Casey mentions Indiana as one of the localities from which his 

 specimens came. Horn states tliat it occurs "everywhere east of 

 the Rocky Mountains." I have not seen it from the State. The 

 mature beetle is said to bore for feeding purposes in living twigs 

 of fruit trees and grape vines, never, however, ovipositing in such 

 twigs, liut living as larvfe in the dead and dry wood of forest trees. 



V. DiNODERUs Steph. 1880. (Gr., " huge + neck.") 



Species of cylindrical form having the tarsi short, the four basal 

 joints each about the same length and together nearly equal to the 

 fifth. The declivity of the elytra is normallj^ convex, though some- 

 times flattened. Four of the eight known species may occur in In- 

 diana, though but two of them have been taken.
