 the larger head, the more distant eyes, the less sloping front, and in the 

 smaller number of joints in the antennae, these having but twelve joints, while 

 in Tettix there are thirteen or fourteen, generally the latter; and here the 

 joints are cylindrical instead of being flattened, and more swollen than in 

 Tettix. The maxillary palpi in Tettix have the fourth joint cylindrical, very 

 slightly largest at the apex, and the fifth cylindrical and slightly swollen, while 

 here the fourth is somewhat larger at the apex than at tiie base, broadly but 

 faintly ridged outside, and t4ie fifth swollen considerably, especially on the 

 anterior border, with a broad faint ridge outside. It differs also in the more 

 swollen and crested summit of the head; in having the lower posterior lobes 

 of the sides of pronotum thrust downward and outward, but slightly backward, 

 and the lower anterior angle rounded; in having a very high arched median 

 carina on the pronotum, and the lateral carinse only indicated in front; in 

 having the front border of the pronotum thrust forward over the head a little ; 

 in having on the prosternum only a broad, shallow, rounded, transverse hollow-
