Out of print, but worth finding if one is interested in beetles. (Bioquip had a few still in stock in 2003.) Almost 1,000 (black-and-white) illustrations, and some life history information. Papp's scratchboard llustrations are excellent, even artistic.

Note: I do not know how many of the illustrations and species accounts of this work are included in Papp's A Comprehensive Guide to North American Insects--there could be considerable overlap. I have not seen the latter work.
