a knowledge of the Rhopalocera of Australia. 9 
mere waste of time to repeat them here: as Professor 
Westwood, in first characterizing the group Xenica as a 
subgenus, did not mention which of the species included 
therein was his type, I had an admitted right, when I 
split it up into three genera, to select any one ; of the spe- 
cies as type, and I was per feetly Justified in retaining that 
type in its original position (making it a subgenus of 
Epinephele, as it had formerly been of Lasiommata). 
Kirby in this, as in several other instances, went out of 
his way to sink properly constituted genera: he would 
have done much better had he restored Thecla betule to 
its genus and turned out all the pretty invaders which are 
often now referred to the Fabrician genus, to the exclusion 
of the type; this must be done eventually,—indeed most 
Entomologists are doing it already. 
Mr. Masters has wrongly referred the species of Hypo- 
cysta to Cenonympha (not to Mycalesis); but I believe 
that Cenonympha does not occur in Australia. 
Mr. Masters also asserts that 7. Hecabe is = T. Sari 
of Horsfield (of which we possess the type); I can assure 
him, however, that the two insects are as distinct as 
almost any two in the genus: J. Sari is confined to Java, 
Borneo and perhaps Malacca. 
Pieris aruna of Masters (nec Boisduval)'is Delias in- 
ferna of Butler: D. ceneus does not occur in Australia, 
nor does a single typical Pieris ; the species in the Cata- 
logue by Mr. Masters are referable to the three genera 
Delias, Appias and Belenois: Eronia does not occur in 
Australia, but Nepheronia may. Callidryas is now re- 
stricted to the C. eubule group, the Old World species 
being all referable to Catopsilia. 
C. evangelina does not occur in Australia, nor does 
C. pyranthe. In the Papilionine, I would correct the 
following errors— Ornithoptera euphorion and O. poseidon 
are sexes; Papilio erithonius is not = P. sthenelus, and 
does not range into Australia; P. sarpedon is quite dis- 
tinct from P. choredon, and P. ulysses from P. joesa ; 
P. sarpedon ranges from N. India to Borneo, but I think 
no farther; P. ulysses is confined to the Moluccas, and is 
as distinct from P. joesa as it is from P. philippus, 
P. pericles or P. telegonus. P. lycaon, Westw., has 
nothing whatever to do with P. eurypylus, L. 
In the Hesperide, 1 would suggest that the generic 
designation Protedes he abandoned, P. vulpecula of 
Pritiwitz not being a Protcides, but = Netrocoryne
