OSAGE ORANGE INJURED BY WOOD BORERS. 



By Philip Laurent. 



In the suburban parts of Philadelphia the Osange Orage is ex- 

 tensively used in forming hedges around fields and gardens, and 

 for this purpose it excels all other plants, as aside from its fine 

 appearance it forms an almost impregnable barrier against tres- 

 passers. 



It was on July 4, 1895, that I first had my attention called to 

 the number of Dorcaschema wildii and alternatum that were in- 

 festing a certain hedge near my home at Mt. Airy. In the course 

 of an hour's time, with the aid of my friend, Mr. Horace Rodd, 

 I secured seventy-five wildii and about twice that number of 

 alternatum. During the following Winter I secured from this 

 hedge — which was about one hundred yards in length — two sec- 

 tions from the limb of a tree, each section being about four feet 

 in length and from three to five inches in diameter (see Plate II). 

 On arriving home I cut the sections into smaller ones and placed 

 them in the breeding cage. The first beetles made their appear- 

 ance on June 18, and from that time until the middle of July 

 they continued to emerge. Nearly all the specimens proved to 

 be alternatum, only one or two wildii making their appearance. 

 Two specimens of Neoclytus erythrocephalus also emerged. la 

 all thirty-eight specimens emerged.
