Family LI. SPONDYLIDyE. 



The Aberrant Long-ijorned Beetles. 



This family comprises l)nt four known Nortli American species, 

 closely allied to the true lono-horned booties of the next family, but 

 differing in the form of tarsi and structure of antenna?. They have 

 the antenna' short, the scape very shoi-t, uuicli constricted at base, 

 inserted at the sides of head near the base of the mandibles, the 

 second joint rather lariic, though snuiller than third; mentum 

 transverse ; elytra parallel, rounded at tip, covering the abdonu'n, 

 the latter with five ventral segments; legs rather short, compressed; 

 tarsi 5-.jointed without bi'ush or hairs beneath, the fourth joint dis- 

 tinct, fifth long, with slender claws. 



The name Spondjjiis. that of the tyi)ical genus, is derived from 

 a Greek w(u-d meaning "a verteV)ra joint," and was probably ap- 

 plied by Fabricius on account of the joints of the antennte having 

 deep pits or grooves on one side, in which organs of special sense 

 are supposed to be located. The North American s]K^cies live be- 

 neath bark, ])i-incipally that of ]une. Tlie family is divided into 

 two subfatiiilies, ono of wliich is represented in Indiana by the 

 single genus :
