AMERICAN ORTHOPTERA. 261 



anal field elongate pyriform, the anal sulcus being gently curved. Wings nar- 

 row, sub-acuminate ; anterior ulnar vein with two branches which originate at 

 or before the middle of the vein. Supra-anal plate produced, at the base 

 expanded into lateral plates which extend over and embrace the bases of the 

 cerci, the central portion extended and apically rotundate. Subgenital plate 

 broad, spoon-shaped, the apex moderately emarginate. Cerci rather long, 

 depressed, acuminate. Anterior femora equalling the coxae in length, inferior 

 margin in the apical half closely set with spines; tibiae with the spines on the 

 superior margin distributed in two rows, 2 exterior, 3 interior; metatarsi but 

 slightly shorter than the remaining tarsal joints. Posterior femora slightly shorter 

 than the tibiae ; tibiae with the spines of the upper surface in three rows; meta- 

 tarsi half again as long as the remaining joints of the tarsi. 



General color pale orange and black. Head orange red ; eyes chestnut ; palpi 

 black ; antennas with the basal plumose section black, then a baud of dull yellow, 

 and the remaining portion black. Pronotum orange red. Tegmina with the 

 basal two-fifths pale orange, the remaining section black. Wings' with the por- 

 tion covered by the light section of the tegmina pale orange, the remainder 

 black, all the tints being weakened by the sub-hyaline character of the wings. 

 Abdomen above black, the supra-anal plate the same color. Under surface 

 orange red; tibiae, tarsi, apical portions of the femora and apical portions of the 

 anterior coxte black ; trochanters with a blackish spot. Cerci with the basal 

 half black, the apical section yellow.
