_Caput breve, triangulare. Aures magnæ, anticè cutis plicâ, haud
dentatâ, partìm celatæ. Nares magnæ, rotundæ. Gulâ transversè
subplicata. Collum atque corpus haud cristata; hoc depressum, latum,
cute longitudinalitèr plicatâ. Cauda teres, basin versus
subdepressa, squamis fortibus spinosis verticillatis. Squamæ capitis
numerosæ, parvæ, rotundatæ, non imbricatæ—corporis minimæ, rotundæ,
subconvexæ, læves. Pori femorales et præ-anales nulli. Dentes
palatini._
The propinquity of this genus both to _Oplura_ and to _Doryphorus_ is
very obvious. It differs, however, from both in several structural
characters. From the former in the absence of denticulations on the
anterior margin of the ear, and of a nuchal crest; from the latter in
the presence of palatine teeth. Its place is probably between these two
genera.
