and the right wings are female, and the left wings male and female. 3) A 

 gynandromorphous specimen of Papilio aegeus ornienus (Darnley Island; 

 June), in which the wings, both above and beneath, show irregular develop- 

 ment of the male and female pattern. 4) Eurycus eressida (Kuranda; June), 

 in which veins 5 and 7 of the left hindwing, instead of being 2^2 mm apart, 

 as in the right hindwing, approach one another and fuse for about 1 mm, and 

 then separate. 5) Two abnormal neurations in Belenois java teutonici,] amale 

 (Sydney; December), in which, on both forewings, veins 9 and 11 join one 

 another, and run together to the apex; and a female (Sydney; December), in 

 which vein 11 of the forewings fails to reach vein 2, as is usual. 6) Euploea 

 Sylvester, male (Cape York; April), veins 9 and 10 in the right forewing, 

 instead of being independent, are fused together for the greater part of their 

 length, and only separate just before reaching the costa: in the left forewing, 

 these same veins arise independently, but, at about half their length, fuse for 

 about 2 mm. 7) Junonia vellida (Lord Howe Island; February), in which, 

 though the right side is normal, the cell of the left forewing is closed by a 

 stout vein, and beyond this a second smaller closed cell has been formed. — 

 Mr. Froggatt exhibited a number of dipterous larvae taken from the wind- 

 pipes of kangaroos. Mr. Theo. R. Broughton, of Moramana, Walgett, 

 N.S.W. , who forwarded the specimens, reports that nearly every kangaroo 

 killed, and examined by him, in the Walgett district during the last two 

 months, was infested with the larvae. Though very different from the larvae 

 of the sheep nasal fly [Oestrus ovis), they evidently represent a species of the 

 same genus. Efforts are now being made to breed out and determine the fly. 

 — On some Australian Anisoptera [Ne ur opt era: Odonata], with Descript- 

 ions of new Species. By R. J. Tillyard, MA., F.E.S. — This paper brings 

 our knowledge of the group, in Australia, up to date. The new species de- 

 scribed are all interesting and distinct forms, including a new species of the 

 genus Synthemis from West Australia, a very peculiar Austrogomphtôs, and 

 a large and beautiful Petalura. A careful study is made of the closely allied 

 forms Austro aeschna parvistigma Selys and var. multipunctata Martin , the 

 conclusion being that these are really distinct species. Descriptions of the 

 hitherto missing sexes of several very rare species are also supplied. 



Abstract of Proceedings. October 30th, 1912. — Mr. Tillyard exhi- 

 bited the larval skin and freshly-emerged male imago of the very rare dra- 

 gonfly, Austroeordulia réfracta Tillyard, together with the type male and fe- 

 male for comparison. The latter were taken at Cooktown in January, 1907, 

 and only one other specimen is known. The larva was taken in February, 

 1911, at Heathcote, N.S.W., and has attained a considerable scientific inter- 

 est in already published papers as the "unknown larva X ; " which is the only 

 form yet discovered for the Group Idoeordulina (Subdivision of the Cor du - 

 liinae). One of the larvae was first found in 1907 at Heathcote, but died 

 in the act of emerging three years later ; so that it has taken five years to 

 discover to what species it really belonged. No imagines have ever been 

 seen or taken at Heathcote. Two other larvae are now practically full-fed 

 in Mr. Till yard's aquarium, and may be expected to emerge shortly. — 

 Dr. J. B. Cleland showed portion of a bull's hide, from the Hawkesbury 

 River, showing small, scattered nodules due to the distension of sebaceous 

 glands with numerous specimens of the acarid, Demodex follieulorum, var. 

 bovis. These massed acarids formed small yellowish caseous areas. Also
