femoral bars ami fine abdominal maculations, all combining to give 

 numerous color schemes of browns and grays. A few specimens are 

 reddish and others rather blackish.

As is usual in this species a great amount of individual color varia- 

 tion is present in the above series. In some specimens the pale dorsal 

 line is almost obsolete, in one completely lacking, in others, particularly 

 males, strongly marked. The tegminal maculations are of variable 

 intensity, in two specimens being extremely weak, while the dark 

 femoral bars and pale ventral section of the lateral lobes of the pro- 

 notum are subject to equal variations, but as a rule the femoral bars 

 are distinct in the individuals with a well contrasted color pattern.

The above series contains specimens extremely close to S. shoshone, 

 and the author inclines strongly toward the belief expressed by Mr. 

 Caudell that venusta is probably a form of shoshone}* Both sexes of 

 this form vary considerably in size, and in some individuals the meta- 

 zona is distinctly bullate dorsad instead of nearly plane as in the 

 majority. The color of the caudal tibia) varies from glaucous and 

 purplish pink to very dull purple.

This series is fairly uniform in coloration, such variation as is present 

 being in the shade of browns and yellows which make up the base colors. 

 The postocular bar is more distinctly marked in some specimens than 

 in others, while in some individuals the black lateral bars of the prozona 

 are slightly broken caudad of the yellowish oblique bar. The caudal 

 tibise vary from pinkish red to deep chrome yellow.
