TITE ANT-LIKE FLOWER BEETLES. 



Lawrence County; rare. June 5. The legs, in the single speci- 

 men at hand, are pale, whereas LeConte says thai they are piceous, 

 with the base of front thighs rufous. A member of the Austrori- 

 parian fauna. 



Tribe IV. ANTHICINI. 



To this tribe belong by far the greater number of species of the 

 family. They have the neck very small; mandibles emarginate at 

 tip ; middle coxa? nearly contiguous ; ventral segments five in both 

 sexes. Casey has divided the tribe into 16 genera, representatives 

 of ten of which have been taken in Indiana :
