The species has not been collected in Illi- nois. The types are from the Kiamichi Mountains of Oklahoma and may indicate an extensive range through the Ozarks, in which case it might eventually be found in Illinois. Palaeagapetus Ulmer Palaeagapetus Ulmer (1912, p. 35). Geno- type, monobasic: Palaeagapetus rotundatus Ulmer (described from Baltic amber). No representative of this genus has yet been taken in Illinois. The only species known from the eastern states, celsus, has been collected in North Carolina and Ten- nessee and is easily recognized in the male by the curious genitalia, fig. 135. Larva unknown. The genus may belong to the Rhyacophilinae. GLOSSOSOMATINAE This subfamily embraces several genera, three of which have been found in Illinois. The larvae make a saddle case formed of a dome-shaped upper portion with a flat strap across the underside, figs. 136, 137; the larva moves along with the anal portion protruding on one side of the strap and the front end protruding from the other. Be- fore pupation the bottom strap is cut away and the dome-shaped upper portion is ce- mented to a rock or other support. The adults resemble Rhyacophila in shape and.
