 a pair of wedge-shaped black spots close together just iu front of 

 the median groove, a narrow pale median line between tlese which 

 is sometimes continued forward as far as the plane of the posterior 

 eyes, and generally backward around the median groove to the 

 posterior end of the thorax ; on each side a curved yellow line 

 extends from the posterior eye backward to the wedge-shaped spot 

 of the corresponding side, the space enclosed by these two lines 

 being oval and widest behind and redder than the rest of the 

 cephalothorax ; the extreme margin of the thorax black, on each 

 side a more or less distinct, broad, yellowish submargiual band, 

 sometimes broken into large spots, and with yellow bands radiating 

 from it to the median groove ; a small black mark at the posterior

 whole dorsum is much darker, the yellow and black markings very 

 obscure, while on the posterior half are 4-5 pairs of small white 

 spots. Sides of the abdomen brownish. Venter with a yellowish 

 or yellowish-brown mark extending in front from the lung slits, 

 where it is as broad as these, backward to the spinnerets where it
