Cephalothorax brown with three buff lines running back from the 

 eyes and uniting into one at the dorsal groove, also a subniarginal 

 band on each side. 



Abdomen with a median light stripe bordered with black, on the 

 anterior portion, and outside of this, several pairs of yellowish spots 

 becoming smaller and united by cross lines posteriorly, (when dry 

 there are two longitudinal rows of small white dots on the back 

 and some white markings on the sides and anterior margin) rest of 

 abdomen blackish. Below buff with three black lines from the epi- 

 gynum to the spinnerets, the side ones more or less contiguous with 

 the dark coloring of the sides of the abdomen. Legs yellowish ; the
