28 CONTRIBUTIONS TO CANADIAN PAL^EONTOLOCY. 



Looking at the assemblage of ft)i-iiis as a whole and noting the distri- 

 bution of the species to which they seem to be most neai'ly related, they 

 are yjlainly indigenous to the soil, but would perhaps be thought to have 

 come from a somewhat more northern locality than that in which they 

 were found ; not one of them can be referred to existing species, but the 

 nearest allies of not a few of them are to be sought in the Lake Superior 

 and Hudson Bay region, while the larger part are inhabitants of Canada 

 and the northern United States, or the general district in which the 

 deposit occurs. In no single instance have any special affinities been found 

 with any characteristically southern form, though several are most nearly 

 allied to species found there as well as in the north. A few seem to be 

 most nearly related to Pacific forms, such as the Elaphrus and one each of 

 the species of Platynus and Pterostichus. On the whole, the fauna has a 

 boreal aspect, though by no means so decidedly boreal as one would anti- 

 cipate under the circumstances. 



The other locality for Pleistocene insects is Green's Creek, where in 

 nodules otherwise containing mainly marine organisms still living, three 

 species of land beetles have been found, each belonging to a distinct 

 family, and one of them, Byrrhidje, a family not otherwise represented 

 among Canadian fossils. 



The eight families represented in the older tertiaries of British Colum- 

 bia, are with two exceptions (Scarabasida^ and Nitidulida?, each with a 

 single species) also found in the later tertiaries to the eastward. Of these, 

 half a dozen species have been found in each of the two basins where they 

 are most common, namely, on the Nicola River and the north fork of the 

 Similkameen, the deposits at Nine-Mile Creek having been laid down, 

 according to Dr. Dawson, in the same lake with the latter ; in each case 

 these half dozen species belong to four families, but only one of these 

 families, the Elateridte, is represented in both. All this indicates that 

 what we have found is the merest fragment of a veiy diversified fauna. 

 Yet it remains to be added that Quesnel, perhaps the most prolific loca- 

 lity of all these, has produced but a single beetle, of a family, Nitidulidfe, 

 not elsewhere represented.
