diameter, and destitute of branches below the cavity, so that I found it 
impossible to climb up. On March 17th I obtained a pair of climbing 
irons, and with these readily ascended to the nest, which I found to con- 
tain the usual number of three eggs, slightly incubated. 
The tree is not one which would be likely to attract attention, as it 
is a vigorous living red oak (not asweet gum as originally stated), and 
the cavity is not conspicuous. The female bird was readily alarmed— 
a slight tap on the tree being sufficient to cause her to leave the nest 
and to retire to some distance. I did not see the male bird at any 
time. 
In this patch of woods gray squirrels are yet comparatively abundant 
and one or more pairs of red shouldered hawks nest there every year, 
besides many crows, but it is doubtful if they can remain undisturbed 
much longer, as the timber is large and valuable and in several sections 
the finest trees have been thinned out quite recently. 
Mr. Wm. T. Davis exhibited a living pupa and mud cone of the 
seventeen year locust, with the following memorandum : 
The pupæ of the seventeen year Cicada have made their appearance. 
While searching for Bryazis, with Messrs. Leng and Granger, on 
April 8th, I found several under boards on the edge of the meadow at 
Old Place creek, one of which I am able to exhibit alive. The ground 
being damp the pupæ had erected their usual towers of earth, the boards 
not lying sufficiently close to the uneven ground to prevent their con- 
struction. 
In the Proceedings for February 10th, 1894, the Cicadas that 
appeared in 1881 should have been referred to Brood XVII instead of 
XVIII.
