Central-American species of LHustylus (Biol. Cent.-Amer., 
Ins., Coleopt. iv. pt. 3, 1911, p. 290), and they are there- 
fore not included in the following synoptic table. The three — 
species described from Peru—viz., . humilis, Er., EZ. placi- 
dus, Kr. (Wiegm. Arch. 1847, p. 129), and E. funicularis, 
Kirsch (Berl. ent. Zeit. 1874, p. 890) —are also omitted, as 
they are unknown to me. Probably some of the species 
ascribed to the genus Compsus would be more suitably placed 
in Hustylus.
