HAB. Souoran Eegiou, Western Texas. 



This species is rather rare in New Mexico and Arizona ; it resembles 

 H. maculata somewhat, but may readily be distinguished from it by its 

 larger size and more elongated tail, as well as by marked other specific differ- 

 ences. Two lateral spots represent the abdominal crescents in the female.
