ENTOMOLOGICAL WORK IN OHIO. * 
Herbert Osborx. 
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.
