A large number of other periodicals devoted to entomology have been issued, principally in Europe, but after continuing for a year or more their publication has been abandoned, and they are not included here. Important entomological papers have also been published in many serials devoted to zoölogy or the natural sciences generally. Among them may be mentioned the following:
