Ohio, survived the winter, but the beetles disappeared early in the 
summer and none have been found since that time. The codling moth 
(Carpocapsa pomonella Linn.) has not been as destructive this year 
as usual, the spring cankerworm (Paleacrita vernata Peck) seems to 
be on the increase In many sections, and the tent caterpillar (J/ala- 
cosoma americana Fab.) was abundant and injurious in the north- 
western part of the State. 
Early in May a report was received from Mr. E. E. Richards, who 
is the owner of a large orchard in Adams County, southern Ohio, that 
his peach trees were being defoliated by insects. An investigation 
made by my assistant, Mr. Swezey, on May 15, showed that the bucls 
and young leaves in one part of the 3-year-old peach orchard 
were being seriously injured by the red-legged flea-beetle (Cvrepz- 
dodera rufipes Linn.), while other parts of the orchard were not at- 
tacked. Black-locust thickets are very common in the vicinity of the 
orchard, and an examination showed that large numbers of the 
beetles were present in them and were feeding on the young leaves. 
From the foreman of the farm it was learned that during March a 
fire ran through the locust thicket nearest the peach trees that were 
being attacked, and it was found that the leaves had not begun to 
reappear on the trees in the burned area. This evidently accounts 
for the injury—the beetles feeding on the peach, owing to the fact that 
there was no foilage on their natural food plant. Subsequent exam- 
inations made in widely separated localities in the State have shown 
that the beetles were present in greater or less numbers. They have 
been observed feeding on hazel, dogwood, and plum sprouts that were 
growing in locust thickets, but the latter foliage was most seriously 
injured. The larval and pupal stages are still unknown, but there 
seems to be no doubt that the insect hibernates at or beneath the sur- 
face of the ground, from which the beetles emerge early in the spring. 
The infested trees were sprayed with disparene late in April, but, as 
there was practically no foliage to hold the poison, very little good 
resulted. Later in the season the beetles disappeared and the trees 
were able to put out a crop of leaves. Outbreaks of this insect were 
reported in Virginia and Maryland several years ago, and were inves- 
tigated by Mr. E. A. Schwarz, assistant entomologist of the Bureau 
of Entomology. His report was published in Insect Life for the 
year 1893.4 
In June, 1904, a complaint was received from the Steubenville 
Traction and Light Company that some of their electric cars were 
being destroyed by insects. An investigation by Mr. Swezey showed 
that four cars which had been bought in 1902 had been somewhat
