38 TWENTY-EIGHTH REPORT ON THE STATE MUSEUM. 
when arrived at their perfect state they migrated in 
swarms like bees into Suabia and Franconia. At length be- 
tween 1784 and 1789 in consequence of a succession of cold 
moist seasons the numbers of this scourge were sensibly 
- diminished, but they appeared again in 1790 and so late as 
1796 there was great reason to fear for the few fir trees that 
were left.’ 
Westwood states that occasionally the evil was so great that 
prayers were offered in the churches against its extension. 
While we hope that our spruce tree bark-borer may never 
prove to be such a pest as this Tomicus, we certainly think 
that he deserves some special attention.
