A revision of the species of Cafius from the west coast of North America with notes on the east coast species
This is a great resource for identifying North American Cafius to species. Written in 1980 by H. E. Orth and Ian Moore.

The keys are straightforward, the descriptions well-written and detailed, and there are figures at the end of the article...including large, good-quality, dorsal-view line drawings for each of the 13 species covered, and drawings of antennae for 5 species and aedeagi for all 13. While the emphasis is on the 10 species known (in 1980) from the west coast, it also includes a key to the five east coast species, with briefer discussions of them.
