Notes on the Earwigs (Dermaptera) of North 

 America, north of the Mexican Boundary. 



By MORGAN HEBAKD, Philadelphia, Pa. 



The Philadelphia collections contain material of all the 

 species of Dermaptera native to, or adventive in, these regions. 

 It is the purpose of the present paper to list th'e native species, 

 giving their synonymy and in each case the first incorrect 

 use of a name for the species based on material from the re- 

 gions here considered; to record hitherto unreported material 

 before us, and to give briefly the local habitat and known dis- 

 tribution of each species. One new species is described. The 

 nomenclature shows but little recent change ; annulipcs hav- 

 ing been transferred by Burr from Anisolabis to Euborellia. 

 while the series now at hand prove beyond question the dis- 

 tinctness of the species of the Unidentata Group of the genus 

 Prolabia found in Hayti and in the southeastern United 

 States, the correct name for the latter insect being pulchclla 

 of Serville. 



Though the different North American species have been 

 frequently mentioned in the literature, few studies in any 

 way comprehensive have appeared. 1 



The order is but weakly represented in the regions here 

 treated, except in the subtropical and tropical areas of the 

 southern United States, and constant field work has been nec- 

 essary to assemble even the small total here recorded. 



Fifteen species are represented, of which four may be said 

 to be confined in distribution to the restricted tropical areas 



l Oi these the most important are:
