users of this work will be cautious when applying names to species in this genus. Genus Auletobius Desbrochers Auletobius Desbrochers, 1869:396; Voss 1922:27, 29; Voss 1933:110, 113; Hamilton 1969:356; O'Brien and Wibmer 1982:13. Metopon Waterhouse, 1842:8. This genus contains 16 species in North America, mostly in the southern United States, Mexico, or Central America. Three species occur in the southern regions of Canada, one in the west, and two in the east. The distinctive characteristic of this genus is the randomly punctured elytra (except in A. cassandrae).In addition, the rostrum is very slender, the pygidium is covered by the elytra, and the scutellar striae are not evident. Description. Body stout, pear-shaped. Pubescence consisting of short, hair-like, inconspicuous setae. Head conical, widest across eyes; surface punctured. Rostrum slendeq weakly curved; apex weakly expanded. Eyes strongly convex, protuberant. Antennae (Figs. 157, 158) inserted in basal quarter of rostrum (Fig. 157) or in middle of rostrum (Fig. 158); terminal 3 segments distinctly larger than other segments. Pronotum narrower than elytra; disc shining, punctured. Elytra inflated on posterior half, broadly rounded at apex; surface not striated; punctures randomly scattered (except A. cq,ssqndrae); interpuncture space shiny. Abdomen not sexually modified. Pygidium concealed by elytra. T5pe species. Inuoluulus sanguisorbae Schrank, by subsequent designation. Comments. Hamilton (1969) gives a key to the species occurring in the United States, as well as descriptions, distributions, and other essential information. Key to species of Auletobius in Canada 1.
