MORGAN HEBARD 145 



Coloration. — Males. General coloration rather light brown, with a broad 

 postocular band of dark brown on each side extending to the principal sulcus 

 (or in other series to the caudal margin) of the pronotum, this often margined 

 dorsad by a narrow band, which is paler than the general coloration. Abdo- 

 men with proximal dorsal segments maculate laterad with dark brown to 

 varying degrees. Caudal femora very light brown, heavily twice banded with 

 blackish brown and with genicular areas often as dark. Caudal tibiae pink. 



Five males have the paler portions showing a greenish tinge, this most con- 

 spicuous on the limbs; in three of these the paler portions are pale yellowish- 

 green. 



The females are usually paler, the general brown coloration more reddish. 

 In all, the postocular band is subobsolete and in only the two or three darkest 

 examples are the dark abdominal markings present. The two dark bands of 

 the caudal femora are distinct, but as pronounced as in the male sex in but 

 four specimens. The caudal tibiae are similar to those of the males, though in 

 the paler examples the pink is more dilute. 



Specimens Examined: 65; 32 males, 16 females, 9 immature males and 8 

 immature females. 



Texas: Kerrville, Mission, Laguna del Gato, Uvalde, Del Rio, Sanderson, 

 Marathon, Kent, Neville Spring in Brewster County, Canon behind Pulliam 

 Bluff in Chisos Mountains and Quitman Mountains. 



The adults, with one exception, were taken from August 5 to 

 September 13, 1912 by Rehn and Hebard. 



One male from Mission and a series of nine males and ten 

 females from Laguna del Gato, bearing the same data as the type, 

 may be considered paratypes. 



The type series was found occasional on small rounded hills 

 covered with loose gravel and bearing scattered bunches of low 

 bushy plants, in company with a slightly less abundant species 

 of Rhabdotettix. The Melanopli were generally distributed 

 through the clumps of plants, the present species found more 

 numerous in a low green rhamnaceous shrub (probably Condalia 

 obovata), in which Dichopetala castanea Rehn and Hebard was 

 locally abundant. The species was found to be everywhere 

 thamnophilous, and was taken up to an elevation of 5000 feet in 

 the Quitman Mountains of extreme western Texas. It was twice 

 found on a sensitive-leaved acacia, Acacia berlandieri, and twice 

 singly on sotol, Dasylirion species.
