Some two years ago Mr. E. V. Hines, of Winton, Queensland, sent me some fly-maggots which were attacking the sheep on his station. On breeding them out it was seen that they were referable to two different genera—Pycnosoma and Sarcophaga.

Specimens were later submitted to Mr. E. E. Austen, of the British Museum (Nat. Hist.), who informed me that they were Pycnosoma rufifacies (Macq.) and a Sarcophaga which was probably a new species.

I take this opportunity of extending my cordial thanks to Mr. Austen for his kindly assistance.
