ORTHOPTERA 



269 



Family HEMIMERID^ 



Further studies of this family during the 

 years since the pubHcation of former editions 

 of the Introduction seem clearly to have estab- 

 lished the affinity of the Hemimeridae with the 

 order Dermaptera. Recent explorations and 

 collections from rats of Africa have brought 

 to light several new species in the family and 

 much additional knowledge concerning their 

 habits. We have, therefore, placed the family 

 with a brief discussion of it under the Dermap- 

 tera, on page 463. In 1925 Professor Comstock 

 said concerning this family, "although these 

 are exotic insects, they are mentioned here on 

 account of their exceptional manner of devel- 

 opment and mode of life." The additional 

 knowledge concerning them emphasizes this 

 observation and justifies retaining a brief 

 discussion of the family among its proper 

 relatives.
