BRITISH COLUMBIA DERMAPTERA 



Order DEKxMAPTEKxV 



(Tlie Barwit>-s) 



We may describe the Earwigs as:*" Insects with slight post-emln-y- 

 onie development, the nymphs being very similar to the imagines. The 

 hind femora are suitable for running, the tarsi ])eing of three segments 

 usually without pulvillus. They are mute, stridulating organs being 

 absent. Their bodies are elongate, the arrangements of the segments of 

 the abdomen being imbricate and the abdomen being terminated by 

 cerei, which take the form of callipers. The elytra are leather-like and 

 much smaller than the wings, these latter being folded from the base 

 and again in the middle of the anterior margin; many species, however, 

 are wingless. Ocelli are absent." 



The fallowing ai-e tlie records of British Columbia Earwigs: 



Euborellia annulipes Lucas, 1847. The Red-legged or Banded Ear- 

 wig. Lucas. Ann. Soc. Ent. France, (2), vol. 5, p. LXXXIV (1847). 



In the Vernon Entomological Laboratory collection there are two 

 earwigs collected by Mr. R. C Treherne, of the Dominion Entomological 

 Brancli, on the S.S. Talthybius — a Blue Funnel liner — while this ship 

 was in the Vancouver docks. They were taken in February, 1916. Au 

 examination of these specimens showed that one is a female Forficula 

 auricularia Tjinnaeus, and the other a female Euborellia annulipes Lucas. 



Euborellia annulipes Lucas is a dark colored wingless species, it is 

 cosmopolitan, being practically a universally distributed species. This is, 

 I believe, the only Canadian record of this insect; it lias been recorded 

 from Massachusetts by A. P. Morse and from Connecticut.

Labia minor Linnaeus, 1758. The Little Earwig. (Introduced). 



Linnaeus, Carl von. 'Syst. Nat., p. 423 (1758). 



This small earwig is common throughout Europe. It has been in- 

 troduced into America where it now seems to be firmly established. It 

 flies freely in the sunlight. It is not common in British Columbia.

Forficula auricularia Linnaeus, 1758. The Common European Eai"- 

 wig. (Introduced). 



Linnaeus, Carl von. Syst. Nat., p. 423 (1758). 



This is the common Earwig of Europe. It has, like Labia minor, 

 found its way to America and is now sufficiently numerous in some parts 

 of the United States and Canada to cause considerable annoyance and 

 damage. I am informed by Mr. R. C. Treherne, Chief, Division of Field
