Natural Science Association of Staten Island.—January 
13.—The Secretary read an invitation to attend the funeral of the 
Rev. Samuel Lockwood, of Freehold, N. J. Also the following 
extract from a communication by Mr. Ira K. Morris, which was 
adopted as the sentiment of the meeting, ordered spread upon the min- 
utes and a copy transmitted to the family of the deceased : 
It is with profound sorrow that we learn of the death of Professor 
Samuel Lockwood, of Freehold, N. J., on Tuesday last. By this sad 
event our Association has lost a very warm friend, and we shall feel 
most keenly the absence of his kindly encouragement and intelligent 
criticism. For years past he has taken a deep interest in all our pro- 
ceedings. 
Mr. Wm. T. Davis exhibited specimens of and read the following 
paper on Staten Island Harvest Flies. 
Dr. Harris, writing of harvest flies, or locusts, in his “ Insects Inju- 
rious to Vegetation,” says of Cicada canicularis Harris: 
“During many years in succession, with only one or two exceptions, 
I have heard this insect on the 25th of July for the first time in the 
season, drumming in the trees, on some part of the day between the 
hours of ten in the morning and two in the afternoon. It is true that 
all do not muster on thesame day; for at first they are few in number, 
and scattered at great distances from each other ; new-comers, however, 
are added from day to day, till in a short time, almost every tree seems 
to have its musician, and the rolling of their drums may be heard in 
every direction. ” 
This Cicada is much less common on Staten Island than in Massa- 
chusetts, where Dr. Harris heard it sing so regularly on the 25th of 
July. It is plentiful, however, up the Hudson River, in northern New 
Jersey and in partsof Pennsylvania. On our Island its place is taken 
in point of numbers, by Cicada tibicen L., (C. pruinosa Say), a larger 
insect with a much more impetuous song. The species first appears 
about the second week of July, and I have recorded its song in the 
past as follows: : 
July 15, 1879, July 17, 1885, July 12, 1887, July 14, 1888, (three 
individuals), July 9, 1889, July 9, 1890, July 11, 1891, July 11, 1892. 
icada tibicen L., also sings after dark on warm nights, but itis a 
lazy, languid song, as if the insect were tired, and it totally lacks the
