NEW SPECIES or ALCIDION, A QENUS of LONGICORN COLEOPTERA. 

 BY H. W. BATES, P.L.S. 



Alcidion is a tropical American genus allied, to the European 

 Leiopus, but well-defined, by its unarmed thorax and sub-triangular 

 elytra, the disc of which bears on each side a longitudinal carina ending 

 in an apical spine. Many species exist undescribed in collections.
