variable populations have been described as separate species, but all merge from one to another. Valentine (1971) regards these populations as subspecies. All specimens in eastern Canada belong to the nominate subspecies; those from the western United States, and possibly southern British Columbia, are T! tomentosus ircegularis Tanner. Adults are readily recognized by the small size, by the very shallow V formed by the basal carina on the pronotum, and by the diffuse color pattern. Nothing is known ofthe life history or habits ofthis species except for the notes given above. 1.4 ,k+r FN 5{i-- \, Map 7. Collection localities of Trigonorhinus tomentosue.

Trigoruorhinus sticticus : Valentine 1957 :9 ; Valentine 1960 : 58, 81 ; Valentine l97L:247. Anthribus uariegatus Say, 1826:251 (name preoccupied) (no type locality given; type destroyed). Brachytarsus obsoletus Fahraeus, 1839:167 (type, Pennsylvania; NHMP). Description. Length 1.8-3.2 mm (head excluded). Integument of head, pronotum, and elytra mottled black and reddish brown. Pubescence tricolored, composed of white, light brown, and very dark brown setae, arranged as follows: pronotum with dark brown setae predominant on basal area and white or light brown setae predominant on anterior portion. Elytra with scattered light brown setae intermixed with white setae; posterior and lateral portions sometimes with scattered spots of dark brown setae surrounded by white setae in irregular pattern; interstriae 1-4 with 1 large or 2 connected dark brown spots on basal portion and 2 dark spots on median portion; median spots sometimes connected by dark setae on interstriaet and2. Frons weakly convex, transversely impressed below eye level; surface finely punctured. Rostrum moderately prolonged; surface as on frons. Pronotum very slightly wider than long, widest just behind middle; sides distinctly arcuate, converging to narrowly rounded anterior margin; disc evenly convex, with narrow transverse impression just before basal carina; surface shining, with obscure, shallow punctures; interpuncture space minutely punctured or reticulate; basal carina weakly arcuate, acutely elevated. Elytra about l-.3 times longer than wide; sides evenly and slightly arcuate to broadly rounded apex; disc evenly convex; striae weakly impressed, with large, obscure, more deeply impressed punctures; interstriae I.0-2.0 times wider than striae, minutely punctured. Distribution. Quebec to British Columbia, and Northwest Territories south through the United States to California and Utah in the west and to Iowa and Florida in the east. British Columbia: 5 km south of Vernon. Manitoba: Boissevain. Northwest Territories: Fort Simpson (not on map). Ontario: Brittania, Chatham, Constance Bay, Delhi, Forestville, Leamington, Madoc, Marmora, Ottawa, Pelee Island, Rondeau Park, Tilbury Toronto, Turkey Point, "Victoria," and Walsingham. Quebec: Covey Hill, Gatineau Park, Hull, Laniel, and Wakefreld. Saskatchewan: Elbow, Greenbush (not on map), Hudson Bay, and Prince Albert. Comments. This is probably the most common species of this genus in Canada. Adults are readily recognized by the color pattern described above. Nothing is known of the life history or habits of the species, except that it breeds in smut fungr, especially on corn, wheat, and wild grasses (Andropogon species). 45
