found by me was proved to be the same species from Staten Island. 
Col. Pike found in 1889 that it had bored nearly all of the trees, 
mostly maples, from Carlton Avenue to the entrance of the park, and 
that in 1891 it had extended its ravages throughout the city. He also 
mentioned it as having appeared in Astoria, New Rochelle, Jamaica, 
New Lots and Flatbush. 
In August, 1887, Mr. J. B. Engelman took three specimens of the 
Leopard Moth in Newark, N. J., and in 1888 many more were found. 
Previous to this the very rare occurrence of the moths in this country 
had been credited to the importation of wood containing the larve. 
In 1889, Mr. Beutenmuller mentions it as having been found not 
uncommonly in Central Park. From these facts it will be seen that 
this destructive insect from the Old World has become quite generally 
distributed in this vicinity. 
Mr. Davis also read the following note : 
With Messrs Kerr and Leng, on the 26th of last February, I observed 
about twenty-five Snow Buntings—Plectrophenax nivalis (Linn.)—in a 
field on Todt Hill, near the highest point of the island. They were 
feeding in the few places where there was no snow, and flew occasion- 
ally in a remarkably compact flock, from one to another of these 
isolated spots. This bird has not been reported on the island for a 
number of years, and its present occurrence is undoubtedly due to the 
severity of the winter. 
Mr. J. H. Bowles, in “Science,” for January 13th, 1893, comments 
upon the abundance of the Pine Grosbeak—Pinicola enucleator (Linn.) 
—and the scarcity of the Snow Bunting about Ponkapoag, in eastern 
Massachusetts, and gives as a cause the unusually cold weather. The 
Grosbeaks and the Buntings have each ranged further south than for 
several years past. Though the weather has been severe, robins have 
been seen sparingly on the island during every month of the winter. 
Mr. Arthur Hollick remarked that the last time he remembered see- 
ing the Snow Buntings in abundance in this vicinity was during the 
winter of 1872-73, when they appeared in great flocks, accompanied 
by the Horned Lark—Otocoris alpestris (Linn.). That — ay 
were particularly numerous on Fort Hill, New oe many 
days in December and January, and large num killed by 
gunners. . 
Mr. Walter C. Kerr exhibited, under the ‘microscope, sity fon 
Quercus nigra L., Q. ilicifolia Wang., and Q. brittonii Davis, an 
the following paper in connection with them :
