strongly quadrate, superiorly with fourteen spines, inferiorly with twenty-six. 

 Supra-anal plate hroad, apex hroadly rounded, shallowly sulcata. Cerci with the 

 tips sharply bent inward. Subgenital plate bicarinate, centrally tumid, style 

 sheath extended. 



General color approacliing gallstone yellow (Ridgway's Nomenclature of 

 Colors), completely sprinkled with blotches and dots of dark maroon-purple, these 

 being grouped into an irregular stripe on the ulnar vein, and forming rings en- 

 circling scattered spots of yellowish w^hite on the tegmina, the margin of the 

 lateral lobes of the pronotum being corded with the same. The femora are 

 darker than the general tint, the spines black; the tibiae are decidedly blackish,

The specimen on which this species is based differs rather de- 

 cidedly from both of the previously known species — olivaceo viridis 

 and tarasca. It departs from olivaceo-viridis in the non-sulcate an- 

 terior tibiae and the different shaped tegmina. From tarasca it 

 differs iu the broadly rotundate lower margin of the lateral lobes 

 of the pronotum, the non-sulcate anterior tibiae and the rather con- 

 cave disk of the pronotum. Specimens of tarasca have been re- 

 corded from the same locality (^Biol. Cent. Amer., Orth., p. 366). 

 This species is dedicated to my friend, Mr. A. N. Caudell of Wash- 

 ington, D. C, a student of the Orthoptera. 



Size medium. Head with occiput punctate, the punctures resolving into lines 

 diverging from the centre; vertex narrowly sulcata, contingent witli the front; 

 antennae moderately long, almost reaching the tip of the hind femora; eyes glo- 

 bose, half as deep as the infra-ocular genae. Pronotum with the disk rather 

 concave, the anterior margin shallowly emarginate, the posterior broadly 

 rounded ; lateral lobes very much deeper than broad, the posterior sinus shallow,
