Willis Blatchley was an entomologist
and geologist. He was the Head of the Science Department at
Terre Haute High School in Indiana from 1887-1893 and the State
Geologist for Indiana from 1894-1910. His research interests
were Coleoptera, Orthoptera, Hemiptera, and the freshwater molluscs
of Indiana. Blatchley is probably best known by entomologists
for his giant tome on the Coleoptera of Indiana, published in
1910, as well as his 11 papers (1927-1930, Florida Entomologist)
on the Scarabaeidae of Florida. Blatchley described several
species of Aphodius, Ataenius, Onthophagus,
Hoplia, and Tomarus, among others.
