Superfamily Argiopoidea 



In the female the ocular quadrangle is either entirely black 

 or with the three sides occupied by the eyes black; the remainder 

 of the cephalothorax is light brown with three, more or less distinct, 

 longitudinal dark bands (Fig. 762); on the lateral and posterior 

 edge of the thorax there is a narrow black line. On the abdomen 

 there are two longitudinal red bands and indistinct chevrons of 

 the same colour in the middle of the hinder half. In alcohol the 

 red marks change to brown. 



The typical male resembles the female; but the red bands 

 on the abdomen are broken up into two rows of spots which are 

 connected with the chevrons (Fig. 763). 



In the black male both cephalothorax and abdomen are black; 



1 -62.

but there is a pale spot in the centre of the thorax which is divided 

 by a longitudinal black line. In the middle of the ocular quad- 

 rangle there is a transverse row of three prominent tufts of hairs. 



Genus ONONDAGA (On-on-da'ga) 



The cephalothorax is low and nearly flat, with a transverse 

 groove behind the dorsal eyes; the sides are a very little dilated 

 behind the dorsal eyes, nearly vertical in front, rounded behind; 

 the cephalic part is inclined and the thoracic part falls slightly 

 in the first half, then more steeply. The eye-region occupies less 

 than half of the length of the cephalothorax, and is slightly wider 

 behind than in front; the second row of eyes is a little nearer the
