vegetation, an interpretation similar to that made from another 
18,000 year old coleopterous assemblage from Port Moody in 
southern British Columbia (Miller, Morgan and Hicock, 1982). 
In the central eastern section of the continent three sites post- 
dating the retreat of Laurentide ice have produced cicindelid 
remains. The Norwood site in Minnesota (Ashworth et al., 1981) is a 
late-glacial kettle which has a sequence of silts overlain by peat 
dated at 12,400±60 yr. B.P. (QL-1083). A left elytron of Cicindela 
cf. C. sexguttata Fabricius was recovered from the upper silt, an 
horizon characterized by a number of open ground beetle species. In 
the Canadian province of Ontario two sites at Kitchener and 
Brampton contain specifically identified cicindelids. The sites are 
approximately equivalent in age to the Norwood locality (ca. 12,400 
to 12,000 yr. B.P.) and both slightly post-date the last major (Port 
Huron) ice readvance in the region. The Gage Street site. Kitchener,
