PRELIMINARY REPORT ON THE INSECT ENEMIES OF 

 FORESTS IN THE NORTHWEST. 



OUTLINE OF TRIP. AND LOCALITIES VISITED. 



I left Morgantown, W. Va.. April 9, and Washington, D. C, April 

 12, and, going by the southern route through Texas, New Mexico, 

 Arizona, and California, arrived in San Francisco on the evening of 

 April 17. The following day (April 18) was spent in visiting the 

 University of California, at Berkeley, where I called on Professor 

 Woodworth, entomologist, and Prof. J. B. Davy, botanist, of the 

 Agricultural Experiment Station, who offered every facility and gave 

 valuable assistance in nry study of the native forest trees represented 

 in the university arboretum. Here I collected numerous species of 

 Scolytids from the pines and other conifers. 



On April 19 I proceeded to Guerneville, Cal. , some 70 miles north 

 of San Francisco, to investigate the insect enemies of the California 

 redwood {Sequoia sempervirens), and, in addition to several other spe- 

 cies of insects collected from the bark and wood of this tree, I found 

 that PhloeosiniijS cristatiis was a very common enemy. 



On April 20 considerable time was spent in Golden Gate Park, San 

 Francisco, studying the indigenous trees of the Pacific coast repre- 

 sented there, and in collecting specimens of insect enemies of the park 

 trees. I also called on Mr. N. Hoffman, who is a dealer in imported 

 and native woods, and is well informed on the timber interests of the 

 Pacific coast, and obtained from him some valuable information. 



I left San Francisco to pursue my investigations in the vicinity of 

 McCloud and Sisson, Cal. , where I had been informed some timber 

 was dying, and arrived at the former place, a small village in the 

 heart of the yellow and sugar pine forests, on the southern slopes of 

 Mount Shasta, April 21. Among the more important observations 

 made here was the discovery of a bark-beetle of the genus Den- 

 droctonus killing the yellow pine, and another of the genus Scolytus 

 doing great damage to living fir trees. In addition to this a large 

 number of heretofore unrecorded facts were noted regarding the insect 

 enemies of the spruce, fir, cedar, pines, etc. The owners of the timber 

 in this locality expressed themseh^es as much interested and pleased 

 that these subjects were being investigated, and they kindly offered
