The family is subdivided by Casey into six tribes, five of which 

 are represented in the State. 



KEY TO INDIANA TRIBES OF ANTHICin.E. 



(i. Abdomen composed of live free segments; tarsus (except in Mccyno- 

 tarxiiN) with tlie next to last joint lobecl beneath; tibial spurs gen- 

 erally distinct; labial palpi minute. 

 /(. Neck wide; eyes large, finely faceted and generally emarginate; size 



larger, (5-15 mm. 



c. Tarsal claws simple or slightly dilated at base; thorax constricted 



near apex. Tribe I. EURYGENIINI. p. l.".l!7. 



re. Tarsal claws with a broad basal tooth on the inner side at base. 



its apical part abruptly bent; thorax not constricted near apex. 



Tribe II. TEDIUM, p. 132!). 

 bit. Neck narrow; eyes not emarginate; thorax constricted at apex; 



smaller, less than 5 mm. 



(1. Eyes large, oval, rather finely granulate ; basal segment of abdo- 

 men elongate ; hind coxje close together ; tarsal claws with a 

 broad basal tooth. Tribe III. MACRATRIIXI. p. 13M2. 



<1d. Eyes small, rounded, generally coarsely granulated; basal segment 

 of abdomen not elongated; hind coxa? somewhat distant; tarsal 

 claws simple. Tribe IV. ANTHICINI, p. l."M.">. 



mi. Abdomen composed of four free segments, the first or basal one formed 

 of two firmly united but with the suture sometimes evident; tarsi 

 with the second joint from last lobed beneath; tibial spurs obsolete; 

 labial palpi with the last joint large and more or less dilated. 



Tribe V. XYLOPHILINI. p. l:>43. 



Tribe I. EUKYGENIINI. 



Elongate beetles, clothed with gray pubescence and having the 

 mandibles broadly truncate at tip; maxillary palpi dilated; next to
