KEY TO INDIANA SPECIES OF GROUP I.

<iti. Form more slender and depressed; head equal in width to thorax: ely- 

 tra pale, distinctly longer and wider than thorax. 



r. I\ves of normal size and prominence, situated at distinctly less than 

 twice their own length from base of head; elytra pale reddish-yel- 

 low, with a piceous cloud near scutellum. RUBIDA. 

 re. Eyes notably smaller, situated at twice their own length from base; 

 elytra pale dull yellow. 821. AMBIGUUM. 



L. rtnffdli Lee., 4 mm. in length, was described from Pennsyl- 

 vania, Florida and Kansas, and therefore probably occurs in* In- 

 diana.
