broad black spot underneath, with a yellow lunule on each side ; 

 feet, with joints terminated by a black band. 



Observations. The male and female were found very fre- 

 quently near streams, where they make perpendicular webs. 

 This spider during the day remains strictly concealed near its 

 web, in a dwellino; which it constructs with leaves drawn to- 

 gether in the manner of a tube by means of threads.

13. Epeira Thaddeus. 

 PI. 13, fig. 6. 



Description. Ceplialothorax rufous ; abdomen green, yel- 

 lowish towards the base, with a black band on each side of the 

 abdomen, piceous underneath, with a yellow spot in the centre ; 

 feet orange, varied with rufous and blackish. A somewhat 

 large species. 



Observations. This species, which is sometimes whitish on 

 the abdomen, is nevertheless very readily recognized. I have 

 seen some specimens larger than the delineation. Its dwelling- 

 place is really beautiful ; it is placed above its web, and made 

 of the finest white silk, shining with a satin lustre ; its shape is 

 that of an inverted thimble, and it is usually placed under a 

 leaf bent together for the pui'pose of affording shelter and 

 security. 



Habitat. Alabama. September, October. 



[A specimen was found in October, larger than the drawing, 

 PI. 13, fig. 6, but the abdomen was nearly white instead of 

 green. Supplement.'] 



14. Epeira hebes. 



PI. 13, fig. 7.
