Theridinm Zelotypum, new. Specimen named by Keyserling iu Mus. Comp. 

 Zool., Cambridge, Mass. 



Plate I, figdrks 4, 4a. 



Of this large species I have only females. They measure 4'"™ or 

 more in length. The cephalothorax is orange with a distinct dark 

 stripe in the middle, and dark edges. The legs are orange, with brown 

 rings at the ends and indistinct rings in the middle of each joint. 

 The light stripe on the abdomen is distinctly herring-bone shaped, 

 with the corners running down the sides of the body dividing the 

 black stripes into several separate squarish spots. The middle of the 

 abdomen is bright red. Underneath there is a black spot under the 

 spinnerets, and the epigynum is brown. The epigynum has a single 

 opening outside, some distance from the edge. 



These spiders were found at Eastport and Portland, Me., Aug., 

 1872 and 1873, in spruce trees. The webs were large, supported be- 

 tween the branches by threads running upward to the branches 

 above and furnishing lodging for numerous specimens of Arygrodes 

 trigomini. The spider had usually a tent covered with dry spruce 

 leaves, under which it hung with cocoons and young.

 well concealed by its color. It is also found on the dried tops of wild 

 Spircp.a.
