Superfamily Argiopoidea 



found in Florida, of which only the male is described. This is 

 the Eilica bicolor of Banks. 



Genus SERGIOLUS (Ser-gi'o-lus) 



The cephalothorax is narrow, oblong, slightly convex, a little 

 narrowed in front, and without a median furrow. The anterior 

 eyes are close together, in a straight line, and with the median larger 

 than the lateral eyes. The posterior eyes are small, in a slightly re- 

 curved line. The median ocular area is trapeziform, and a little 

 longer than wide. The clypeus is at least twice as wide as the an- 

 terior eyes." The chelicerae are of moderate size, with the margins 

 of the furrow unarmed; the lower margin indistinct, the upper sin- 

 uous and hairy. The labium is nearly three times as long as wide 



Three species occur in the United States. 



Sergiolus variegatus (S. va-ri-e-ga'tus). — This brightly col- 

 oured species is easily recognized by the markings of its abdomen. 

 The cephalothorax is bright orange, a little darker toward the 

 eyes. The abdomen is black with three transverse white stripes 

 and a T-shaped white mark between the first and second stripes. 

 The female is one fourth inch in length. 



This is a very widely distributed species. 



Sergiolus bicolor (S. bi'co-lor). — The length of the body of 

 the female is one third inch. The cephalothorax and legs are 

 reddish yellow; the basal half of the abdomen pale gray, the apical 

 half and spinnerets, jet black; the ventral aspect of the abdomen 

 is pale gray except the apical two fifths, which is black, but broadly 

 indented by the gray in the middle. 



This is a southern species. 



Sergiolus cyaneoventris (S. cy-an-e-o-ven'tris). — The cephalo- 

 thorax is bright yellowish red. There is a white band across the 

 base of the abdomen, and one across the middle. Between these 

 white bands the abdomen is shining brown; and behind the middle 

 band it is iridescent black or greenish. The venter is bluish black. 



This species is found in Florida.
