Body (Fig. 3) elongate oval, distinctly tapered posteriorly; dorsal color dark rufous to almost black; in most specimens, color of pronotum lighter than color of elytra; elytra with 4 yellow-red, subquadrate maculae: anterior pair near humeri and not attaining suture, posterior pair in apical third of elytra, attaining suture in some specimens; antennomeres uniformly rufous in color, antennomere 11 slightly lighter in color than preceding articles; venter uniformly dark rufous; dorsal pubescence relatively short, inconspicuous; eyes (Fig. 10) widely separated (space&gt; 3x length of antennomere 1), inner margin of eye moderately deeply emarginate; antennae (Fig. 19) relatively short, antennomeres 7-11 distinctly widened; antennomere 7 triangular, 8-10 distinctly wider than long; antennal sensilla completely annular (as in Fig. 25); last maxillary palpomere slightly widened, subsecuriform; procoxal process elongate, spatulate distally, extended to past posterior margin of procoxae, bent dorsally at distal end; prothoracic episternal suture absent; elytral punctation fine, not arranged in longitudinal striae; meso- and metatibiae with scattered short spines, oblique ridges absent (Fig. 16). <b>Distribution</b> (Fig. 27) <i>Holostrophus bifasciatus</i> is an eastern species; in Canada, specimens have been collected from west of Lake Superior in northwestern Ontario, east to Nova Scotia and Prince Edward Island. Most Canadian specimens are known from southern Ontario and Quebec. Th e species is very widespread in the eastern half of the United States, almost entirely east of the Mississippi.
