Report on the Mosquitoes of Ohio. 
439 
Several states have undertaken special investigations of the 
mosquito problem, and as a result Dr. Felt reports fifty species 
as occurring in New York and the adjoining states. Dr. J. B. 
Smith has found forty-two species in New Jersey, and Dr. 
Dupree has collected thirty-seven species in Louisiana. 
Doubtless some of the species found in these states do not 
occur in Ohio, as they are either inhabitants of a warmer climate, 
or breed in salt or brackish water found along or near the sea 
coast. 
It is the object of this paper to list the species that have been 
collected in this state, giving the localities where they were taken 
and the dates the captures were made, and it is hoped that 
sufficient interest may be aroused in the subject so that further 
investigations may be made of this important family. 
Some collecting was undertaken by the writer at spare 
moments during the past summer, but this resulted in the 
collection of only a few species. The accompanying list 
represents the record of the material in the collection of the 
Entomological Department of the Ohio State University, which 
has l)een placed at my disposal through the courtesy of Profs. 
Osborn and Hine ; and the assistance received from the latter 
has made it possible to prepare this report. Records of speci- 
mens are also included, which were collected by Mr. W. E. 
Evans, a student in Entomology at the Ohio State University, 
and credit is given in each case. I am also indebted to Dr. L. 6. 
Howard, Entomologist to the United States Department of 
Agriculture, for having placed at my disposal the notes in his 
office on species received from Ohio, and to Mr. D. W. Coquillett 
for determining many of the species in the following list ;
