This series shows some variation in size in both sexes, and also in the 

 shade of the general coloration. Some individuals are decidedly 

 blackish brown and others are practically ferruginous, the average, 

 however, being darker. The tegmina of the females in no case exceed 

 twenty-four millimeters in length.

Allied to 0. media and obtusa (Stal) from Brazil, but with the teg- 

 mina and wings much longer, the limbs also somewhat longer, while the 

 general size is about the same. The proportions of the exposed sec- 

 tion of the wings is as in obtusa, and the eyes are rectangulate laterad as 

 in that species. The relationship is apparently closer to obtusa than to 

 media. 



General size rather large. Head depressed, very broadly trigonal, 

 occipital outline straight, cephalic section of the occiput flattened, 

 except for four spaced longitudinal depressions, and forming an obtuse 

 angle with the portion of the head ventrad of the insertion of the 

 antennae; ocelli very small, well spaced in a broad unequal triangle; 

 facial scutellum transverse, the dorsal margin straight mesad and
