REPORT OF THE ENTOMOLOGIST. 67 
Chrysobothris calcarata, (Mels.,) (femorata, Lap.,) (Agricultural Report, 
1868, p. 92, fig. 97,) the flat-headed apple-borer, or thick-legged Buprestis, 
which is said to injure apple, peach, and oak, deposits its eggs on the 
bark, and the larva is generally found on the south or southwest side of 
the tree, preferring trees that have been “sun-scalded.” It bores into 
the solid wood under the bark, and is stated by Mr. Packard to remain 
as larva one year. Dr. Fitch, in his fifth report, 1858, states that 
before apple trees were introduced the larva probably fed on oak. The 
perfect insect appears from May to July, and may generally be found 
sunning itself on the trunks of the trees. To protect maple and other 
trees from the attacks of the Chrysobothris, applications of soap on the 
trunk and larger branches in May and during the summer are said to be 
an effectual remedy. 4 
The larva of another very similar insect belonging to the same family, 
Deerea, divaricata, (Lec.,) mines in the sap-wood and under Fig. 6. 
the bark of apple, beech, cherry, peach, and plum trees. The 
insect itself can be found from June to August on the trunks 
of these trees. In order to preserve the trees from these 
insects, it has been recommended to wash the trunks with 
some alkaline solution —hard or soft soap, thinned to a proper 
consistence with, salt brine, to which tobacco stems are 
addei—from June to August, repeating the wash after 
heavy rains or dews. 
Some raspberry canes, sent by Mr. Charles Catpenter, of Kelley’s 
Island, Obio, which had been injured by some unknown Fig. 7. 
insect, were received in January. At first it was sur- U4 
mised to be the work of Oberea tripunctata, or raspberry- 
borer, an insect which is known to injure raspberry- 
plants by burrowing in the pith, but after the larva had 
changed to the perfect insect, it was found to be Agrilus 
ruficollis, (Say,) a small wedge-shaped beetle, with a ruby- 
red thorax and blackish wing-covers. The injured canes 
presented the appearance of a swelling in the stem, form- 
ing several ridges. Mr. Saunders, in describing an in- 47 
jury done to raspberry canes in Canada, and ascribing it fi} 
to Oberea tripunctata, states that “the new cane is first 
girdled near the tip in two places, one ring very nearly 
av inch below the other.” All the specimens sent by 
Mr. Carpenter certainly presented that appearance of 
girdling when the outer bark was scraped off with a knife. The perfect 
insects caine out very early in the spring, owing to their having been 
kept in a very warm room. Raspberry or blackberry canes presenting 
swollen stems and a diseased appearance should be cut off in winter and 
immediately burned. 
-An insect of the same family, Agrilus egenus, (Poey,) (Agricultural 
Report, 18638, p. 92, Fig. 103,) of a greenish, metallic color, and wanting 
the ruby-red thorax, was found in Virginia a few years ago in great 
numbers, feeding on the leaves of the locust tree, Robinia pseudacacia, 
the foliage of which was completely riddled with small holes, which had 
been eaten by this insect. 
The so-called wire-worms are the larve of different species of chick- 
beetles, or snapping-bugs, as they are vulgarly called. In the Fig. 8 
larval state they feed upon roots of grass, maize, potatoes, &e., iia 
and are especially troublesome in land that bas been recently 4°¥ 
plowed up from the sod. Agriotes manchus (Lec.) is a very common t 
species, and is said by Harris to resemble the wire-worm of Europe.
