 CYCLOSA BIFURCA 



of Cyclosa in our fauna. The abdomen is long; the basal half 

 bears two pairs of humps; the caudal half is more slender and is 

 bifurcate at the tip (Fig. 465). The body is green mottled with 



white; there is a light wavy band on the 

 side of the abdomen; and the abdomen is 

 bordered with a black line above, back of the 

 humps. On the ventral side of the abdomen, 

 there is a bright red spot between the epigas- 

 tric furrow and the spinnerets. The legs are 

 banded with reddish brown. 



I found this to be a common species 

 near Miami, Fla. I first found it in the 

 jungle near the shore of the bay, where 

 it made an orb-web with a string of egg- 

 sacs across it like a stabilimentum. Later 

 1 found it to be a pest at the cottage 

 connected with the Sub-tropical Laboratory. There it built its 

 webs on the ceiling of the veranda and there strings of egg-sacs 

 hung from the ceiling by the hundred; and at the lower end of 

 each string of egg-sacs there was a spider. 

 One of these strings is represented by Fig. 466. 

 Cyclosa turbinate (C. tur-bi-na'ta). — ■ 

 This species of Cyclosa isdistributed through- 

 out the United States; but I have found it 

 much more common in the South than in 

 the North. The female can be easily dis- 

 tinguished from the other species of Cyclosa 

 occurring in our fauna by the shape of the 

 abdomen (Fig. 467). The abdomen bears a 

 pair of dorsal median tubercles and is pro- 

 longed into a slender caudal projection. In 

 the male the abdomen is rounded and is 

 marked above at the base with a transverse 

 white band, which is sometimes interrupted 

 in the middle, and a pair of white spots in 

 front of the middle of its length. 



This is the Epeira caudata of Hentz. 



Cyclosa walckenceri (C. walck-e-nae'ri). — This is a tropical 



species whose range extends into the southern part of the United 



States. It can be distinguished from our other species by its
