Studies in the Tenebrionid Tribe Eleodiini Order 



Coleoptera. 



BY F. E. BLAISDELL, SR. 



It was originally intended to include in the writer's recent 

 monograph of the Eleodiini a list of the genera, subgenera, 

 species, varieties and forms in the order that they should be 

 placed in a cabinet arrangement; also, a philosophical discus- 

 sion of the taxonomic grades and autogenesis, but it was found 

 advisable to reduce the size of the manuscript as it exceeded 

 a desirable magnitude. 



The cabinet arrangement is now presented to aid Coleop- 

 terists when going over their material. The formae are not 

 to be given in a check list arrangement. 



More recent studies by the author in the East and at home 

 have determined several changes in certain of the grades, in 

 order to present a more satisfactory status of relationships. 



Through the courtesy of Col. Thos. L. Casey the writer had 

 an opportunity to examine his types, such as were not at hand 

 while the monograph was in preparation. 



The following is the list with such changes as are deemed 

 absolutely necessary for a presentation of more recent no- 

 tions regarding relationships. Formae or incipient races are 

 given in italics; true synonyms are in italics and parentheses.
