Subgenus Chlorion Latreille 
The two species of this subgenus that have been recorded from 
the Islands are not represented in the Philippine collections at 
my disposal. The record of Chlorion splendidum is open to 
question, and it may be well to eliminate this name from the 
list until specimens have been collected. 
Chlorion (Chlorion) lobatum (Fabricius). 
This beautiful species can be easily recognized by its metallic 
body. 
Chlorion (Chlorion) splendidum (Fabricius). 
This species has been recorded only in the Brown catalogue, 
and its occurrence in the Islands needs verification.
