A FURTHER CONTRIBUTION TO THE HEMIPTER= 

 OUS FAUNA OF 0HI05^ 



Herbert Osborn. 



A preliminary list of the Hemiptera of Ohio was published in 

 the proceedings of the Academy in 1900 (8th Annual Rept. ), and 

 a short supplementary list in the 9th Annual Report. 



Since these publications a number of new species have been 

 added and much additional data obtained concerning the distribu- 

 tion of some of the rarer forms hitherto noted. 



Some of these are of sufficient interest to merit a record at this 

 time, especially as a final report upon the group is 5-et impossible. 

 It is hoped that during the next two years sufficient collections 

 may be made in certain quarters of the State to render possible a 

 monograph of the State fauna in this group. Several members 

 of the Academy have kindly assisted in gathering material and I 

 am especially indebted to Mr. Dur)^, Prof. Wetzstein, Mr. J. G. 

 Sanders, Prof. Hine, Mr. O. H. Swezey and T. \V. Ditto for such 

 help. Mr. Swezej- has secured a number of the Fulgoridae and 

 Mr. Ditto most of the Aphididae included in this list. 



The Coccidae have been studied exhaustivelj^ b}^ Mr. Sanders, 

 and he has prepared an annotated descriptive list for the State, 

 so I have not introduced detailed records here. Prof. V. M. 

 Webster and Mr. A. F. Burgess published a list of this family 

 (Bull. U. S. Dept. Agriculture), and this list was republished 

 with certain revisions and additions by Mr. Geo. B. King, /f;//.

Collections at Cincinnati, the south-east portion of the State 

 and in Ashtabula County are especially desired.
