KEY TO INDIANA GENERA OF HIPPODAMIXXT. 



a. Tarsal claws simple (Fig. 184, /) ; body oval: hind angles of thorax ob-

 aa. Tarsal claws either with a large tooth at base or bifid: length 4.5 mm. 

 or more. 



I). Claws with a large epiadrate basal tooth ( Fig. 1S4, e) ; thorax with a 

 narrow but distinct margin along the base. II. Megilla.
