The first list of Lepidoptera for the Douglas Lake region (Welch 1915) included 12 species in the group of five families for which 55 species are now reported. This 358% increase ronly in part the result of enlarging the' 'region" to include all of the two counties which share the northern tip of the Lower Peninsula of Michigan) compares with an increase of 356'4:- in the families Sphingidae-Ctenuchidae (Voss 1970) and 623% in the Noctuidae (Voss 1981). Only the Geometridae remain to complete recording the consider- able expansion of our knowledge of the local macro1epidopteran fauna over the past 70 years.
