Texas, Arizona, and Colorado river of California: lives in species of Prosopis. The last 
ventral segment is provided with a submarginal elevated serrate line, and a smooth an¬ 
terior triangular spot each side, which projects into an acute tooth: the segments of the 
abdomen are each furnished with a smooth lateral spot, and their posterior angles project 
strongly. The tooth of the anterior femora is serrate externally, but scarcely so inter¬ 
nally: the third joint of the antenna) is more than twice as long as its width.
