EXPERIMENT STATION BULLETINS. 245 



SOME INSECTS OF THE YEAR 1899. 



BY RUFUS H. PETriT. 



Bulletin 180. — Entomological Department. 



INTRODUCTORY. 



The aim of the present bulletin is to give short accounts of such insects as have 

 attracted special attention during the summer of 1899, together with advice as to 

 remedial treatment. Many other insects have been present and have done injury, but 

 guch only were selected as had not recently been noticed in the bulletins of this office. 



Correspondence relating to injurious insects is desired, and all aid and advice in our 

 power will be at all times freely and gladly given upon application. The best means 

 we have of finding out the needs of the farmer is through the letters sent us asking 

 lor advice in regard to specific insects. In writing for information, it is always best to 

 send one or more of the insects in question or some of their work. A piece of the 

 insect itself is usually more valuable than a lengthy description, and in sending speci- 

 mens, the best way is to enclose them in a tight tin box, with few if any air-holes 

 (insects require much less air than we do). Together with the insects themselves, it 

 is well to enclose some bits of the natural food for their use on the way. Always label 

 the package with the name of the sender to avoid confusion, as we often receive many 

 boxes at a time. 



Never dip specimens in ketosene or other insecticide before sending; in case of scales, 

 put them in a tight tin box. 



In sending insects or their work, always address to the Entomologist of the Experi- 

 ment Station, Agricultural College, Mich. 



The writer wishes to extend his thanks to Dr. L. O. Howard and Dr. C. L. Marlatt, 

 of the Department of Agriculture, Washington, D. C. ; to Miss Mary E. Murtfeldt of 

 Kirkwood, Mo., and to Prof. Herbert Osborn, of the Ohio State University, for deter- 

 minations of insects, reference to which is made in each case. He also wishes to 

 express his appreciation and thanks for the many kindnesses shown him by Prof. 

 W. B. Barrows, professor of zoology in the College.
