XLYII. Leptuba Linn. 37.5S. (Or., "slender.") 



A genus of large size containing about 70 kno\\-n North Ameri- 

 can species. It is separated from Tiipocerus only by the absence 

 of poriferous impressed spaces on the antennae. Sixteen species 

 have been taken in the State, while six others perhaps occur. For 

 convenience, the species, whose range is such as to include Indiana, 

 are arranged in three groups. 



KEY TO GEOUPS OF INDIANA LEPTUBA. 



a. Thorax more or less triangular or bell-shaped, widest at base. 



6. Hind angles of thorax prolonged. Group A. 



66. Hind angles not prolonged. Group B. 



aa. Thorax nearly quadrate, more m- less rounded or sub-bell-shaped, usual- 

 ly constricted in front and behind, hind angles not prolonged. 



Group G.
