the latter darker toward tip, no bands; abdomen black, two short narrow

Length 16 mm.; ceph. 6.9 mm. long, broad 5 mm.; tibia plus patella IV 

 7.1 mm. Cephalothorax pale yellowish or reddish, an irregular brown stripe 

 each side, terminating behind in a darker spot, the pale space of nearly equal 

 width throughout, but starting between the eyes as a white line; eyes on black

 apart. Legs of moderate length; three pairs of spines under all tibiae; stern-
