Division IV. LEPTVROIDi:>t. 



This division comprises those members of the subfamily Cerma- 

 byeinae, in which the base of antenna; are not enveloped by the eyes, 

 which are usually rounded, sometimes entire, but more often with 

 a small notch or emargination, and almost always finely granu- 

 lated; front coxa3 conical, except in the first tribe; head narrowed 

 behind the eyes and the thorax narrowed in front, the union of 

 these two parts giving the appearance of a neck of greater or less 

 length. The name of the typical genus, Leptura, is derived from a 

 Greek word meaning "slender or attenuated," in allusion to .the 

 usually tapering form of the elytra, which also often have their 

 base more or less elevated above the level of the thorax. As a gen- 

 eral rule the species are more active than those of the preceding 

 groups and many of them fly by day and occur upon flowers rather 

 than upon the trunks and about the roots of trees, where the mem- 

 bers of the preceding genera are usually found. 



The division is separated into five trilies, all probably repre- 

 sented in Indiana, tlioudi four of them each only by a single genus 

 and species,
