Nomina Insecta Nearctica
was originally published in a series of 4 rather large volumes. Each of the volumes have now been broken down into separate volumes, making downloading easier and faster and also allows you to take only those particular segments of the checklist of interest to you. Additionally, superfluous pages (blanks and title pages) have been eliminated.
- Coleoptera, Strepsiptera
- Hymenoptera, Mecoptera, Megaloptera, Neuroptera, Raphidioptera, Trichoptera
