Jan., 1906.] 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 thev 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 hst 

 represents the record of the material in the collection of the 

 Entomological Department of the Ohio State University, which 

 has been 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 :
