Hcspewcapsus demensus (Van Duzee) Fig. 132 Orthotylus demensus Van Duzee, 1925:398. Pseudopsallus demensus Knight, 1930:8. This species was described from Prescott, Arizona, and I have since recognized it from Larimer County, Colorado. Structures of the genital segment are distinctive, having two ter- gal processes, the one on the right side bifurcate on apical half (Fig. 132). Hesperocapsus abroniae (Knight) Fig. 137 Pseudopsallus abroniae Knight, 1930:5. A pale dusky species; three tergal processes relates this species to arlemisicola Kngt. in struc- ture, but size smaller and color different (Fig. 137). This species was described from Fort Lupton, Colorado, where it was breeding on Abroniae elliptica. It was recorded from Phoenix, Arizona; and now 6cj" April 17, 1937, Yuma County, Arizona (L. L.
