ENTOMOLOGY. 



A DESCRIPTION OF SOME OF THE BEETLES (COLEOPTERA) WHICH 

 ARE MORE OR LESS INJURIOUS TO THE HORTICULTURIST. 



BY PROF. CYRUS THOMAS, STATE ENTOMOLOGIST. 



O. B. Galusha, Secretary of the State Horticultural Society. 



Dear Sir: According to promise, I hereby present you so much of 

 the Report on Entomology as I have been able to prepare in the very 

 limited time allowed me. As you will see, by examination, it consists 

 chiefly of descriptions of beetles injurious to trees and horticultural pro- 

 ducts, accompanied by short statements of such remedies as have been 

 proposed, or that I had to suggest. It is almost wholly extracted from 

 my forthcoming Report, and, as any one will see, it presents very little 

 relating to original research, but is simply a bringing together from vari- 

 ous sources what has been done in ofder to meet, in part, a want which is 

 now severely felt by horticulturists. I have freely drawn from the works 

 of others, and from my own previous papers, and wish here to acknowledge 

 my indebtedness to the works of Harris, Fitch, Packard, Walsh, Riley, and 

 Dr. LeBaron. This is, in fact, intended more as a supplement to Dr. Le- 

 Baron's Fourth Report than as a separate contribution. I have followed 

 his arrangement, and as that report is included in the published Transac- 

 tions of your Society of 1874, the reader is referred to it for the characters 

 of the families and genera, which will be necessary in determining species 

 not common. I may add that I have drawn freely from my paper pub- 

 lished in the fifth volume of the Transactions of the State Agricultural 

 Society. 



I am aware but little honor is to be acquired by bringing together 

 what has been done by others, but my desire is to aid our horticulturists, 

 as far as possible, to become acquainted with their insect foes, and in order 

 to do this a work of this kind is necessary, and was contemplated by the 

 lamented Walsh at the time of his death ; and so far as the Coleoptcra 

 are concerned. Dr. LeBaron has admirably prepared the way by his Fourth 

 Report, which has given a new impetus to the study of entomology in 

 Illinois. I regret I could not complete this order, but the time allowed 

 has been too short. Very respectfully, 



CYRUS THOMAS.
