Yuma county, Arizona. September, 1903. One male. Coll. Mor- 

 gan Hebard. 



This specimen probably belongs to this genus and species, but several 

 characters, such as the proportions of the prozona and metazona, do 

 not agree with the description. These parts are said to be "of sub- 

 equal length," while in the specimen at hand the metazona is decidedly 

 shorter than the prozona. Generally, however, the specimen agrees 

 very well with the description. 



Gomphocerus clepsydra Scudder. 



Truchas Peak, Rio Arriba county, New Mexico. 13,000-14,000 feet 

 elevation and above timber line. August 2, 1902. (W. P. Cockerell.) 

 One male, two females. 



I am not prepared to make any critical remarks on the standing of 

 the several American "species" of this genus, and accordingly the use 

 of clepsydra as a full species should not be considered an expression of 

 opinion, but simply the utilization of a term to designate a type the 

 validity of which is, to say the least, doubtful.

LigurotettixSkunzei Caudell. 



Florence, Pinal county, Arizona. July 1, 1903. (C. F, Biederman.)
