the sea). They may be safel}- kept in this way for a few months, but if 

 subjected to prolonged immersion they are ruined by the marine worm 

 {Teredo navalis). To avoid this an experiment was recently made in 

 the dry storage of logs, which has, however, proved unsuccessful, the 

 logs having been attacked by a small beetle which tunnels through the 

 sapwood, penetrating more or less into the heart-wood. The damage 

 done by the borings of this insect is not really very serious, . as the 

 tunnels do not as a rule penetrate more than about half an inch into the 

 heart-wood ; but the sapwood is riddled b}- the borings, and the hearL- 

 wood usually shows the holes on its surface, which detract from the appear- 

 ance and market value of the los:."

So far as is at present known this insect would appear to have the 

 same habits as X. adiiinbratiis described above. Both species were identi- 

 fied by Colonel Winn Sampson.
