PACHYLIS. 
Pachylis, St.-Fargeau et Serville, Enc. Méth. x. p. 62 (1825) ; Stal, Ofv. Vet.-Ak. Férh. 1867, p. 538. 
The third joint of the antenne is widely dilated—a character which, taken with the 
non-dilatation of the outer side of the posterior tibie, is sufficient to differentiate. 
Pachylis from any allied genus here enumerated. This may be considered a truly 
Neotropical genus.
