emerging from the wood of a desk that had been in use for 20 
years. One of our commonest species, Chrysobothris femorata 
is, however, said by Packard to complete its transformations in 
twelve months, so the usual period is uncertain. 
This insect is found every year in numbers on oaks and oc- 
casionally other trees. I took the greatest number about 1880, 
when Mr. Davis and I found a log near Silver Lake literally 
alive with them. They would take short flights and lighting 
on the log, hide in the crevices of its bark, which by their col- 
or and deep wrinkled furrows they simulate to a degree. Many 
other species have this restless habit of flying from place to 
place, and on the wing, look and buzz very like flies. 
Two species of Agrihis are also abundant — riificollis and 
otiosiis — the first usually on wild blackberries and the second 
on a variety of young saplings. When the trees around Mart- 
ling's Pond were cut down about three years ago, a growth of 
saplings sprang up on which the species oi Agrilus were quite 
plentiful, and besides many otiosus an occasional bilineatus or 
interruptus was found. 
I have never found any of our other species in great num- 
bers. Of the Anthaxia all my specimens have come from 
a clump of wild cherry in the Clove Valley. Chalcophora is 
said to breed in pine, but a good deal of beating has yielded 
little. The species have been found washed upon the 
beach, and one specimen of liberta was taken by Mr. Davis 
flying at Watchogue. Two species of Brachys occur on the 
leaves of certain oaks, and I have found them in North Caro- 
lina in great numbers. Probably they will be found abundant- 
ly somewhere on Staten Island. 
Chrysobothris aziirea was a notable capture of 1886, and is 
everywhere counted a rare insect, but from May to July of that 
year it was plentiful on a species of dogwood in a thicket now 
burned over and turned into " Prohibition Park." The house, 
built, as I am told, for the dominie, stands just above where the 
first was taken. The beetles were very quick in their movements, 
and vvcre captured by beating the trees over an umbrella, out of 
which they flew again as soon as they touched it. Several 
were observed resting on the main stems of the young trees, 
with the anterior legs extended, and the last ventral segment 
touching the bark, and they were probably females depositing 
their eggs. None have been found since 1886, nor have I been 
able to find the larvae in the few trees that are left.
