A PINE SAW-FLY FROM ARKANSAS. 
I send you specimens of the pine worm of which you have received 
mention. They are fast disappearing, but a great many of the largest 
trees are completely stripped of their foliage, and the sign of their rav- 
ages is visible on every tree and bush. I have never noticed but one 
instance where they had eaten any other tree than the pine, and that 
was a Small ash on which a few had lodged in falling from a tree after 
defoliating it. The leaves of the ashhad been eaten to aslight extent. 
They never touch the new growth, but confine themselves entirely to the 
growth of last year. * * * —[W. A. MOSELEY, Camden, Ark., May 
4, 1883. 
[The pine worm proved to be the undescribed larva of a saw fly of the 
genus Lophyrus. These insects undergo their transformation to pup in 
silken cocoons on the surface of the ground, among the leaves and other 
rubbish; hence burning over the surface of the ground in winter, where 
it is possible, will be a good remedy. Ornamental trees can be preserved 
from their attacks by syringing them with hellebore water or Paris green 
water. | 
SAW-FLY LARVA ON WHEAT HEADS. 
I have as fine a field of wheat as I have seen this season. This morn- 
ing, in looking over it, I find upon the heads quite a number of such 
worms as are here inclosed. They take a portion of the grains out of 
the heads they attack. They are not very numerous, perhaps three or 
four in a rod square. [am at a loss to know what they are, or whether 
they will materially injure our wheat. My neighbors also have them. 
Will you please inspect them?—[J. C. HosTEeTTER, Minerva, Ohio, 
June 16, 1883. 
Your favor of 21st instant is at hand ; also mailing box and stamps. 
I have just returned from a walk around a twenty-acre field of wheat. 
My object was to pick off a dozen or more of those worms to send you. 
To my utter surprise (though making diligent search) I found but three, 
one of which I lost on my way to the house. Only a week ago I could 
have found any number of them in the same field. They are now gone, 
having either dropped off, or been taken by the birds, or both. Please 
pardon me, therefore, for sending only those two discoveries for inspee- 
tion. If I find more I will send again. I think these are full size, or 
nearly. I found them on small heads of wheat, the same inclosed. You 
are evidently clearly right in saying we need not apprehend much dam- 
age from them. Their time is of short duration and seems to be con- 
fined to the period soon after the wheat is in head. I don’t think they 
affect the kernels when fully formed.—[{J.C. HOSTETTER, Minerva, Ohio,
