FAMILY XUI. — CLERIDiE. 



Wolcott. — "The North American Species of Chariessa," in Ent. 

 News, XIX, 1908, 70-72. 



About 161 species of Cleriche. belonging to 27 genera, are known 

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

 riety, representing 14 genera, have been taken in Indiana. LeConte 

 and Horn divide the family into two tribes, both of which are rep- 

 resented by species taken in the State. 



KEY TO TRIBES OF THE FAMILY CLERKLY. 



a. Tarsi with fourth joint of normal size; disk of thorax continuous with 

 the hanks. Tribe I. Clerixi. p. 848 



aa. Tarsi with the fourth joint very small and indistinct; disk of thorax 

 separated from the flanks by a marginal line. 



Tribe II. Exopliixi. p. S57. 



Tribe I. CLERIXI. 



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 flanks of thorax 

 continuous with disk; middle coxae scarcely prominent, moderately 

 distant, except in Hydnocera, where they are but slightly sepa- 

 rated; body always elongate. Of the 14 genera belonging to this 

 tribe eight are known from Indiana, while two others may occur. 



KEY TO IXDIAXA GEXERA OF CLERIXI. 



a. Five joints of tarsi visible from above. 



l>. Terminal joint of antennas as long or longer than the preceding joints 

 combined; elytral punctures confused; thorax with a discal black 



Spot. I. MOXOPHYLLA.

 length ; elytral punctures in rows, 

 c. Eyes finely granulated ; tarsal claws bifid at apex. Tillfs.

aa. Four joints only of tarsi visible from above, the first joint very small, 

 covered by the second ; tarsal claws toothed. 

 (1. Eyes emarginate in front.
