appeared. Oue of the interesting features was the abnormally early 
appearance of the insects in certain localities. In one spot, a short 
distance south of New Brunswick, specimens were collected which 
reached my hands on the ">th or 6th of May, far in advance of anything 
else reported from any other part of the State. In Cumberland County 
they made their appearance about the middle of the month, and here 
first the Philadelphia papers got hold of the matter from the fact that 
a physician of that locality driving through a burned district discov- 
ered acres of the woods covered by the "chimneys" that these insects 
sometimes build. According to his description, every square foot of 
sod showed dozens of these chimneys, and in each was to be found a 
Cicada pupa. He sent me, at my request, two sods showing the aver- 
age number of exit holes, and sent me also the chimneys taken from 
them. None of the ground covered by me, where the insects were 
appearing, showed any trace of these peculiar chimneys and nowhere 
else in the State were they recorded, except at one point in the vicinity 
of Newark, where Mr. E. Bischoff reports finding them near an old stone 
quarry. A considerable proportion of the State has therefore been 
covered by the insects during the present year, and I have marked on 
a map of the State all the points from which I have been able to receive 
authentic reports of the presence of the insects, but even in the terri 
tory covered there were many points in which the insects did not 
appear. In riding along the line of the Cape May Kailroad from Cam- 
den the insects were noticed for the first time a short distance north of 
Vineland; nothing more was seen of them until Millville was reached, 
and a little north of that point the insects were again seen. Then 
came a considerable stretch of territory where there was no appearance 
of the presence of these insects, until some ten miles north of Wood- 
bine they again made their appearance, sometimes on one side of the 
railroad and sometimes on the other ; sometimes skipping a mile, then 
appearing over a territory as far as the eye could reach, causing the 
oak shrubbery that covers the ground to appear as if a fire had passed 
over the tops. Woodbine seems to have been the center for this aggre- 
gation, and from there to Cape May Court-House, near the middle of 
the Cape May Peninsula, they were noticed in gradually decreasing 
abundance in all the high wood lots. It was the same way in riding 
along the line of the Atlantic City road. At Atco, and a little north 
and south of that point on the Camden and Amboy Eailroad, and 
near Clementon, on the Reading road, the insects were noticed on both 
sides of the railroad in the woods. Towards Hammonton nothing was 
seen of them and very little was noticed until within a short distance 
of Egg Harbor City. Then a colony made its appearance on both sides 
of the railroad, and they were visible for a short distance southeast of 
Egg Harbor City, but petered out long before the low lands near the 
shore were reached. Seventeen years ago the insects, it was said, were 
abundant within the limits of the city of New Brunswick. This year
