This species, recently descril^ed from Sonora(?) and Mazatlan, 

 Mexico, was considered by the describer to possibly reach "south- 

 western Arizona in the vicinity of the Huachuca ^Mountains," an 

 opinion which the present material well sustains. In size the adults 

 in this series are fairly uniform, only one male l^eing slightly smaller than 

 the others, while the coloration is distinctly more uniform than usual 

 in series of this genus. As the male sex was not in the possession of the 

 describer, the measurements of an average male may be of inteiest: 



Length of body, 41 mm. 



Length of pronotum 11.5 " 



Caudal width of dorsum of pronotum, 7.7 " 



Length of tegmen, 7.8 " 



Length of caudal femur, 25.5 "

This series exhibits considerable variation in size in both sexes, and 

 also some difference in the length of the metanotum and the character 

 of the caudal angle of the same. In color numerous variations are 

 observed, hardly two specimens appearing exactly the same; variation 

 in base color, washes, pronotal margining and maculations, as well as 



" By the acquisition of new material and the re-examination of old the author 

 has been compelled to modify his opinion expressed in 1902 {Proc. Acad. Nat. 

 Sci. Phila., 1902, pp. 595-597) regarding the synonymy of species of this genus. 

 Thomas's magnus is distinct from tshivavensis, as is also Bruner's robustus. 

 The specimens recorded from El Paso, Texas, Alamogordo, Otero Co., and Lake 

 Valley, Sierra Co., New Mexico, are of the latter species.
