Family LI. SPONDYLID^. 



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 antennas. They have 

 the antenn* short, the scape very short, much constricted at base, 

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

 second joint rather large, though sinaller 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 S'poiidylis. 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 antennce having 

 deep pits or groo^-es on one side, in whicl\ organs of special sense 

 are supposed to be 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 :
