This publication summarizes the results of several years study of the beetles of the family Bostrichidae and treats all the species of the family known to occur in America north of Mexico and including Lower California. In addition, a number of exotic species, intercepted from time to time in imports from foreign countries, are included in anticipation of the necessity of correctly identifying such material.

Antennal club with the segments narrowly oblong, second and third segments petiolate at bases, the third distinctly longer than second, and narrowly rounded at apex. Pronotum much wider than long, widest along basal half, with a narrow, transverse groove along base, a triangular, median flattened space along anterior margin, and a narrow, longitudinal, median groove on basal half; sides parallel on basal half, arcuately converging anteriorly, with a number of small tubercles near margins; posterior angles rectangular, each with four teeth; disk with four rather acute, erect tubercles, placed in a transverse row near middle, and a few smaller tubercles scattered over apical half, surface finely densely granulose, the granules distinctly separated, densely, uniformly clothed with short, erect, arcuate, whitish hairs.
