Group ONCIDERINI, 
A characteristic American group, very numerous in species and genera within the 
tropics, and sparsely represented in the temperate zones. In a natural arrangement 
it would be brought into contiguity with the Apomecynini and Niphonini, from which 
Lacordaire widely separates it. His “ groupe’’ Onocéphalides may, with advantage, be 
combined with the Onciderini.

TYBALMIA. 
Tybalmia, Thomson, Physis, ti. p. 44. 
Five species have been described of this genus, which has a similar range to the 
preceding. All those species of Jschiocentra which have porrected frontal horns in the 
male, however, must be added, for the reasons given below in the remarks on 7. turbida: 
these include J. jaspidea, niphonoides, maculosa, heraldica, and others.
