. Bulletin. Natural history; Natural history. 308 Illinois Natural History Subvey Bulletin Vol. 31, Art. 7 hidden, giving the paramere the ap- pearance of having a single, broad, bulbous apex. Female genital plate (Fig. 161) small, broad, mm in length. Distal plate broad, deeply emar- ginate apically, forming two broad lat- eral lobes. Basal plate absent. Sperma- thecal apodeme short, not reaching api- cal emargination of distal plate. P. braueri is very closely related to P. speciosa, and little difference exists in the characters of the male terminalia. These species may be separated by the broad, continuous basal band in the wing of P. braueri. In females of P. braueri the genital plate is much shorter than that of P. speciosa. Byers (1954) reported collecting Missouri specimens of P. braueri on small patches of Impatiens in a shaded swale. P. braueri seems restricted to north- western Arkansas and southern Mis- souri (Fig. 184).. spots. Two marginal spots and large first basal spot present. Second basal spot absent. Legs pale yellow. Abdomen dark yellowish brown. Male terminalia dark yellowish brown. Ninth tergum elongate, deeply emar- ginate apically, forming two narrow lateral lobes. Hypovalves (Fig. 136) broad, extending almost to bases of dis- tistyles. Basistyles broad. Dististyles each with small patch of elongate setae near base. Ventral parameres (Fig. 137) narrow, elongate, each with two thin, barbed, branches extending be- yond base of dististyle, united basally to form Y-shaped projection. Female genital plate (Fig. 162) broad, mm in length. Distal plate broad, deeply emarginate apically to form two broad lateral lobes. Basal plate absent. Sper- mathecal apodeme elongate, not reach- ing apical emargination of distal plate. P. bifida is related to P. anomala, but it is easily distinguished from P. anom- ala by the narrow elongate branches of the ventral parameres. Nothing has been reported on the habitat of this species. P. bifida is known on
