The Stevens Point specimen represents an aberrant morph, when compared to lab-reared or other wild-caught interspecific hybrids of Limenitis. The aberrant pheno-typic characters of this specimen suggest that it might represent a case of natural hybridization between an intergrade of the arthemis-astyanax complex and archippus, or possibly the backcross of a male arthechippus to the arthemis parent (no females of arthechippus are known, presumably due to heterogametic inviability).
Two recent interspecific crosses of female proserpina intergrades with archippus males in the laboratory have produced a 1:1 ratio of arthechippus and rubidus siblings (A. P. Piatt, pers. comm.). However, the above sampling ratios, and possibly the reduction of mahogany ground color in the wild hybrid, suggest that the latter speculation is more probable.
I am greatly indebted to Dr. Austin P. Piatt, University of Maryland Baltimore County, for suggestions, materials, verifications, and review of the manuscript. Thanks are also due to Dr. Charles A. Long, Director of the Museum of Natural History, University of Wisconsin, Stevens Point, and Mr. Peter L. Borgo, University of Delaware, for their consideration and comments. Father Roy Parker, Holy Cross, inked the drawings.

EXTENDED RANGE DISTRIBUTION NOTES ON GEOMETRIDAE
Ten years of collecting moths in the Midwest has resulted in many interesting and unusual captures. Some of these species appear to be far out of their previously recorded ranges and these records may prove to be of interest to the researcher and collector alike. Among the most notable of these are Itame abruptata (Walker) a northern species previously known to occur in Canada and Northeast United States which was taken in Franklin Co., Missouri (5 and 7 June 1972), and in Washington Co., Missouri (6 June 1972) (several fresh specimens of both sexes); Euchlaena irraria (Barnes & McDunnough) another northern species before only known from Canada and as far south as Pennsylvania which was taken twice in Washington Co., Arkansas (27 May 1967 and 1972), and once in Franklin Co., Missouri (6 June 1972) (all fresh males); Glena cribitaria (Guenee) an eastern species with the nearest previous record from its type locality of Northern Illinois was taken several times in Carroll Co., Arkansas (May 1965), Washington Co., Arkansas (April 1967, May 1966-9 and June 1971), Benton Co., Missouri (May 1970), and Washington Co., Missouri (June 1973) (in fresh series of males and females); Lytrosis sinuosa Rindge an eastern species with its nearest previous record from Oktibbeha Co., Mississippi was taken in Washington Co., Arkansas (4 June 1971, 27 May 1972) (fresh males), and Franklin and Washington Co., Missouri (5-7 June 1972) (in fresh series of males and females); Chloroteryx tepperaria (Hulst) a species of the Gulf States was taken in Washington Co., Arkansas (1 September 1968) (a single male), and 21 August 1971 (three fresh males); and Heterophleps refusata (Walker) a northern and eastern species previously taken as far south as Virginia was taken twice in Clay Co., Missouri (29 May 1968, 4 May 1972), and once in DeKalb Co., Missouri (21 June 1972) (all fresh males).
