Carolana ascriptella (Busck) Can. Ent., 40: 194, 1908.
Sierra Diablo, 6000 ft., 29 May 1973, 2 S $. These two specimens are a state record for ascriptella but more importantly represent a western extension into the mountains. Earlier (Hodges, 1974) ascriptella had been recorded from New Hampshire and Washington, D.C. to northwest Arkansas.
Acknowledgments
I express thanks to the following: the personnel of Big Bend National Park, Guadalupe National Park, and the Texas Park and Wildlife Department, particularly of the Sierra Diablo Wildlife Management Area; Mr. Blanchard, who showed me many excellent collecting sites and allowed me to sort through his light trap catches for small moths; the Photographic Services Unit of the Smithsonian Institution, that made the photographs of the moths; and my wife, Elaine R. Hodges, who made the line drawings.

TWO NEW IOWA RECORDS
During field work for a larger project on the butterflies of Iowa, two species were collected whose occurrence in the state has not heretofore been reported. Population samples repeated over two and three year intervals indicate established residency in contrast to casuals and temporary resident status.
Glaucopsyche lygdamus couperi Grote was first taken on Hayden Prairie, Howard Co., Iowa, 28 May 1972 in considerable numbers. Populations were subsequently noted and samples collected in western Iowa on Cayler Prairie, Dickinson Co., 6 June 1973 and 5-12 June 1974. The species was also found at Fort Defiance State Park, Emmet Co., 6 June 1973.
Breeding populations of Coenonympha inornata henjamini McD. were located in Gitchie Manitou State Park, Lyon Co., Iowa, 12-13 June 1973 and again on 12 June 1974. All of the Iowa localities above are in the northern tier of counties.
Both of these species have been reported in restricted localities in more northern states including South Dakota, Minnesota and Wisconsin. In addition, lygdamus occurs in Illinois, Missouri, Kansas and Nebraska, so that Iowa records are not unexpected. It is assumed that the association of both species with prairie remnants in the Iowa localities mentioned, helps account for the paucity of records. Native prairie refugia have dwindled to less than 600 widely scattered acres within the state; the Hayden and Cayler Prairie sites represent two of the three largest remaining tracts. In my opinion the two butterfly species have been overlooked by collectors rather than the sites recently colonized by the insect.
