examples of Cerco'pithecus schmidti, from the Upper Congo region, 

 and Otospermophiliis heecheyi (Californian ground squirrel). The 

 degree of pathogenicity of the parasite is problematical. It is probably 

 not sufficient to cause death. The mode of entry is not knowU; but 

 it is presumed that ova or larvae are inhaled, develop in a bronchus, 

 and thence penetrate into the lung parenchyma. It is possible that 

 the natural habitat is upon straw used for bedding, or upon fruit. 

 According to Landois and Hoepke, the ova are swallowed with food ; 

 the larvae develop in the intestine, then penetrate the intestinal walls 

 into lymphatic spaces, eventually reaching the lungs through the 

 thoracic duct and blood stream. This route seems unlikely. 



Among birds, the best known Arachnoid infestation is that of hens 

 by Cytodites midus. The parasite occupies the air spaces and bronchi, 

 causing a fatal disease. A few cases have been recorded among human 

 beings, though the parasites have not been found in the lungs. The 

 source of infestation in man is unknown.

Stegmnyia fasciuta, the chief carrier of yellow fever, is abundant in 

 Fiji, and in view of the opening of the Panama Canal is of primary 

 importance. The question of the formation of a mosquito bureau at 

 Suva is under consideration. The following are the species of mosquitos 

 recorded in Fiji :~Cidex fat igam, C. nocturnus, C. jepsoni, Stegamyiu 

 fasciata, S. jjseudoscutelhris, Finlaya j>oicilia, Phoniomyia sp., and 

 Taeniorhynchus brevicelhdus. 



A notable diminution in the numbers of Musca domestica (house-fly) 

 occurred in the province of Bua. The decrease was attributed by 

 some to improved sanitation, by others to the work of the wasp, 

 PoJistes hehraeus, which is predaceous on the adults and larvae. 

 The latter theory is the more probable, as certain social wasps are 

 known to feed their larvae on flies. According to Illingworth, house- 

 flies in Fiji are controlled by a small brown ant. Large numbers of 

 Stomoxys sp. were found in one paddock, breeding in horse manure. 

 These could be checked bv dressingrs of lime.

The species described in this paper were taken between March and 

 June in various localities in New South Wales. With the exception 

 of Spaniopsis clelandi, which occurs on the mountains in sunmier, all 

 the others are autumn or winter forms. They are all found on the 

 sandstone ridges, and not in the gullies, and probably have a wide 

 distribution along the coastal districts of eastern Australia, but so far 

 have not been found west of the mountains. It has been suggested 

 that the flies may have a causal connection with '* bung eye," but in the 

 opinion of the author this is unlikely, since this disease is more prevalent
