Abstract

During the summer of 1954 studies were initiated on the Heleidae of the Douglas Lake region of Cheboygan County, Michigan. Two male specimens, representing two previously undescribed species, of the biting midges of the genus Alluaudomyia were taken in recovery cages. The genitalia were so markedly different from any of those discussed by Wirth (1952) in his paper on this genus in North America, and from any species mentioned by Goetghebuer (1933), Kieffer (1925a, b), de Meillon (1939) de Meillon and Hardy (1953), Okada (1942), Tokunaga (1940a, b) and Vaillant (1954), that describing these species from single male specimens was felt to be justified. Although male wings are not as a rule described it seemed advisable in include illustrations and descriptions of these wings since no females were recovered and since the aedeagus of one was somewhat distorted due to folding. The terminology of wing venation follows that of Tillyard's modification of the Comstock-Needham system, a system which has been used by various students of this family in recent years, thus Cu1 and Cu2 of some workers become M3+4 and Cu1 respectively, and cell Cu1 becomes cell M4. Much of the study was done with 18x eyepieces and a 43X objective.
