This no doubt belongs in the genus Uptioles Walck., or Mithras Koch. 

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

 Found in pine woods among dead branches, which 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. 265.

Sub-genus Prodidomus. Mihi. 



Characters. Eyes eight, placed near together ; four in [467] 

 front, making a straight row, two on each side, forming a curve 

 with the external ones of the first row, and leaving a space above; 

 external ones sub-oval, two middle ones round and black ; max- 

 illce triangular, wide at base, pointed at tip ; cheliceres very 

 large, fangs long and bent; feet J/.- 1- %• 3. 



Observations. This new sub-genus shows some of the char- 

 acters of Clubiona and of Theridion. I hope some future 

 naturalist will give its history and its location in the natural 

 arrangement. I know nothing of its habits.
