the shoulders of the elytra, which, in that species, have a simple but very prominent 
tubercle without trace of carina.

To the locality given, add:—Mexico, Cordova (Sallé), Jalapa (Hoge); GUATEMALA, 
Cerro Zunil, San Juan in Vera Paz, Volcan de Atitlan (Champion); Panama, Volcan de 
Chiriqui, Bugaba (Champion). 
Closely allied to, if not the same species as, P. singularis (Thoms. Physis, ii. p. 61) 
from Cayenne. A specimen is labelled, evidently in error, Hypomia mewvicant, Thoms., 
in the Sallé collection. 
The genus Plerodia differs very slightly from Hypsioma, its chief differential 
characters being the very gradually thickened scape, carinated elytral shoulders, and 
more oblong form. 
GLYPTHAGA (to follow the genus Plerodia, p. 123). 
Glypthaga, Thomson, Physis, ii. p. 84; Lacordaire, Gen. Col. ix. p. 673. 
The only species of this genus that has been described is from South Brazil. The 
following small and obscure species agrees with it in generic characters, viz. the much 
shorter and less plane forehead, the head wide between the eyes, with the apex of the 
antenniferous tubercles prolonged into horn-like processes curving outwards. The 
general form is elongate oblong.
