Short, rathiT stdut. subdepressed. Dull black, 

 clothed with rather long yellowish pubescence, 

 which is irregularly disposed so as to leave 

 abraded smooth spots. Thorax quadrate, broader 

 than long, sides feebly rounded, surface coarsely 

 and rather sparsely punctured. Elytra broader

 sparse, fine punctures intermingled with lai-ger

Division IV. LEPTUROIDES. 



This division comprises those meiiil)ers of the snl)family Cerma- 

 byeina% in wliieh the base of antennji^ are not enveloped by the eyes, 

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

 a small notch or emarg-ination, and almost always finely granu- 

 lated; front coxiB 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 '\slcnder or attenuated," in allusion to the 

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

 base uiore or less elevated al)ove 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 u])on the ti'unks and about the roots of trees, where the mem- 

 liers of the preceding genera are usually found. 



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

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

 and species.
