Superfamily Argiopoidea 



web has not been described. Simon states that they carry their 

 egg-sacs attached to the spinnerets like Lycosa. Two species 

 occur in this country. 



Theridula opuknta (T. op-u-len'ta). — The female of this 

 species (Fig. 357) is easily recognized by its portly abdomen, 

 which is high and wider than long; it is yellowish gray, with a

greenish white spot in the middle and a black spot on a slight 

 elevation on each side; the cephalothorax is yellow with a wide 

 black stripe in the middle. The length of the body is one tenth 

 inch. 



In the male the abdomen is not so greatly widened and the 

 markings are indistinct; but the cephalothorax bears a con- 

 spicuous, broad, dark, longitudinal band as wide as the eye-space. 

 The length of the body is one twelfth inch. 



This is a very widely distributed species. It is the Theridion 

 sphccrula of Hentz. 



Theridula quad ri punctata (T. quad-ri-punc-ta'ta). — This 

 species is found in the extreme South. The cephalothorax is 

 marked with a broad band as in the preceding species; the 

 abdomen is black with four oval, white or yellowish spots 

 above. It measures one tenth inch in length. I have seen only 

 the female.
