appeared. One of the interestiug features was the abnormally early 

 appearance of tbe 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 Gtli of May, far in advance of anything 

 else reported from any other part of the State. In Cunvberland County 

 they made their api)earance 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, twb 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. Bischofif 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 1 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 Railroad 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 j 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 

 ahmg the line of the Atlantic City road. At Atco, and a little north 

 and south of that point on the Camden and Amboy Railroad, and 

 near Clementon, oix 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 Hkrbor 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
