EPISTEME. 65 



arisen respecting the true Papilio hyalc of Linnceus. While 

 my son, Dr. W. Egmont Kirby, was comparing some of the 

 figures in Jardine's " Naturalist's Library " with the British 

 ^[useum collection, he noticed that the original figure of E. 

 viaadatrix had nothing to do with the species bearing that 

 name in the collection, but agreed with a specimen labelled 

 E. ireneu (Boisduval). On investigating the matter, it was 

 discovered that after figuring and describing E. viaculatrix 

 in 1 84 1, Westwood himself figured and described a totally 

 different species in 1848, which has gone by the same name 

 ever since ; the true E. maailatrix having again been mistaken 

 for E. ircfiea (Boisduval), which I have noticed above, and 

 which proved, on comparison with Boisduval's description, to 

 be the same as E. communis^ Butler, the description of which 

 was [)ublished about the same time as Boisduval's description 

 of E. iroiea. 



The true E. viaculatrix appears to be a rare species, of which 

 the British Museum possesses only one specimen. Westwood's 

 second E, maculatrix is herewith named
