Family LYMEXYLIDiE. 



Only a single species, brown in color, very long, s'ender, cylindrical, taper- 

 ing posteriorly and covered with a very fine silky pubescence, [t is very rare as 

 an adult, though the larva, or the very slender, irregular boring which it makes 

 in old oak wood, is more frequently seen. A European species, L. navale, has 

 been extremely destructive to ship timber, and some damage is done by this or 

 an allied species in our Southern States ; in New Jersey no injury has yet been 

 caused.
