A communication from a lady of Boise, Idaho (April 20,1893), givesthe following particulars of some • fungus gnats, believed by her tohave been injurious in her greenhouse: The fly, or flies more properly, for there are thousands of them inmy greenhouse, congregate wherever there is the least leaf mold ormanure (cow), no matter how old or well-rotted it may be.
