. Bulletin. Natural history; Natural history. 302 Illinois Natural History Survey Bulletin Vol. 31, Art. 7 Panorpa hungerfordi is distributed through Wisconsin, Michigan, and Ohio (Fig. 176). Panorpa Helena Byers Panorpa helena Byers (1962b: 474). $ , 9. Type-locality: Swampy woods south of Hopewell Lake, French Creek State Park, Berks County, Pennsylvania. Panorpa venosa (Authors). Synony- mized by Byers (19626). Head dark yellow, thorax reddish brown. Fore wing length mm. Membranes (Fig. 80) clear to amber, crossveins not margined. Apical band dark brown, broad, entire, occasionally having few small clear spots. Ptero- stigmal band dark brown, broad, apical branch generally separated, forming small spot. Basal band broad, entire. Marginal and second basal spots ab- sent. First basal spot small. Legs pale yellow, fourth and fifth tarsal segments dark brown to black. Abdomen dark yellow. Male termi- nalia dark yellow. Ninth tergum, as in Fig. 117, oblong, rounded basally, ta- pered apically, deeply emarginate apex forming two laroad lateral lobes. Hypo- valves (Fig. 120) moderately thick, ex- tending to bases of dististyles. Basi- styles broad, each with one to three dark black setae near bases of disti- styles. Dististyles about two-thirds length of basistyles. Ventral parameres (Fig. 121) narrow, elongate, barbed, unbranched, extending to bases of dis- tistyles. Female genital plate (Fig. 154) oval, mm in length. Distal plate oval, tapered basally, apex emar- ginate. Basal plate absent. Spermathe- cal apodeme elongate, base bifurcate, apex not reaching apical emargination of distal plate. The dark setae at the bases of the dististyles relate P. helena with P. amer- icana, but they differ in the shapes of the hypovalves and the ventral para- meres. If the dark setae at the bases of the dististyles were absent, the male terminalia of P. helena would resemble closely those of P. insolens. P. helena is probably the most abun- dant and widely distributed
