Family LJ. SPONDYLIDyE. 

 THE ABERRANT LONG-HORNED BEETLES. 



This family comprises but four known North American species, 

 closely allied to the true long-horned beetles of the next family, but 

 differing in the form oF tarsi and structure of antennae. They have 

 the antenna 1 short, the scape very short, much constricted at base, 

 inserted at the sides of head near the base of the mandibles, t la- 

 second joint rather large, though smaller than third; mentum 

 transverse ; elytra parallel, rounded at tip, covering the abdomen, 

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

 tarsi 5-jointed without brush or hairs beneath, the fourth joint dis- 

 tinct, fifth long, with slender claws. 



The name Spondylis, that of the typical genus, is derived from 

 a Greek word meaning "a vertebra joint," and was probably ap- 

 plied by Fabricius on account of the joints of the antenna? having 

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

 are supposed to bo located. The North American species live be- 

 neath bark, principally that of pine. The family is divided into 

 two subfamilies, one of which is represented in Indiana, by the 

 single genus:
