ORTHOCERUS, Latreille (Sarrotrium, 111.). 



This genus contains three European species, and one from Central 

 Asia ; the single species found in Britain extends over northern Europe 

 and Siberia ; they may be known by the peculiar development of their 

 antennae. 



O. muticus, L. (clavicornis, L. ; hirticornis, De G-.). Greyish-black, 

 clothed with very fine whitish pubescence ; head large, uneven, sub- 

 quadrate, with small, prominent eyes ; antennae fusiform, very stout 

 and broad, broadest in middle, joints 4-9 plainly broader than the 

 remainder, pilose and set with long setae ; thorax a little narrower in 

 front than behind, with the posterior angles very blunt, and the anterior 

 angles projecting, with a deep broad longitudinal furrow bounded on 

 each side by an indistinct raised line ; elytra with rows of deep, crenu- 

 late, punctures, second, fourth, and sixth interstices strongly raised; le^s 

 rather short, tarsi setose beneath. L. 4 mm.

This genus contains a few species, three of which are found in Europe, 

 and one has lately been described from Japan by Dr. Sharp ; as regards 

 this genus, and in fact all the genera of the Colydiidee, it must be 

 remembered that owing to their retiring habits the species are perpetually 

 passed over, and that consequently many of those genera that are now 

 restricted to some two or three species, may ultimately be found to bo 

 very numerous ; the genus may be recognized by its broad form, much 

 raised and scabrous surface, and the serrated sides of thorax and elytra.
