This no doubt belongs in tlie genus Uplioleif AValelc, or Mithras Koch. 

 It really has eight eyes, the front lateral pair being very small and colorless. 

 Found in pine woods .imong dead branches, Avhicli it much resembles in 

 color. The web and habits are described by Prof. B. G. Wilder, in Pro- 

 ceedings of the American Association for the Advancement of Science, 

 1873, p. 2C5.
