1109 



Southern half of State ; rather scarce. April 3-May 26. Four 

 of the varieties have been taken, viz., air a in Jennings and Putnam 

 counties; hepatica in Hancock, Jackson, Crawford and Posey coun- 

 ties ; vittata in Jackson and Posey and trivittata in Posey.

The members of this genus are smaller, being proportionally 

 shorter and more robust, than those of Orsodacna. . The punctua- 

 tion is very coarse and the thorax has a large blunt tubercle on 

 sides. Three species have been taken in the State and another prob- 

 ably occurs.
