NOLES ON THE SELF-PRUNING OF TREES: 
JOHN H. SCHAFFNER AND FRED. J. TYLER. 
This paper was published in The Ohio Naturalist, Vol. 
I, pp. 29-32, 1901. The authors give a considerable list of 
woody plants which cut off their own branches by a special 
process. Among them were: Populus alba, Quercus 
acuminata, Prunus, serotina, Salix nigra, and Ampelopsis 
cordata. 
SOME, DISTRIBUTION NOTES: 
EF. M. WEBSTER. 
3y distribution is meant insect distribution, of course, 
and more especially such as have, or are sure to come within 
the boundaries of the state within a comparatively short 
time. 
The 12-spotted asparagus beetle, Crioceris 12—punctata 
has overtaken C. asparagi, in Ontario, Canada, in the west- 
ward.march of these species, and we may now confidently 
look for the former at any time in northeastern Ohio. The 
imported elm leaf beetle, Galerucella xanthomelaena has 
been reported from eastern Kentucky, and, therefore, may 
be expected to appear in the southeastern part of the state 
in the not distant future. 
One of the dung beetles, Aphodius fossor, was intro- 
duced from Europe into Canada many years ago, and spread 
southward through New England and to the westward. 
I have known of its occurrence in northern Ohio for some 
time, as we have a single specimen from about Wooster. 
Quite recently Captain W. M. Hill has sent it to me from 
East Liverpool. The Mediterranean flour moth, Ephestia 
kuhniella, has been reported from Stark county, which 
is not to be discredited as we have reared it at Wooster from 
a culinary preparation known as Grano. The Harlequin 
cabbage bug, Murgantia histrionica, which at one time ex— 
tended northward nearly to Lake Erie, was killed back,
