Aboil t 161 species of Clerida*, belonging to 27 genera, are known 

 from America north of Mexico. Of these 28 species and one va-

This tribe, which contains more than two-thirds of the Indiana 

 species, is sufficiently characterized by having the fourth joint of 

 the tarsi about equal in size to the third and the Hanks of thorax 

 continuous with disk; middle coxa 1 scarcely prominent, moderately 

 distant, except in II>i<inf>c< ra, where they are but slightly sepa-
