Genus Dipogon Fox Small sized, stout species, the forewing to 10 mm. long; clypeus broad and short; mandible with 3 teeth, counting the apical point (in all other Nearctic Pepsinae, the mandible has only 2 teeth); cardo of maxilla of female with a fascicle of long hairs curving to and approxi- mately reaching base of mandible (this fascicle is lacking or undevel- oped in all other Psammocharidae); pronotum long, flat, its hind margin arcuate; second intercubital vein curved, oblique; second recurrent vein reaching second cubital cell at its basal to ; cubital vein reaching the wing margin in all species but those of the pulchripennis group; base of first discoidal cell without an irregularity in the wing membrane; nervulus beyond the basal vein by about to its length; nervellus ending some distance before the juncture of cubitella with discoidella; anal lobe about as long as submediella (pi. 1, figs. 9, 10); hind tibia smooth dorsally, the brush on its inner side moderately broad, without a subapical constriction; last segment of tarsi without preapical bristles; tooth on tarsal claws small, erect, and acute. The species of Dipogon probably all nest in holes in wood. The females of the subgenus Deuteragenia are taken most often on stumps and the trunks of dead trees, while those of the subgenus Dipogon are more frequent on smaller twigs and branches.
