Here lie lias substituted the term Mtlieocerus for 

 Heterotoma, repeating, without the least misgiving, his 

 curious error about the antennas; he abandons the 

 term Isotoma, replacing it by the old generic name 

 Podiira; and he proposes a new generic term, AcU- 

 cranus, which, however, is synonymous with Burmeis- 

 ter's Lipura. 



The SinyntJmridce he divides into two genera, charac- 

 terised as follows : 



Smyntliunis. — Antennae four-jointed ; no dorsal tu- 

 bercles. 



Dicyrtoma. — Antennge eight-jointed; two dorsal tu- 

 bercles. 



Of the former, he describes six species, four being- 

 new ; of the latter, two species, both new. I have 

 sometimes been disposed to regard Dicyrtoma as sy- 

 nonymous with my genus Faplrkis. In this case, 

 however, M. Bourlet is mistaken in regarding the 

 antennae as eight-jointed.
