Obviously the taxonomy is a bit dated, but the text has great discussions of many genera and subfamilies. I estimate roughly 500 detailed line drawings of antennae, tarsi, ventral details, etc.
"It contains an original, simplified, and completely-illustrated key for the identification of beetle families east of the Great Plains, a discussion of the appearance and habits of the various adult and larval forms, and a useful up-to-date  bibliography for each family."
