DRYOBIUS. 
D. sexfasciatus Say. 
This is one of our most beautiful and graceful species. In 
former years it was abundant, but is now rare. Its larvze bore in 
beech and maple. I have trapped them by nailing slabs of loose 
bark on the dead tree trunks, and visiting them every few days. 
Holding an inverted umbrella under the slab, to catch the beetles, 
when the bark was disturbed as they would drop to the ground. 
June and July.
