from T. audax generally in being larger and less elongate and in having sparser punctation on the frons, larger eyes on the ventral side, usually a more transverse and more convex pronotum, the prosternum slightly convex in front of the intercoxal process, and a setiferous patch on the ventral side of the male fore femur. In addition, the width of the head across the eyes is a little less than in front of the eyes. The most reliable characteristics for the separation of the two species are listed in the key (H, couplet 13). Sexual dimorphism: Males have a setiferous patch on the posterior side of the fore femur. Females have no such patch. Distribution: Occurs throughout northern and eastern Europe and probably established in Egypt and Portugal (Halstead 1969). In North America the species was first recorded in 1977 from specimens collected in Kentucky. It was found for the first time in Canada by Loschiavo in 1979, in Winnipeg in a boxcar, and since then it has been reported in Nova Scotia, New Brunswick, Quebec, and Ontario. Economic importance: In Canada this species has been found, sometimes in large numbers, only in boxcars carrying flour. As noted by Becker (1982), the species is of little importance but could become a major pest of flour. In Europe T. madens has been reported as a secondary pest in flour mills and warehouses; in Czechoslovakia it also causes considerable damage to pollen stores in beehives (Halstead 1969).

TROGOSITIDAE bark-gnawing beetles This family includes about 20 species in Canada. The adults and larvae are found in or under logs, fungi, and the bark of dead trees. Many species prey on wood-eating insects or their eggs; other species feed on fungi or rotten plant materials. Only one species of trogositids occurring in Canada is associated with stored products. Tenebroides mauritanicus (Linnaeus) cadelle Diagnosis: The species is distinguished from the other beetles dealt with here by its general habitus (Fig. 240). Superficially, it resembles some species of tenebrionids but differs readily from them in having the eye not incised by the 191
