NOTES ON THE BUTTERFLY, CATOPSILIA SCYLLA 
GORGOPHONE, F. HIND A BUTLER 
(Lepidoptera, Pieridae) 
By A. N. Burns, B.Sc., F.R.E.S., F.R.H.S., Entomologist, 
National Museum of Victoria. 
This butterfly was originally described by Butler (1) in 1870 
as a form of Catopsilia pomona pomona Fabr., and was catalogued 
as such by Waterhouse and Lyell (2) in 1914; but in 1932, Water- 
house (3) includes this form under C. scylla gorgophone Boisd. 
The following notes made from actual field observations and 
breeding experiments by the writer at Westwood, 30 miles west 
of Rockhampton, on the central Queensland railway, will clearly 
show that f. hinda Butler is really a form of C. scylla gorgophone. 
Both C. pomona and G. scylla gorgophone occur abundantly in 
this locality, the former .species at times in great flights the general 
direction of which is from north to south. C. scylla gorgophone 
occurs freely during the months of October, J anuary and March, 
though specimens are to be collected from September until May. 
The larvae of each species feed on different species of Cassia ; 
those of C. pomona on Cassia fistula (introduced) and on a native 
species, and G. scylla gorgophone on Cassia glauca. Many hundred 
C . pomona were bred from larvae and pupae taken from the food 
plants, and from these were obtained many interesting varieties, 
including the female form catilla and intergrades between this 
fonn and the normal female, but no hinda. 
A number of different batches of larvae of G. scylla gorgophone 
was also bred through, and four hinda in all were obtained. During 
the same season, another hinda was captured flying with gorgo- 
phone. The writer has observed occasional specimens of gorgo- 
phone flying with C. pomona during a “flight.” buch flights 
consist of all possible forms of pomona, and twice only has C. 
gorgophone hinda been identified in one of these flights. Theii 
occurrence together cannot therefore be taken as supposing hinda 
to be a form of G. pomona.
