Fore wing length mm. Membranes (Fig. 89) pale yellow, crossveins faintly margined. Apical band dark brown to black, broad, usu- ally entire. Pterostigmal band dark brown, broad anteriorly, broken pos- teriorly. Basal band broken, forming two dark brown spots. Two marginal spots and iirst basal spot small. Sec- ond basal spot absent. In most speci- mens the apical band of the fore wing is broad and entire although several specimens showed the apical band broken into several small dark brown spots and a narrow subapical band. In some specimens a second basal spot was present and the second marginal spot absent. Legs dark yellow. Abdomen dark yellow to dark red- dish brown. Male terminalia dark red- ish brown, oval. Ninth tergum, as in Fig. 117, emarginate apically, forming two broad lateral lobes. Hypovalves (Fig. 140) broad apically, ending well before bases of distisyles. Basistyles broad. Dististyles shorter than ba- sistyles. Ventral parameres (Fig. 141) elongate, barbed, with one branch ex- tending posteriorly beyond bases of dististyles and a mesal branch curved dorsally. Female genital plate (Fig. 163) oval, mm in length. Distal plate short, deeply emarginate apically, forming two acute lateral lobes. Basal plate absent. Spermathecal apodeme elongate, bifurcate basally, not reach- ing apical emargination of distal plate. The shape of the male terminalia of P. anomala resemble somewhat those of P. elaborata but differ markedly in the short hypovalves and heavily barbed ventral parameres. In Ilhnois P. anomala was initially collected along the bottomlands of the Illinois River at Morris in a dense growth of stinging wood nettle. Indi- viduals in southern Illinois were col- lected on jewelweed in shaded areas along small creeks. P. anomala is a western specie
