This interesting species was first described from specimens brought 

 from New Mexico by Dr. T. C. Henry, of the United States Army, since 

 which time, so far as is known, it has not been seen until collected by Dr. 

 J. T. Rothrock and H. W. Henshaw, of this expedition in 1874. The 

 locality where the specimens were taken is Rock Creek Canon, south of 

 Camp Apache, Ariz., and they were secured while fishing in a small stream 

 which runs through the canon, the animals taking the bait fiercely and freely, 

 appearing to be numerous. It is a matter of some surprise in view of this 

 abundance that the species has not been recognized for so long an inter- 

 val. The plate affords a view of this species from above and below and 

 in profile.
