, while the brown 

 phase ranges from warm browns to a decided umber, the dorsum of the 

 tegmina being ashy gray in several individuals. One female specimen 

 has the tegmina and limbs colored as in the green phase, while the 

 pronotum and head show practically no greenish, being nearly as in the 

 brown phase. The single male labelled Huachuca Mountains is ex- 

 tremely interesting as it appears to represent the freshly emerged 

 condition, as the date (July) would also testify. This specimen is 

 somewhat shrivelled, as would be expected in the drying of soft chitin,, 

 and in color is quite striking, the insect being generally pea green, the 

 dorsum of the pronotum buff, the eyes and distal portion of the anten- 

 na walnut brown the tegmina whitish hyaline and the wings distinctly 

 infuscate.
