SYNOPTIC TABLE OF THE SPECIES OF AULICUS (COL.). 



BY A. B. WOLCOTT, CHICAGO; ILL. 



The genus Atdicus, as now restricted, is confined to North, Central 

 and South America, the various species giving the genus a geographical 

 range which extends from Texas to Colombia. The Australian species 

 formerly placed in Aulicus, but which are not congeneric with our species, 

 have been referred to the genus Phlogistus Gorham. 



During the progress of some studies of American Cleridae, the writer 

 found it expedient to construct a table of the known species, which is here 

 presented, with the hope that it may be of service to others.

in front (Aulicus, sens. str.).
