Color Notes. — General color ranging from light chalcedony 

 yellow to clear dull green-yellow (Ridgway), occasionally em- 

 browned by desiccation until it is nearly old gold, the greater 

 portion of the tegmina more brilliant, varying from light oriental 

 green to nearly dull citrine; dorsum of the head, pronotum and 

 stridulating field of the male tegmina washed with cinnamon-buff 

 to clay color. Occiput generallj^ with indications of a pair of 

 hessian brown lines diverging caudad; eyes ranging from rood's 

 brown to seal brown; antennae ochraceous-buff to ochraceous- 

 tawny, rather weakly annulate with darker. Pronotum with the 

 dorsum bearing abbreviate diverging lines similar to but less 

 frequently indicated than those on the occiput. Tegmina with 

 three spots of seal brown always indicated in the male sex, one 

 proximad, another at the apex of the arcuate portion of the anal 

 vein at its junction with the speculum and the third near the 

 other (toward the free margin) angle of the speculum. Limbs 

 quite greenish, rarely quite brownish (sudaii brown) on the caudal 

 tibiae, a blackish mark between the slits of the tympana of the 

 cephalic tibiae; all spines black, at least at the tips, on the caudal 

 tibiae largely brownish black. Apex of the abdomen more or less 

 yellow-ocher, the cerci ochraceous-orange to mars yellow. Ovi- 

 positor prout's brown. 



Distribution. — This species is found from the coastal prairie 

 region of Texas, south as far as the Brownsville region, north to 

 northern Texas (Wichita Falls and Dallas) . west as far as Co- 

 manche and Mission (Hidalgo County) in the same state, while 

 to the eastward the species ranges as far as eastern Louisiana 

 (Milneburg). It doubtless occurs in northeastern Mexico. 



Biological Notes. — This species was found fre(|uenting high 

 grasses along streams or in depressions (Rosenberg), in areas of
