This genus, named long ago, as above, by Mr. MacLoay, con-' 

 nccts Cerambyx witli Molorchus, Necydalis, and R/iagiian. With 

 the latter indeed it has little other connexion than from the simi- 

 lar shape of its elytra,^ which grow gradually narrower towards 

 the apex ; from Cerambyx it is distinguished by its antenniie ; and 

 from Molorchus and Necydalis by its elytra, scarcely at all shorter 

 than the wings, and by its disticho-raraosc antennae.
