KEY TO INDIA^'A TRIBES OF ANTHICID.E. 



a. Abdomen composed of five free segments; tarsus (except in Mccijno- 

 tar.sus) with the next to last joint lobed beneath; tibial siiurs gen- 

 erally distinct; labial palpi minute. 

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

 larger, 6-15 mm. 

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

 near apex. Tribe I. Eurygexiixi. i>. iy2T. 



cc. Tarsal claws with a broad basal tfioth on the inner side at base. 

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



Tribe II. Pedilixi. p. 1.32!l. 

 hi}. Neck narrow ; eyes not emarginate ; thorax constricted at ai;>ex ; 



smaller, less than 5 mm. 

 ■ d. Eyes large, oval, rather finely granulate; basal segment of abdo- 

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

 broad basal tooth. Tribe III. JIacbateiixi, p. 1.3.32. 



fid. Eyes small, rounded, generally coarsely granulated; basal segment 

 of abdomen not elongated; hind coxEe somewhat distant; tarsal 

 claws simple. Ti-ibe IV. Axthicixi. p. 133.3. 



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

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

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



Tribe V. Xylophilini. p. 1343. 



Tribe I. EUKYGENIIXI. 



Elongate beetles, clothed with gray puliescence and having the
