1014 FAMILY L1I. CERAMBYCIIXU. 



KEY TO TKIBES OF CALUDIOIDES. 



(i. Ligula horn-like; eyes variable: second .joint of antenna? more than one- 

 thinl as long as third. Tribe I. ASEMINI. p. 1014. 



(id. Ligula membranous; eyes finely granulate; second joint of antenna? not 

 more than one-third as lung as third. 



Tribe II. CAI.I.IIHIM. p. H>1<>. 



Tribe I. ASEMINI. 



In this tribe the antenna' an- densely punctured and puhescent. 

 with the second joint nearly halt' the length of third and the llth 

 simple; front coxa? transverse, with distinct trochantin, the cavities 

 open behind; scutellum rounded behind; males with fifth ventral 

 segment transverse and sixth segment visible ; females with fifth 

 segment prolonged, sixth invisible. In this and many of the fol- 

 lowing tribes the character of the granulation of the eyes is much 

 used in separating the genera. In those which are "coarsely gran- 

 ulate" the lines between the facets are deeply impressed. In the 

 second group the granulations are much finer, the lines feebly im- 

 pressed, the surface of the eye appoarinu 1 almost plane. Repre- 

 sentatives of three of the seven genera comprising the tribe have 

 been taken in the State, while those of another probably occur. 



KKY TO INDIANA (.; 10 M<:RA OF ASEMINI. 



(/. Color black or dark brown; form cylindrical, scarcely depressed; opi- 



mera of mesothorax truncate at inner end. 

 1>. Eyes not wholly divided, often deeply emarginate. 



c. Eyes moderate in size, transverse, finely granulated and hairy; an- 

 tenna? finely pubescent. ASEMT.M. 

 cc. Eyes large, coarsely granulated, not hairy. IV. CRIOCEPHALI s. 

 1>b. Eyes divided, apparently four in number, rather finely granulated. 



V. TETROPirM. 



mi. Color pale yellowish; form depressed; epimera of mesothorax narrowed 

 and acutely pointed at inner end. VI. SMOUICUM. 



As( nnini Hin^hnii ITald ., black, opaque, thorax rounded at sides, 

 length VJ-15 mm., ranges from 'Lake Superior to Florida and 

 eastward." 



IV. CRIOOEPIIALI-S Muls. 1S89. (Or., "a ram + head.") 



This genus comprises seven rather large, suhcylindrical species, 

 having the eyes coarsely granulated, not hairy and the thorax with 

 two to four large and shallow depressions on the disk. One of the 

 seven has been taken in Indiana and another mav occur.
