from Woodah Island, in Blue Mud Bay, have the subapical patch beneath very 

 faintly visible, but are larger than any specimens of E. p. ivalkeri in our col- 

 lection. Mainland specimens from Roper River are very typical E. p. zvalkeri. 

 It is also distinct from E. perdita perdita. Tongura is a Groote Eylandt native 

 (Ingura) word meaning "pipeclay" or "chalk." 



Elodina padusa, Hewitson. 



A perfect specimen of this species was taken at Mount Painter, in the 

 Flinders Range, by the late H. G. Stokes. This is a new record for South 

 Australia. Mr. R. Illidge has also taken it at Brisbane, though not abundantly. 

 It is the rarest of the genus and has only been recorded so far from single 

 specimens taken in New South Wales, Victoria, and North-western Australia. 



Family PAPILIONIDAE. 



Papilio amyntor amphiaraus, Felder. 



This interesting species, the only butterfly peculiar to Norfolk Island, has 

 not previously been figured. The specimen, a female, was taken by Mr. A. 

 M. Lea. 



EuRYCus CRESSiDA CASSANDRA, Waterhousc and Lyell. 



Groote Eylandt specimens are larger than E. c. cassandra; in the male they 

 approach typical E. c. cressida, but the wings of the females are completely scaled 

 * beneath and are distinct from the latter. The butterfly was the most common 

 and conspicuous one seen on the island. 



The female was discovered laying eggs on one of the Aristolochia vines. 

 The eggs are globular, yellow, with sixteen rows of raised, orange-coloured 

 tubercles, arranged symmetrically ; apex with an orange tubercle, the base orange. 

 Diameter, 1 mm. The larvae hatched in ten days. Adult larvae were also 

 obtained, but are not now in condition to be described.

Parnara mathias. Fab. 



A pupa was found among grass stems on Groote Eylandt during March, 

 and the butterfly, a female, emerged on May 12. The period of pupation seems 

 long. The pupa was green, smooth and cylindrical, tapering gradually to the 

 anal extremity. Head prolonged in a smooth-pointed horn. Apex of abdomen
