Description. Length 5.5-7.0 mm (head excluded). Body pubescent;
pubescence patterned as follows: setae on frons and rostrum either all
light brown or white with few light brown setae at middle at upper level
of eyes; setae on pronotum and elytra light brown, dark brown, and
white, intermixed in various combinations, usually with spots as
follows: pronotal disc with 2 dark brown spots on lateral-basal portion
and 1 light brown patch basally; elytral disc with 1 large white patch on
anterior portion; elytral interstriae with numerous dark brown, white,
and light brown patches. Frons convex, with prominent, weakly
elevated median carina extending from epistomal margin to level of
middle of eyes; surface of frons obscured by pubescence. Pronotum
about I.I-L? times wider than long, widest at base; sides converging to
narrowly rounded anterior margin; base broadly emarginate; basal
carina acute; lateral carina acute, joining basal carina at about 80"
angle; disc convex, with medial and basal impressions; basal impression
deep; median impression broad, weak, longitudinal; surface strongly
punctured, reticulate between punctures, usually obscured by
abundant vestiture. Elytra L6-1.7 times longer than wide; apex broadly
rounded; disc weakly impressed along suture, more distinctly impressed

Comments. This is one of the largest species (in body size) of
Anthribidae occurring in Canada. Adults may be easily recognized by
the color pattern ofthe setae, by the characters as given above, and by
the large size. Although the species is common throughout its range,
