IMPORTED INSECTS DISTRIBUTED IN 1893. 



Leaving Morgantown on the 20th of April, I proceeded to 

 the southern-most localities first, and commenced the distribu- 

 tion of the Clerids in the white pine forests of Raleigh county. 

 100 examples were placed here in two colonies of 50 each; one 

 on property owned by J. R. Beaty & Co., the other on proper- 

 ty owned by E. A. Monaghan. From Raleigh county I pro- 

 ceeded to Ronceverte, from which place I was taken in a buggy 

 by Col. Driscol, who represented the St. Lawrence Lumber Co., 

 and Mr. Dixon, who represented the Cumberland Lumber Co., 

 up the Greenbrier river, through the extensive white pine for- 

 ests owned by these two companies in Greenbrier and Poca- 

 hontas counties. Two colonies, one numbering 30 examples 

 and the other 70 were placed in the timber owned by the St. 

 Lawrence Co., and one colony numbering 100 specimens was 

 placed in timber owned by the Cumberland Co. 



From the white pine forests on the Greenbrier river, 1 pro- 

 ceeded into the spruce forests owned by the West Virginia & 

 Pittsburg R. R. Co., near the head of Williams river, in Poca- 

 hontas and Webster counties, where a colony of 100 examples 

 was placed. From this point, I returned on horse to Welch 

 Glade, in Webster County, and thence by rail to Morgautown, 

 where I arrived on May 12th, and on May 19th I went on to the 

 spruce forests in Randolph county, where I placed three colon- 

 ies in timber owned by the Condon-Lane, Boom & Lumber Co. 

 and returned to Morgantown on May 26th. 



METHODS OF LOCATING COLONIES OF IMPORTED INSECTS. 



In locating the colonies of Clerids, careful search was first 

 made for localities in which the conditions were most favorable 

 for the Clerids to obtain necessary food, and the adults to de- 

 posit their eggs without having to wander away from the colony. 

 The fact that all stages of the destructive pine bark beetle were 

 found to be dead in all of the dying trees examined, indicated 

 that the Clerid would have to depend upon other species of bark 

 beetles than the destructive species, upon which it was intended 

 to feed, the failure to find trees infested by living examples
