hairs stand so close together that the barbs almost touch. Thickly 
studding the leaf were many dead- and dying mosquitoes, specimens 
of aphis, and other small insects. Some of these were caught by 
the head, but most of them were held by the legs or proboscis, as 
their heads were too large to slip between the barbs. All were more 
or less mutilated, probably by other insects. A sweet fluid was 
secreted by the leaf, and this attracted the insects. There was no 
evidence of any digestion going on, as none of the victims could 
get close enough to the surface of the leaf to be touched by the 
fluid. 
A good character lies in the seed of Acer grandidentatum. The 
cavity m which the embryo lies is spherical, and always remains so, 
while the cotyledons are simply folded. In Acer glabrum the seed- 
cavity is compressed and deeply reticulated, so that the seed is 
crumpled. The cotyledons are strongly coiled.

Notes from Chemung County, N. Y.-In May, 1880, I collected 
an Umbellifer, which for some time I could not satisfactorily iden- 
tify. The Rev. J. H. Wibbe, of Oswego, has now identified it for 
me a.% C/KErophy/lum procumbens,l.am. The onlv station known to 
me IS in the town of Ashland, along the Chemung River, and it now 
IS spreading along the south-west bank of the D. L. & W. Railroad 
track. This is its northernmost station, since Prof. Gray gives its 
geographical range as New Jersey, Illinois, and southward
