experimental sample for a 14 C mass spectrometer run at Chalk River 
Nuclear Laboratory, Ontario, Canada. The resultant age of ca 8,000 
yr B.P. suggests that the samples are probably of Holocene age, 
(Miller and Peck 1979, Morgan and Morgan 1980a) or of very late 
Pleistocene age as stated by Pierce (1947b). 
Three Cicindela specimens are known from Rancho La Brea; two 
thoraces of C. haemorrhagica (RLP 8779E and RLP 9014E) and a 
metasternum of C. oregona LeConte (RLP 9465E). RLP 8779E and 
9465E are from Pierce’s “Bliss 29” material, which was collected in 
1929 by W. Bliss from the sites of pits A, B, and C. The samples are 
probably late Pleistocene in age, but this is questionable due to 
unknown locality and possible contamination (Miller and Peck, 
1979). RLP 9014E is from Pierce’s “Pit X”, which refers to mixed 
material, lacking data, and of questionable age. 
The Quaternary presence of C. haemorrhagica and C. oregona in 
southern California is not unexpected. Both are presently widely 
distributed in fresh and marine littoral habitats in western North 
America. Although these two species are not narrowly restricted to 
specific microhabitats, they are always found near permanent sour- 
ces of water. 
New Records of Fossil Cicindelids Elsewhere 
in North America 
Beside the above mentioned localities, a rekindled interest in the 
examination of coleopterous faunas has recently revealed fragments 
of cicindelids in a number of sites in the United States and Canada 
(Fig. 1). All but one of these records are more recent than the last 
review of North American fossil insects (Morgan and Morgan 
1980b). The oldest specimen which is stratigraphically interpreted as 
pre last interglacial (pre-Sangamon) is a partial elytral fragment 
which is probably of the genus Omus from the Mountain View 
-Dump site near Palo Alto, California (D. Adam pers. comm. 1978, 
Morgan unpublished). In the Pacific northwest, a recently examined 
site (Nelson and Coope, 1982) from Discovery Park, Fort Lawton, 
Seattle, has produced the remains of Cicindela oregona LeConte. A 
large and varied assemblage accompanies this find which is from 
sediments previously radiocarbon dated at between 23,000 and 
18,000 yr. B.P. The site pre-dates the last major (Vashon) ice 
advance in the area and suggests a cooler climate with more open
