Antcnnju 1^ lin. in length, rather stout, pitchy bhick, 

 ■with the basal joints rather paler; of joints 4 — 10 each is 

 a little longer than its predecessor. Head with two curved 

 lines on the front part, which meet so as to form an acute 

 angle on the middle of the head; antennal callosities stout, 

 but not greatly elevated ; the whole surface densely rugose, 

 quite opaque. Thorax strongly transverse; the sides 

 rounded and distinctly narrowed in front, behind the 

 middle with a short stout tooth, and behind this tooth cut 

 away, the hind angles l)cing distinctly marked and just 

 rectangular; the whole surface is densely and coarsely 

 rugose, quite dull ; there is no distinct impression along 

 the middle, and in front of the hind angles is a scarcely 

 definite longitudinal impression, reaching nearly to the 

 front margin. Elytra longer than the thorax, their 

 scidpture on each consisting of a sutural, and six other 

 fine, elevated, longitudinal lines ; the broad spaces between 

 these lines are peculiarly opaque, and are marked with 

 some indistinct transverse marks, w hich probably represent 

 obsolete coarse punctures. Hind body quite dull, densely 

 and rather finely punctured ; the apical segments and the 

 hind margin of the 6th segment reddish ; under surface 

 not so dull as the upper ; metasternum covered with 

 coarse punctures and with a fovea at the extremity in the 

 middle. Legs dull red.

 capite mutico, longitudinaliter striguloso ; prothorace 

 lateribus trisinuatis, dense fortiterque punctato ; elytris 

 lineis 6 elevatis; interstitiis transversim rugosis; abdomine 

 dense fortiterque punctato, apice dilutiore. Long. corp.

AntennfE 1^ lin. in length, stout, pitchy, the basal joints 

 obscure red; 3rd joint scarcely so long as 2nd, 4th a good 

 deal stouter than and qiiite as long as 3rd, 5 — 10 differing 

 little from one another in length, each slightly stouter 

 than its predecessor, 11th a little longer than but scarcely 

 so broad as 10th. Head Avithout impressions or lines, the 

 antennal callosities only being present ; the surface densely 

 covered with longitudinal ruga?. Thorax broader than 

 long, the front margin a little sinuate on each side the 

 middle, so that the front angles are somewhat prominent ; 

 the sides each with two notches, so that they exhibit three
