This iine species, although described so long ago as 1862, by Dr. Behr, from a 

 sino-le male which liad been received by him from some member of the State 

 Geological Survey, had remained otherwise unknown mitil 1874, no other speci- 

 men having been taken, and no knowledge existing of its locality. During the 

 past season Mr. James Behrens re-discovei'ed the species at Soda Springs, in 

 northern California, and from him I have received the pair figured on the Plate.
