Kncx and Posey counties; frequent. July 

 24-August 2. Probably occurs over the area covered by the Aus- 

 trorii)arian fauna, of which it is n striking member. It is com- 

 monly known as the "fifA'-eater," and in the South often flies in 

 great nuiiil)er.s liy night, especially in sandy districts, making a 

 loud buzzing noise similai' to that made l>y the May-beetles {Larh- 

 nostcrna). The larva? feed upon the roots of grass and sometimes 

 are harmful to strawb(-rry and other plants. When they move they 

 crawl upon their liacks, making no use of their short legs. AUor- 

 hina Burm., to which the species is usually ascril)ed, is a South 

 American genus.
