Has the appearance of Leptura, but differs in the form of the head and eyes, as 

 well as in the situation of the antennae. The ligula instead of being divided into 

 long diverging lobes, is formed as in Toxotus. This genus contains a large portion 

 of the old genus Pachyta, with some of Mulsant's Anoplodon.
