OTHER TERTIARY INSECT LOCALITIES. 41 



by two species of Donacia. Finally, a species of Scolytidte must have made 

 certain borings under the bark of juniper. 



Most of these are described and figured in the present volume. Looking 

 at them as a whole and noting the distribution of the species to which they 

 seem to be most nearly I'elated, they are plainly indigenous to the soil, but 

 would perhaps be thought to have come from a somewhat more northern 

 locality than that in whicli 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. Li no single instance were any special 

 affinities found with any characteristically simtliern forms, 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 Pterostichu.s. On the whole, the fauna has 

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

 anticipate under the circumstances. 



Port Kennedy, PenmijJvtnud. — The only locality remaining to be noticed 

 is Port Kennedy, in southeastern Pennsylvania, where the clays in the bone 

 caves have furnished about a dozen species of Coleoptera, described bv Dr. 

 G. H. Horn, in 1870, but now first figured. His descriptions are reprinted 

 in the present Avork, with the results of my own study of the same material.
