Superfamily Argiopoidea 



cles are white, and the median eyes are ringed with white. The 

 abdomen is white or light yellow, with a broad transverse black 

 or brown band near the hind end (Fig. 609). This band usually 

 has a broad deep notch in the middle of the front margin, but it is 

 not always thus notched. There are usually two or three pairs of 

 small brown spots between this band and the base of the abdomen. 



This species is widely distributed; it is especially common 

 in the Southern Atlantic States. Hentz, who first described 

 the species, states that it is frequently found on the blossoms of 

 umbelliferous plants. 



Synema bicolor (S. bi'co-lor). — The female measures one fifth 

 inch or a little more in length. The cephalothorax is dark brown, 

 almost black, with a lighter line in the middle and a white line on 

 each side near the edge. The abdomen is light gray with indis- 

 tinct lighter lines at the sides and small light spots in the middle. 



This species is distributed from New England to Florida. 



Synema obscura (S. ob-scu'ra). — The male measures one 

 seventh inch in length. The cephalothorax is dark red, lighter 

 above, with a yellow seam on the lateral margins. 'The eye-space 

 is brownish yellow. The abdomen is blackish brown above, 

 with a narrow, white transverse band in front, the hind margin 

 of which is irregularly toothed; the venter is a little lighter brown, 

 and flecked with white, especially in front. 



The female has not been described. The male was described 

 from Mount Washington. 



Subfamily PHILODROMINiE (Phil-od-ro-min'ae) 



In this subfamily the tarsi of the first and second pairs of 

 legs are furnished with scopuke beneath, at least in the females 

 (Fig. 610). These scopulae can be easily distinguished from a
