Illinois Records.—Golconda: April 17, 1930, Prison & Ross, 2$, 1$. Herod: May 10. 1935, C. O. Mohr, 1 ? . Phylocentropus lucidus (Hagen) Polycentropus lucidus Hagen (1861, p. 294); This species has not yet been taken in Illinois. It is known from New York, Nova Scotia, Pennsylvania and Tennessee. In the front wing Rg does not join M, and on this basis the species was referred to a new genus, Acrocentropus, by Betten. The struc- tures of the male and female genitalia, how- ever, indicate clearly that it belongs with placidus. The female is similar to the male in color and in general structure; the genitalia, fig. 220, have the eighth sternite heavily sclerotized, the apex broad, slightly indented on the meson, resulting in very wide lobes; bursa copulatrix long, semi- membranous, and attached to sclerotized rods of the ninth segment. Allotype, female.—Bear Brook near Blue Mountain Lake, New York: June 19, 1941, Prison & Ross. Neureclipsis McLachlan Neureclipsis McLachlan (1864, p. 30). Geno- type, monobasic: Phryganea bimaculata Lin- naeus. Of the three species known from North America, two have been taken from Illinois, and the third occurs to the northeast. We have reared only crepusciilaris; this larva agrees very well with Ulmer's description of bimaculatus, and it is possible that
