Donovan expressly states that his specimen of this insect corresponded with that 
in the Linnaean cabinet. It also agrees with the description of a Javanese butterfly 
described in the Encyclopedic Methodique as the true Thrax. This circumstance ren- 
ders doubtful the references to F abricius, Clerk, and Cramer, who has figured three 
species, regarded as varieties of Thrax, under the names of Papilio Salus, Sebaldus, 
and Ramasis.
