The Great Basin Naturalist ^""^^^ UNIVERSITY. Published at Provo, Utah by Brigham Young University Volume XXV July 8, 1965 Nos. 1-2 A NEW NET-WINGED MIDGE FROM IDAHO (BLEPHAROCERIDAE, DIPTERA) Charles P. Alexander* An interesting undescribed species of net-winged midge belonging to the genus Bibiocephala Osten Sacken was taken in Idaho by my friend Mr. James Baker, of Baker, Oregon. I am very deeply indebted to the collector for many new and rare crane-flies taken during the past twenty-five years in several of the western states and provinces. The unique type is preserved in my personal collection. General Account of Bibiocephala The genus Bibiocephala Osten Sacken (see Bibliography) now includes five nominal species, one occurring in Japan, the remaining four names pertaining to western Nearctic species. In attempting to clear the identities and synonymy of the Ajnerican species I am reviewing briefly the series of circumstances under which the vari-ous names were proposed, the papers cited being included in the appended bibliography. Attention may be directed to two recent papers by the writer (1958, 1963) which include more detailed references to the family. Osten Sacken (1874:564-566, figure, venation) proposed the genus Bibiocephala, based on the new species, grandis, taken at high altitudes in the mountains of Colorado, 8,000 to 10,000 feet, August 1873, represented by a single male specimen taken by Lieutenant W. L. Carpenter. Garrett (1922:91) described Bibiocephala kelloggi from a single female specimen taken in the city of Cranbrook, British Columbia, July 13, 1921, b}^ Cecil B. D. Garrett. In defining the species Garrett recorded it as being a male but actually this type is a female. The specimen is in my personal collection having been acquired by purchase from Garrett. It still is uncertain whether this fly is distinct from grandis. Curran (1923) described Bibiocephala grisea, as type of a supposed new genus Bibionus, based on a single male taken at Nordegg, Alberta, June 26, 1921, by James Mc Dun-nough. This evidently is identical with kelloggi which is the prior name. 1. Amherst, Massachusetts.
