to those boxed in turpentine operations. The riddling of the trunk by 
the worm holes spoils the use of the wood for lumber and often shortens 
the turpentine crop because the weakened trunk can not support the 
crown during the heavy winds and is broken off. Dr. A. D. Hopkins 
was the first to discover and record the habits of this species which 
he listed as the turpentine borer in bulletin 48 of the Division of 
Entomology. 
THE EUROPEAN EARWIG, FORFICULA AURICULARIA LINN. 
By E. O. Essia, University of California, Berkeley, Calif. 
The European earwig has been known for several years in the eastern 
part of the United States 1 and it may be of interest to know that it also 
occurs in the northwestern part, having been received in considerable 
numbers from Seattle, Washington, September 16, 1916. The speci¬ 
mens were sent by express and confined alive in a jelly glass packed in a 
small wooden box so that the top of the glass, which was held in place 
by ordinary wrapping twine and punched full of holes so that the in¬ 
sects would not smother in transit, was exposed. The specimens, 
some fifty in number and representing both sexes, arrived in Berkeley 
in splendid condition, not a single one being dead, and is a fine example 
of how insects may become accidentally established in new territory. 
Packed as the glass was it is remarkable that it came through without 
being broken and we may be thankful that the colony was not thus 
turned loose to repeat, in California, what it is doing in other places. 
At Seattle it is reported as being abundant in houses and very de¬ 
structive to roses in the garden. 
In Denmark it has proved destructive to Cauliflower. 2 
Knowing that it is so close to our state we should all be on the alert 
to prevent its entrance and to caution collectors and the general public 
regarding the menace.
