feared. The old remedy consisted in cutting out the larve, and this should still be 
practiced in the case of any that escape the treatment indicated above. The larve 
are of slow growth, and are found in the vines up to the end of September or even 
into October. When fully mature they leave the vines and burrow into the soil, 
changing to pupz, and pass the winter in this stage, transforming to moths the fol- 
lowing spring.—[September 4, 1891. 
Forest Injury of the Oak Edema. 
The Oak Edema, FL. albifrons, is very bad in Michigan. Whole forests of Oak, 
Elm, and Maple are being entirely stripped of foliage. Of course, it is not likely 
that such serious devastation will occur next year, and the defoliation so late is not 
so serious as when it occurs earlier, yet such extensive raids are worthy of record, 
so I send it for INSEcT LirE.—[A. J. Cook, Michigan, September 12, 1891. 
On the Treatment of Tent Caterpillars. 
I would like to know if you can give me any light on the subject of getting rid of 
the Tent Caterpillar; they are ruining my business in this State, as bee-keepers are 
getting but little, and in many places, no honey, hence you see they do not want 
supplies. This year I have not obtained a pound of honey from 123 colonies from 
Basswood, and as we expect nine-tenths of our honey from that source we will either 
have to quit the business or get rid of the worms in some way. After they stripped 
the Basswood trees last summer they then went on the Oak and Elm until our heavy 
forests in these parts looked as naked as winter. I wrote to the Department of 
Agriculture three or four years ago about the matter and was told that there was little 
danger of their appearing in the same districts more than one or two years, but they 
have been increasing ever since. I have read a few articles concerning the experi- 
ments for killing Chinch Bugs by spreading a disease among them with infested bugs. 
and wondered if something could not be done in the same line with the Tent Cater- 
pillar.—[F. C. Erkel, Minnesota, October 3, 1891. 
RepLy.—There is nothing to be hoped for in the way of contagious disease which 
can be artificially controlled, and if the Tent Caterpillars are growing worse in your 
neighborhood your only release will be by the most energetic measures. It is an 
open question whether it will pay you to go through the woods in your neigh- 
borhood and destroy the webs wherever they are seen, either by spraying a Paris 
green or London purple solution into them, or by burning them off with torches, 
but no other remedy can be suggested. It should be done early in the season, as 
soon as the webs appear, and before the Basswood begins to bloom.—[October 8,

The Catalpa Sphinx. 
I have a splendid Catalpa tree which has been so infested with a large, rapacious 
worm, that I had made up my mind to have it cut down, when I thought perhaps 
you could suggest some remedy for this pest. When the leaves were fully grown, 
and the bloom putting out in June, a great number of worms appeared on the leaves, 
about half grown when noticed, and eating ravenously. Ina few days they were 
fully grown, and in a few more days every leaf was eaten up, and those that had 
not been shaken off the tree fell off, or crawled down and disappeared. 
The tree put out fresh leaves, and when they were half grown I looked closely and. 
found myriads of the young inch-long worms hard at work, eating away for life. 
This last crop did not make so long a stay, seeming to be full grown in a few days, 
and left before the leaves all disappeared. When grown it is three inches long, a 
bright green color underneath, with a black stripe down the back and a white stripe 
on either side of the black one. It is the handsomest worm I know, with no horns 
or repulsive looking stings about it. What can I do to save the tree? It is twelve 
_ years old, and I never noticed any worms on it till four years ago, when we shook 
them down and killed them.—[Mrs. R. E. Peyton, Virginia, September 30, 1891.
