ON A COLLECTION OF ORTHOrTERA FROM SOUTHERN 

 ARIZONA, WFTH DESCRIPTIONS OF NEW SPECIES. 



By Andrew Nelson Caudell, 



Of the Department of Agriculture. 



The majority' of the Orthoptera here noted were taken by E. J. Oshir, 

 mostly in the Huachuca Mountains, during- the summer of 1903. A 

 few other species have been added, l)ut where not otherwise mentioned 

 the specimens were collected by Oslar. All the specimens are now 

 deposited in the United States National Museum. 



SPONGOPHORA APICIDENTATA, new species. 



One male, one female, Tucson, Arizona, January 14, on giant cactus, 

 by H. G. Hubbard. 



Des<2r'(ption. — In size and oeneral appearance very like S,. hrumiei- 

 pennis^ the female being practically indistinguisha- 

 ble from that species. The males, however, differ 

 quite decidedly from hranne/penru!^ in the form 

 of the forceps, which are shorter, more incurved, 

 and armed with a single tooth, near the apex, and 

 by having the pygidium wider and more broadly 

 concave apically. Lateral folds of the abdomen, 

 as in hruniiequmius. The antenna^ seem to con- 

 sist of but fourteen segments, but some of them 

 may be missing. 



Length, male, 9 mm.; female, 8 mm.; forceps, 

 male, ?> mm.; female, 3 mm.

Besides the types, I have seen six males and 

 one female from the same place, taken under the 

 same circumstances, one male and two females 

 from Los Angeles and San Diego counties, Cali- 

 fornia, as well as several females, probably belong- 

 ing here, from Catalina Springs and Fort Yuma, 

 in Arizona, and a few taken under old leaves near Columbia, Texas. 



The apparently fourteen segmented antenna^ would .serve to locate
