1893.] Proceedings of Scientific Societies. 1113 
rows by Mr. Hollick, gave an account of the southward migration of 
the species along the Atlantic Coast, noting its occurrence on Long 
Island, ete. This is the first record of its being found alive on our 
Island. 
Mr. Leng recently collected in Augur Lake, near Keeseville, N. Y., 
a rare Dytiscus beetle, probably D. harrisii, which he brought home 
alive in a tin can as his alcohol bottle was not sufficiently large. 
Upon opening the can for the inspection of the insect, we were pleased 
to find a dark brown Gordius worm of unusual size. After carefuily 
untwisting and unkotting the tangled creature, which took our united 
efforts, we measured it with a rule, and discovered that it was twenty- 
eight inches long. In Dr. Packard's miology it is stated that hair- 
worms “ live in ground-beetles and locusts,” twisting around the intes- 
tines of their hosts. 
The severe storms of the 24th and 29th of August blew many green 
hickory nuts from the trees, and in spite of their unripe condition the 
shell-bark nuts were promptly devoured by gray squirrels. Under one 
of the trees on Richmond Hill, there were many quarts of the outer 
green husks gnawed fine, and of the nuts from which the kernel had 
been extracted after the outer bitter covering had been wholly or in 
part removed. It appears from this that it is probably the firmness of 
their attachment to the end of the tree branches, and not their green 
husks, that prevent the unripe hickory nuts from often being eaten by 
squirrels. 
This morning a green example of the walking- sinit insect ( Diaphero- 
mera femorata) was found in the Clove Lake swamp on a golden rod. 
Though common northward, in the Hudson River valley, it is rare with 
us, and this is only the fifth recorded specimen from our Island. 
Mr. Davis also exhibited some exotic water plants that had been 
introduced by some person of an experimental turn into one of the 
numerous small ponds in the woods north of the Moravian Cemetery. 
Among them was the Chillian Mermaid-weed, the South American 
Pond weed (Kichornia crassipes), a lily and one of the sedges, all of 
which seem to do well among the native plants.
