Under the Act a large area has been subjected to compulsory dipping 

 regulations from September 1918 till the end of January 1919, the 

 penalty for not complying with the gazetted notice being £10 to £50. 

 If, after that time, sheep are still infested, they must be reported by 

 the owner, the penalty for neglect to do so being £20 a day, under 

 the Stock Diseases Act of 1888. Under this Act, owners, managers 

 or agents (1) must report to the Chief Inspector of Stock or nearest 

 inspector of stock when sheep are infested with either lice or tick 

 [Melophagus ooinus] ; (2) must not move infested sheep away from 

 their usual pasture without permission of an inspector of stock ; 

 (3) must not move infested sheep along roads or reserves or allow con- 

 tact with other sheep; (4) must not expose infested sheep in any 

 saleyaid , whether public or private. 



The Acts and regulations which apply to the sheep louse also apply 

 to the sheep tick, Melophagus ovinus. 



Any inspector of stock may also place infested sheep in quarantine 

 until such time as he is satisfied that they have been dipped and 

 are clean. 



The paper concludes with a plan of a model dipping plant.

In a section dealing with Australian mosquitos as conveyors of 

 disease the species mentioned are : — Culexfatigans, which is not capable 

 of transmitting dengue fever, but which is the transmitting agent of 

 Filar ia bancrofti, and is apparently responsible for the distribution 

 of this disease in Queensland ; Stegomyia fasciafa, which is responsible, 

 and perhaps solely responsible, for the spread of dengue fever in 

 Australia, and is, at the same time, the transmitting agent of yellow 

 fever ; Ochlerotatus {Scutomyia) notoscriptus, Skuse, which is widely 

 distributed throughout Australia, but not known to convey any 

 disease to human beings ; Ochlerotatus (Culiceha) vigilax, Skuse, 

 the common bush mosquito, and Cidex sitiens, Wied, [Culicelsa 

 annulirostris, Skuse), a widely distributed species, which are not at 

 present considered responsible for the conveyance of any disease to 

 man, and Anopheles {Nyssorhynchus) annulipes, WLk., the chief 

 malaria transmitter in Australia and widely distributed throughout 

 the continent.

Stomoxys calcitrans is an exceedingly common biting fly, and is 

 probably met with throughout Australia. It mainly attacks horses
