ENTOMOLOGICAL WORK IN OHIO. * 



Herbert Osborn. 



Probably the first careful work upon insects occurring within 

 the borders of Ohio should be attributed to Thomas Say, whose 

 extended residence in Indiana made possible a study of many 

 insects which were common to this region. While very few of 

 these described species, twenty-six so far noted, were from speci- 

 mens actually collected in Ohio, we may very fairly consider that 

 all of the species credited to Indiana might be considered as com- 

 mon within our area. Says' residence from 1825 till his death in 

 1834 on the Wabash River at New Harmony, Ind., covered prac- 

 tically the same faunal conditions as are to be found in this state. 

 Of the species described distinctly from Ohio the majority appear 

 to be aquatic forms and to have been collected quite largely along 

 the river; some of them, evidently, upon river boats which must 

 have been the means of transportation at the time. Very few 

 of the species recorded have economic importance. 



Between the time of Say and up to the beginning of Experi- 

 ment Station Work in the State there seems to have been a great 

 dearth of Entomological Workers and very few records for Ohio 

 insects appear in descriptive or faunistic papers. Among the per- 

 sons in the state who gave attention to Entomology during this 

 period we may note particularly Dr. Jared P. Kirtland who cov- 

 ered a wide range of Natural History subjects.
