species from Burlington, Vermont. Sizes: Bm-lington, 17.5 to 19™"; Con- 

 necticut River, smallest, 19 to 20.5°""; largest, 22 to 27°"". "Barely 1 inch 

 (25.5°"") long, thin walled" (Grray). "Northern boundary, Vermont" 

 (Michaux). I am informed that but a single tree of the species is now 

 found in the county, and this upon the Hatfield Meadow. 



Quercus alba L. — A few well-preserved leaves. 



Quercus coccinea Wang., var. ambigua. — Leaves and abimdant acorns in 

 all stages of growth. " The gi'ay oak appears, by \u\ father's notes, to be 

 found farther north than any other species in America." (Michaux, Sylva, 

 vol. 1, p. 98.) 



"Along the northern borders to Lake Champlain and northward." 

 (Gray, Manual, 1872, p. 434.) 



Fagws ferruginea Ait. — Next to the sycamore, the most abundant plant 

 represented. Leaves of full size, large fragments of tlie wood and bark and 

 nuts alike abundant, the latter very larg-e and surpassing in size those now 

 found in the vicinity. 



"Common, especially northward." (Gray's Manual, p. 455.) 



"Almost exclusively confined to the northeastern United States and to 

 the provinces of Canada." (Michaux, Sylva, vol. 5, p. 22.) 



Betida alha L. — Large branches with bark marked exactly as in the 

 common white birch. 



Besides these many other indeterminate plants were studied — willow 

 leaves, grape vines, grasses, liliacese, lycopodium, lichens, various seeds, and 

 even a flower. 



THE PLEISTOCENE BEETLES OF FORT RIVER, IVIASSACHUSETTS. 



By Samuel H. Scudder. 



The insects found by Prof. B. K. Emerson in the old bed of Fort 

 River in Hadley, Massachusetts, near its entrance into the Connecticut, 

 have no special interest beyond the fact that they are the first insects 

 found in such deposits in New England. They consist wholly of Coleop- 

 tera, and represent five species and four families, viz: Carabidse, Dytiscidse, 

 Elaterida^, and Chrysomelidte, the latter having two species. At least three 

 of the insects, perhaps all, belong to species not now known to exist, but 

 so far as can be told with any certainty, all belong to existing genera, 

 though some doubt may reasonably be claimed for the single species of
