The male of this species was described by Betten & Mosely (1940, p. 108) as the male of their new species simulans (the female type of simulans is ocellifera). In Illinois we have only three scattered collections for this species, all of them along fairly large rivers, including the Kankakee, Rock and Kaskaskia. Our few records ex- tend from May until late September. The range of the species is poorly known but apparently is extensive through much of the Northeast; records include Georgia, Illinois, Michigan, New Jersey and New York.

This species has not yet been taken in the state but may be found with subsequent col- lecting. We have records from Massachu- setts, Michigan and New Jersey. Phryganea Linnaeus Phryganea Linnaeus (1758, p. 547). Geno- type, by subsequent designation of Westwood (1840, p. 49): Phryganea grandis Linnaeus. The adults of this genus are all large, with a conspicuous pattern of brown and gray, most noticeable in repose, fig. 602. The female ninth sternite, fig. 605, and the short, biscuit-shaped claspers of the male, fig. 603, are diagnostic for the genus. Only three species are recognized in North America, and two of these have been taken in Illinois. Larvae of these two spe- cies have been reared, but no characters have yet been found to distinguish them. KEY TO SPECIES 1. Hind wings with basal two-thirds smoky, apical third dark brown or blackish gray sayi, p. 176 Hind wings uniformly gray or brown- ish, marked at apex only with a few slightly darker darts along the veins
