78 STATEN ISLAND INSTITUTE OF ARTS AND SCIENCES 
The importance of planting trees along the streets and inland 
roads of the island was discussed by all present, and the fact that 
the city authorities had done so little in this respect was lamented. 
The meeting of December 29, 1920, was held at the residence of 
the president, Miss Miriam A. Campbell, 275 Watchogue Road, 
Westerleigh. 
Mr. Lenwood Bacher showed the eggs of Microcentrum rhombi- 
folium (Saus.) collected at Princes Bay. This species of katydid 
lays its eggs along a small twig or the edge of a leaf, one egg 
neatly overlapping the other. 
Mr. Chas. W. Leng showed the flea-beetle Haltica knabi Blatch- 
ley, among material determined from the island lov” Wile, lal (C, Wall 
Mr. Edw. J. Burns exhibited several field mice collected at 
Sands Point, Long Island, which he had collected by encouraging 
a dog to dig them out, and then taking them away before the dog 
had time to swallow them. 
Mr. Wm. T. Davis read extracts from two papers by Arthur 
Jacot, which appeared in The Nautilus for January 1919 and April 
1920. The first is entitled Marine Mollusca about New York City 
and records about 45 species from Staten Island collected at three 
definite stations between Fort Wadsworth and Great Kills. The 
second paper is On the Marine Mollusca of Staten Island, N. Y., 
and deals with species collected in the summer of 1919 at Great 
Kills and vicinity. ‘“‘We found but few species,” is the author’s 
comment. He states that “ Modiolus demissus demissus is found 
very thinly scattered among the individuals of the northern form 
[M. d. plicatulus|. That the southern variety was once the pre- 
dominant form over this area is evident from the fact that the sod 
banks on which plicatulus is now living contain the dead valves of 
the southern form exclusively, in large numbers and buried to a 
depth of 8 or to inches below the surface in company with Mya 
arenaria.” 
All present at the meeting expressed their regret at the cutting 
down of most of the trees in Silver Lake Park and the burning
