A FURTHER CONTRIBUTION TO THE HEMIPTER= 
OUS FAUNA OF OHIO.* 
Herbert Osborn. 
A preliminary list of the Hemiptera of Ohio was published in 
the proceedings of the Academy in 1900 (8th Annual Kept. ), 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 yet 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 ilie State fauna 111 this group. Several members 
of the Academy have kindly assisted in gathering material and I 
am especially indebted to Mr. Dury, Prof. MAtzstein, Mr. J. G. 
Sanders, Prof, Hine, Mr. O. H. Swezey and T. W. Ditto for such 
help. Mr. Swezey has secured a number of the Fulgoridae and 
Mr. Ditto most of the Aphididae included in this list. 
The Coccidae have been studied exhaustively by Mr. Sanders, 
and he has prepared an annotated descriptive list for the State' 
so I have not introduced detailed records here. Prof. P\ 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 IMr. Geo. B. King, Enf. 
Xctvs, XIV, page 204. 
Collections at Cincinnati, the south-east portion of the State 
and in Ashtabula County are especially desired.
