XLVII. Leptura Linn. 1758. (Gr., "slender.") 



A genus of large size containing about 70 kno^vn North Ameri- 

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

 of poriferous impressed spaces on the antennte. Sixteen species 

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

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

 are arranged in three groups.
